14 3. SOFTWARE CONFIGURATION 3.1 Configuration tools of the PROFINET IO controller VPGate PROFINET SERIAL can be configured via the PROFINET network configuration software and is sent by the PROFINET IO controller when the network is initialised. The following detailed configuration was carried out using the "HW Config" configuration software of SIEMENS. Nevertheless, the procedure is the same for all configuration software. 3.2 Integrating VPGate into a project Before proceeding further, a project must be created in the engineering tool with a hardware configuration that contains at least one PROFINET network and one IO controller Importing a GSDML file into the engineering tool The GSD file allows using VPGate as a PROFINET IO device. It is called GSDML-V2-3-VPGate xml and can be found in the VPGate CD provided with the device. The GSD file can also be accessed via the web server of VPGate (refer to paragraph 10). This GSD must be imported via the PROFINET network configurator for VPGate to appear in the catalogue of devices that can be inserted in the network. Figure 7: Importing the GSD into the device catalogue Integrating VPGate The steps are as follows: Integrate VPGate into the network from the PROFINET device catalogue. The head module to be integrated depends on the desired operating mode: MODBUS MASTER mode MODBUS SLAVE mode TRANSPARENT mode VPGate PROFINET to serial user manual June 2017 PROCENTEC 14/104

15 Figure 8: Integrating VPGate into the network Configure the desired PROFINET name (this value is configured via the DCP in VPGate). This name allows the IO controller to identify the device when the network is switched on Figure 9: List of devices that can be accessed via DCP Figure 10: Naming a device via DCP In the device properties in the network configuration tool, define the same PROFINET name that was previously configured in VPGate: 4 VPGate PROFINET to serial user manual June 2017 PROCENTEC 15/104

16 1 2 Figure 11: Configuring the device name in the configuration tool The cycle time for each device in the PROFINET network is determined at the level of the IO controller. The possible cycle times are 2, 4, 8, 16, 32, 64, 128, 256 and 512 ms. 3.3 General configuration of VPGate 3 head modules are available, each corresponding to a communication mode on the serial link: Gateway configuration in the TRANSPARENT mode Gateway configuration in the MODBUS Master mode Gateway configuration in the MODBUS Slave mode General parameters The parameters described below are common for all 3 head modules. Once VPGate is inserted in the PROFINET network, the serial link must be configured using the following parameters: Figure 12: Common parameters of the serial link VPGate PROFINET to serial user manual June 2017 PROCENTEC 16/104

17 Name Description Possible values Baud rate Communication speed of the serial link (in bits/s) None Parity Presence or absence of a parity bit Even Odd Stop bits Number of stop bits 1 2 Data bits (*) Number of data bits 7 8 Timeout Time delay before signalling the absence of data received on the serial link default: 1000 ms ms Interchars timeout Maximum time between 2 characters of a frame. 1.5 characters + 0 to ms Interframe silence Time delay to be complied with after receiving a frame, before it can be re-issued. 3.5 characters + 20 to ms (*) MODBUS RTU has 8-bit data. MODBUS ASCII has 7-bit data. VPGate PROFINET to serial user manual June 2017 PROCENTEC 17/104

18 Defining the diagnostic management: Figure 23: MODBUS MASTER mode diagnostic Name Description Possible values Diagnostic alarms Enable or disable alarms sent by VPGate on PROFINET to the IO controller. Yes No Disabled (1) Digital output mode Defines the behaviour of the Digital output if the Digital Output module is not plugged into an VPGate slot. On PROFINET SF (2) On serial link SF (2) On PROFINET and serial link SF (2) (1): In the Disabled mode, the Digital output may be controlled by the Digital Output module if it is plugged in. (2): In these modes, the relay will be closed if there is a fault in the selected network: On PROFINET SF when communication with the PROFINET controller is lost. On serial Link when there is a communication error on the serial link. On PROFINET and serial link SF in case of both. 3.4 Configuration in TRANSPARENT mode In this mode, data exchange is full duplex, without the master/slave concept. It is required to define the size of frame received/sent by using the modules provided with the transparent mode. The frames detected on the serial link are immediately copied in the inputs bytes modules plugged in VPGate. Similarly, if the format of a serial frame is detected in the PROFINET outputs, this frame is immediately sent on the serial link. For this, it is required to define the trigger for reading/sending frames in the head module TRANSPARENT MODE. VPGate PROFINET to serial user manual June 2017 PROCENTEC 18/104

19 For VPGate to function in the transparent mode: Insert the TRANSPARENT mode head module: Figure 14: Inserting the TRANSPARENT Mode head module Then adapt the different parameters of the transparent mode: Figure 15: TRANSPARENT Mode parameters VPGate PROFINET to serial user manual June 2017 PROCENTEC 19/104

20 Name Description Possible values NULL (0x00) SPACE (0x20) LF (0x0A) EOF delimiter (1) Defines how an end of frame will be detected CR (0x0D) CR LF User defined Length in 1st byte (3) On timeout (2) (3) User defined EOF ASCII code of the end of frame character (where EOF delimiter = User defined) 0 to 255 Add frames counter (4) Defines whether a frame counter is added at the start of the PROFINET input and output frames. Enabled Disabled Add and control CRC 16 Specifies whether a CRC16 should be controlled in the data received on a serial link and added at the end of the data sent to the device on the serial link. Enabled Disabled Timeout (in ms) (5) Time that enables detecting an end of frame when the EOF Delimiter parameter is set to On timeout. def: 1000 ms 0 to ms (1): If this parameter is set to User defined, the end of frame character taken into account is the one specified by the User defined EOF parameter. If it is set to on timeout, the reception timeout taken into account is the one defined in the configuration of the serial link. (2): If the parameter EOF delimiter is set to on timeout, only the frames received on the serial link will be detected on timeout. On the PROFINET side, the 1 st byte must is used to specify the length of the sent/received frame (refer to paragraph 3.4.1). This byte is not transferred on the serial link. (3): If the parameter EOF delimiter is set to length in 1st byte or to on timeout, the padding value is 0x00. (4): This counter is used as a trigger: If this parameter is activated, the 1 st byte of the PROFINET outputs must be a counter which is incremented each time data is available and is to be sent. The usable data starts from the 2 nd byte. If there is no counter, the frame is re-copied from the 1 st byte as soon as a change in the PROFINET outputs is detected. VPGate PROFINET to serial user manual June 2017 PROCENTEC 20/104

21 If this parameter is activated, the 1 st byte of the PROFINET inputs is incremented each time a new frame is received on the serial link. The usable data is copied after this counter. If there is no counter, the received frame is copied from the 1 st byte. Note: Each operating principle in the TRANSPARENT mode is described in detail in paragraph The Interframe Silence parameter in the TRANSPARENT mode: The Interframe silence parameter allows a waiting period between a reception and transmission of a frame: Figure 16: Interframe Silence in TRANSPARENT mode If no frame is detected, VPGate sends frames on the serial link without waiting for an inter-frame time. However if a frame is detected on RX, VPGate waits for the inter-frame time before sending the next frame Inserting and configuring modules in the TRANSPARENT mode In the transparent mode, the modules to be inserted depend on the maximum number of bytes that can be received or sent. If for example, a maximum of 128 bytes can be exchanged on the serial link, including sending and receiving, the modules "Input Bytes/128 bytes" and "Output Bytes/128 bytes must be inserted. VPGate PROFINET to serial user manual June 2017 PROCENTEC 21/104

22 Inserting modules: Figure 17: Inserting modules in the TRANSPARENT mode Up to 250 PROFINET input bytes and 250 PROFINET output bytes can be inserted. In the following examples, 128 input bytes and 128 output bytes are inserted. Please note that in the TRANSPARENT mode, the input or output modules must be adjoining. If you wish to insert one more Digital input/output module, then it must be inserted in the first or the last place. Operating principle Case in which the end of frame is detected using a specific character: In this example, the end of frame character is the ASCII CR code (0x0D). After receiving the 1 st byte on the serial link: If no byte is received during the timeout configured in the serial link configuration, an error is reported and the incomplete frame is not sent on PROFINET. If the received frame length is greater than the number of PROFINET input bytes and if the received frame is valid, an error is reported and the frame is truncated on PROFINET. If a change is detected in the PROFINET outputs: If there is an end of frame character in the frame, the data is sent on the serial link of the 1 st byte up to the end of frame character (included). Anything after that is ignored. VPGate PROFINET to serial user manual June 2017 PROCENTEC 22/104

23 Case in which the frame length is known: The 1 st byte must contain the number of bytes that follow. After receiving the 1 st byte on the serial link: If the expected bytes are not received after the timeout configured in the serial link configuration, an error is reported and the incomplete frame is not sent on PROFINET. If the received frame length is greater than the number of PROFINET input bytes and if the received frame is valid, an error is reported and the frame is truncated on PROFINET. If a change is detected in the PROFINET outputs: If the 1 st byte has a length greater than the number of PROFINET outputs, an error is reported and no data is sent. Case in which the end of frame is detected on a timeout: The 1 st byte of the PROFINET inputs indicates the number of bytes received. The 1 st byte of the PROFINET outputs must indicate the number of bytes to be sent. After receiving the 1 st byte on the serial link: In no byte is received during the timeout configured in the serial link configuration, the number of received characters is recorded in the 1 st byte of the PROFINET inputs, after which the received data is sent on PROFINET after this byte for the length. If the length of the received frame plus a length byte is greater than the number of PROFINET input bytes, an error is reported and the frame is truncated on PROFINET. If a change is detected in the PROFINET outputs: If the 1 st byte has a length greater than the number of PROFINET outputs, an error is reported and no data is sent. VPGate PROFINET to serial user manual June 2017 PROCENTEC 23/104

24 Trigger function of the frame counter: A frame counter, when activated, is added at the start of the PROFINET input and output frames. This counter is incremented for each new available frame. It is used to report the presence of a new received frame or to detect a new frame to be sent. Ci = Counter input Co = Counter output In this example, the length of the frames is known. The byte encoding the length in the PROFINET inputs and outputs is located at byte no. 2, after the counter. 3.5 Configuration in MODBUS Master mode To use VPGate in the MODBUS Master mode, follow the steps given below: Insert the MODBUS MASTER Mode head module: Figure 18: Inserting the MODBUS MASTER Mode head module Adapt the general parameters of the MODBUS MASTER Mode: Figure 19: General parameters of the MODBUS MASTER mode VPGate PROFINET to serial user manual June 2017 PROCENTEC 24/104

Operating principle: Figure 27: Operating principle in the MODBUS Master mode: Behaviour of the MODBUS Master according to PROFINET status The MODBUS Master of VPGate operates according to the PROFINET connection state. The values of data provided to Modbus slaves must be known during all the possible states of the PROFINET device. Three specific transitions are described here: Startup IO-Controller goes to STOP state (IO Producer Status data goes to BAD) Ethernet Link-down These transitions are described to ensure that the data provided by the VPGate MODBUS Master are always known. This is important when VPGate PROFINET is configured with output provided to MODBUS slaves. Startup: After receiving the modules configuration, VPGate MODBUS Master will try to execute the configured MODBUS scenario. At this state, the PROFINET connection is not yet finished, IO-Controlled IO Producer Status is bad and application ready is not yet transmitted so zeroed values will be provided to MODBUS salves. When IO-Controller IO Producer Status goes good, output are updated and provided to the MODBUS slaves. VPGate PROFINET to serial user manual June 2017 PROCENTEC 29/104

30 IO-Controller goes to STOP state (IO Producer Status data goes to BAD): When data provided by the IO-Controller are no longer good (IO Producer Status is bad), the VPGate MODBUS Master will keep sending the last good data it has received from the PROFINET IO-Controller. All Modbus scenarios will keep running, and the last good received data from PROFINET are provided to the MODBUS slaves. Ethernet Link-down: When the Ethernet link goes down, VPGate MODBUS Master will directly stop all the communication with Modbus slaves. Only last received values will be present in MODBUS slaves. 3.6 Configuration in the MODBUS Slave mode To use VPGate in the slave mode: Insert the MODBUS SLAVE Mode head module: Figure 28: Inserting the MODBUS SLAVE Mode head module Adapt the general parameters of the MODBUS SLAVE Mode: Figure 29: General parameters of the MODBUS Slave mode Name Description Possible values MODBUS protocol Selecting the type of encoding of information in MODBUS.

32 3.6.1 Inserting and configuring modules in the MODBUS Slave mode In the MODBUS Slave mode, the modules to be inserted depend on the number of inputs and outputs that need to be exchanged by the PROFINET controller. The entire VPGate exchange table is accessible on the MODBUS serial link end. In the read-only or write-only modes, a MODBUS master can directly access the VPGate data table, which is considered as a MODBUS register table in this case (4096 registers of which 2048 are available for exchanging input and 2048 for output data). The data is accessible after connecting to the PROFINET automaton: From the offset 0x0000 (0 in decimals): PROFINET inputs. From the offset 0x0800 (2048 in decimals): PROFINET outputs. In the slave mode, an OUTPUT REGISTER will be written by the PROFINET IO-Controller and read by the MODBUS Master. An INPUT REGISTER will be read by the PROFINET IO-Controller and written by the MODBUS Master. Example 1 The PROFINET IO controller wishes to read 64 bytes of data coming from MODBUS in VPGate. We thus insert a module with 32 registers in read-only mode Input Registers registers. These 64 bytes will be read on PROFINET cyclically. A MODBUS master must write the 32 registers from the offset 0x000 of VPGate (PROFINET input range). Example 2 The PROFINET IO controller wishes to write 16 bytes of data in order to make it accessible on the MODBUS end. We insert an output module with 8 registers Output registers 008 register. These 16 bytes will be cyclically written by the IO controller from the PROFINET. A MODBUS master can read the 8 registers by making a read request using the offset 0x0800 (2048 in decimals) in the VPGate MODBUS slave.

34 4. Diagnostic 4.1 Diagnostic on the UDP port Information about the configuration, parameterisation and status of the functioning of VPGate are sent via the UDP protocol. This information can be viewed using a tool that displays ASCII data received on the UDP port. The properties of the UDP link are: Port: (DBE016) Destination IP address: Broadcast on the IP network of VPGate (example: on a network). When switched on, the following header is sent: When the gateway connects to PROFINET, the physical parameters of the MODBUS link are displayed. The configured exchanges are then displayed. In the following example, 1 exchange on MODBUS MASTER is configured: Corresponds to a Read 001 register module configured to use the MODBUS 0x03 function on the slave 0x01 with a cycle time of 500 ms. VPGate PROFINET to serial user manual June 2017 PROCENTEC 34/104

35 If the MODBUS link is correctly established, no additional message is displayed. Otherwise, a message reports the encountered error. In the following example, the MODBUS slave mentioned in the configuration of scenario 1 no longer responds. In the above case, the TIMEOUT error message is repeated twice since the Retries if Timeout parameter of the VPGate hardware configuration was previously set to 2. When the third error occurs, an additional message is displayed, stating that a fault has occurred. When the gateway is disconnected from PROFINET, the following message is displayed. 4.2 PROFINET diagnostic VPGate generates alarms if there is a communication problem for any exchange configured in the MODBUS MASTER mode. For the PROFINET alarms to be active (they are active by default), the Diagnostic alarms parameter must be set to Checked : Figure 32: Activation of the Diagnostic alarms mode The diagnostic information can then be processed by the automaton and is explained to the operator in the online mode of the engineering tool (e.g. SETP7).

37 Name Description Possible values Disabled Digital Output Mode Defines the behaviour of the Digital output On PROFINET SF On serial link SF On PROFINET or serial link SF The relay is of the Normally Open (NO) type. The relay is thus open if there is no fault. If there is a fault, the relay closes. It remains closed until the fault is rectified. Note that if an output module is plugged into Digital Output, it is given priority over the command of the output relay if there is a fault. In the Disabled mode, the relay is not requested if there is a fault. In the On PROFINET SF mode, the relay will be closed if communication with the PROFINET IO controller is lost. In the On serial link SF mode, the relay will be closed if a fault is detected on the serial link (e.g. Timeout of the MODBUS slave, CRC error, Modbus function not supported by the slave, etc.) In the On PROFINET or serial link SF mode, the relay will be closed if communication with the IO controller is lost or when an error is detected on the serial link.

38 5. Digital inputs/outputs 5.1 Digital output There are 2 possible operating modes if the Digital output is connected: Diagnostic output, configured via the parameters of the VPGate head module Digital output module that can be controlled from PROFINET if the Digital Output module is used. Diagnostic output: The parameter of the Digital Output Mode head module is configured to On PROFINET SF or On serial link SF or On PROFINET or serial link SF and Digital Output is not plugged in. The relay contact is activated if a communication fault is detected in the selected mode. Digital output module: The Digital Output Mode parameter in the head module is set to Disabled and the Digital Output module is inserted in the configuration. The relay contact is run by the least significant bit of the byte of the Digital Output module. Figure 35: Inserting a Digital Output module 5.2 Digital input If the Digital input is connected and the Digital Input module is inserted: If the input is 1, the least significant bit of the Digital Input module is set to 1. If the input is 0, the least significant bit of the Digital Input module is set to 0. VPGate PROFINET to serial user manual June 2017 PROCENTEC 38/104

40 6. IP address configuration Since VPGate is a PROFINET IO device, its IP address is allocated by the IO controller of the PROFINET network via the DCP protocol. If the PROFINET connection is not established with an IO controller, the IP address of VPGate may be set manually using the DCP protocol via tools such as SIEMENS SIMATIC Manager or Primary Setup Tool. Moreover, for ease of access to the station, a default IP address ( ) may also be allocated via the switches on the front side of VPGate. 6.1 Configuration via the DCP protocol With the PROFINET configuration tool (e.g.: SIEMENS HW Config): Figure 37: Editing Ethernet stations 1. Selection of the station from the list of accessible PROFINET stations. The flashing functionality helps in distinguishing a particular device from several others of the same type by flashing the RUN indicator at a frequency of 4 Hz for VPGate. The selected station is identified by its MAC address. VPGate PROFINET to serial user manual June 2017 PROCENTEC 40/104

41 Figure 38: Selecting Ethernet stations 2: Definition of the IP parameters (IP address, subnet mask and optionally, the router address). 3: Validation of the parameters and transmission of data to VPGate. According to the configuration tool used, the IP configuration may either be temporary (reinitialised after being switched off) or persistent (saved in the non-volatile memory and reused after VPGate is switched on again). The IP parameters are always overwritten by the data sent by the IO controller to the PROFINET connection (refer to PROFINET standard): If this option is selected, the manually defined IP information will be overwritten when connected to the IO controller. Figure 39: Allocation of an IP address via the IO controller 6.2 Default configuration A switch enables resetting to a default configuration (@IP , mask ) when the VPGate Ethernet is switched on. The configuration takes place as follows: VPGate PROFINET to serial user manual June 2017 PROCENTEC 41/104

43 7. MRP redundancy 7.1 Functioning in the MRP Client MRP is a media redundancy management protocol. It can only be used with a ring topology. The principle is as follows: A Media Redundancy Manager (MRM) is selected on the network to open the ring and cyclically control the integrity of the ring. The other devices present on the ring are Media Redundancy Clients (MRC). MRM MRC MRC MRC Figure 41: Fault-free MRP redundant ring VPGate can be configured to integrate a MRP ring as a Client (MRC). 7.2 Configuration 2 1 Figure 42: Configuration in the MRP Client mode VPGate PROFINET to serial user manual June 2017 PROCENTEC 43/104

44 8. Modbus/TCP VPGate PROFINET integrates the MODBUS/TCP server and gateway functionality. This functionality is always active. 8.1 Operating principle In the read-only or write-only modes, a MODBUS/TCP client can directly access the VPGate data table, which is considered as a MODBUS register table in this case (65535 registers of which 4096 are available for exchanging input/output data). The data is accessible after connecting to the PROFINET automation: From the offset 0x0000: PROFINET inputs. From the offset 0x800: PROFINET outputs. Supported MODBUS functions: 1: Read coils 2: Read Discrete Inputs 3: Read Holding Registers 4: Read Input Registers 5: Write Single Coil 6: Write Single Register 7: Read Exception Status (reads the register at the offset 0x0000) 15: Write Multiple Coils 16: Write Multiple Registers 23: Read/Write Multiple Registers Figure 43: Data exchange in the MODBUS/TCP server mode This access is only possible if the UnitID field of the MODBUS TCP MBAP is set to a value greater than 247. If this value is less than or equal to 247, VPGate ETHERNET will function in the MODBUS/TCP gateway to serial mode. This UnitID field can normally be set by the MODBUS TCP client. The TCP port used is the standard port 502. VPGate ETHERNET can accept up to 3 simultaneous MODBUS/TCP connections. For more information about the MODBUS/TCP protocol, refer to the document - Modbus Messaging Implementation Guide [5]. VPGate PROFINET to serial user manual June 2017 PROCENTEC 44/104

45 8.2 Fault management If a corrupted frame is detected, the request is ignored and no response is sent to the MODBUS Master. If the frame received is correct but a protocol error is detected, a MODBUS exception is sent in response to the MODBUS/TCP Client: MODBUS exception code Description 0x01 0x02 Illegal function : the MODBUS function code is not supported. Illegal data address : the requested data address is not valid. 0x03 Illegal data value : the data contained in the request is erroneous (e.g.: number of registers to be read is greater than the maximum value defined by the function code). Table 1: MODBUS exceptions returned by the MODBUS/TCP server protocol For more information about MODBUS/TCP exceptions, refer to the document [4]. 8.3 MODBUS/TCP GATEWAY TO MODBUS SERIAL mode Operating principle VPGate ETHERNET may be used in the MODBUS/TCP gateway MODBUS serial mode. In this mode, MODBUS/TCP requests are converted into MODBUS serial requests and are sent on the serial link. On the other hand, the responses received from the serial link are converted into MODBUS/TCP responses. This functioning is only possible if the UnitID field of the MODBUS/TCP MBAP is set to a value less than or equal to 247. This UnitID field can normally be set by the MODBUS/TCP client. This functionality is available in the following cases: VPGate is not connected to a PROFINET network (as soon as it is switched on). Only when VPGate is connected to a PROFINET IO controller in the MODBUS MASTER Mode. Figure 44: Data exchange in the MODBUS/TCP Gateway to MODBUS serial link mode VPGate PROFINET to serial user manual June 2017 PROCENTEC 45/104

46 In this operating mode, the transmission time of the MODBUS messages is longer than in the internal exchange table access mode. The bandwidth configured on the serial link affects the response time of VPGate on the MODBUS/TCP end. It is possible for a MODBUS/TCP request to be considered to have no response (timeout) by a client when the transit time extends the delivery time of the message. In this case, the better option would be to increase the timeout parameter of the requests on the client. For more information about the MODBUS/TCP protocol, refer to the document - Modbus Messaging Implementation Guide [5] Fault management Given below is a list of faults related to the MODBUS/TCP Gateway to MODBUS serial mode and their probable causes: Error MODBUS 0x0A exception response GATEWAY PATH UNAVAILABLE to the MODBUS/TCP request MODBUS 0x0B exception response GATEWAY TARGET DEVICE FAILED TO RESPOND to the MODBUS/TCP request Another MODBUS exception response to the MODBUS/TCP request. Response to a MODBUS/TCP request when no request has been issued on the serial link end. Probable cause The Gateway mode is deactivated. MODBUS Master serial link protocol is deactivated. No response on the serial link end. Frame error detected on the serial link end response (CRC, length) The exception received on MODBUS TCP corresponds to the exception sent by the slave on the serial link end. The value of the UnitID field of the MBAP TCP header is greater than 247.

These WEB pages may be: Static HTML pages that have links to images, etc. Dynamic HTML pages that enable access to device data by using the JavaScript code and a specific API (set of functions) to interact with VPGate. HTML pages hosting JAVA applets that will be downloaded and run on the PC connected to the device and that also allow access to the device data via MODBUS/TCP requests, for example. The HTML pages, images, etc. may be placed anywhere and at any level of the file system Accessing data via personalised WEB pages This paragraph is only about accessing data via the CGI server of VPGate ETHERNET. The device data may also be accessed in read-only or write-only modes via any Internet browser. Two operating procedures may be used: Direct access to the referenced data table If field (address) is greater than 247, the request is interpreted as being meant for the VPGate internal data table: Figure 57: Direct access to the internal data table via a personalised WEB page VPGate PROFINET to serial user manual June 2017 PROCENTEC 58/104

59 Figure 58: Gateway mode via a personalised WEB page If field (address) is less than or equal to 247, the request is interpreted as being directly meant for a MODBUS slave device on the serial link. A MODBUS request is thus sent on the serial link and awaits a response. For this mode to function, the MODBUS Master serial link protocol must be activated (no PROFINET connection or DAP MODBUS MASTER plugged in). The MODBUS requests thus generated are inserted between the MODBUS requests configured on PROFINET. If a request arrives when a scenario is being executed, it is issued as soon as the ongoing scenario is completed An example of customised WEB pages Given below is an example of a customized WEB page provided with VPGate. It enables: browsing the submenus via tabs, periodically reading, in the Gateway mode, the temperature measured by a MODBUS serial device connected on VPGate, presenting a dynamic overview diagram of the system with a trend line and the system status, sending requests to read or write MODBUS registers to the device communicating on MODBUS serial.

The frame length provided in the answer of the MODBUS slave is not correct. The function code received in the query is not an allowable action for the slave. This may be because the function code is only applicable to newer devices, and was not implemented in the unit selected. It could also indicate that the slave is in the wrong state to process a request of this type, for example because it is unconfigured and is being asked to return register values. Check the slave device documentation for more details about function codes that are supported. The data address received in the query is not an allowable address for the slave. More specifically, the combination of register address and transfer length is invalid. For a controller with 100 registers, the PDU addresses the first register as 0, and the last one as 99. If a request is submitted with a starting register address of 96 and a quantity of registers of 4, then this request will successfully operate (address-wise at least) on registers 96, 97, 98, 99. If a request is submitted with a starting register address of 96 and a quantity of registers of 5, then this request will fail with Exception Code 0x02 Illegal Data Address since it attempts to operate on registers 96, 97, 98, 99 and 100, and there is no register with address 100. Check the slave device documentation for more details about limitation of register address range. VPGate PROFINET to serial user manual June 2017 PROCENTEC 64/104

This indicates a fault in the structure of the remainder of a complex request, such as that the implied length is incorrect. It specifically does NOT mean that a data item submitted for storage in a register has a value outside the expectation of the application program, since the MODBUS protocol is unaware of the significance of any particular value of any particular register. An unrecoverable error occurred while the slave was attempting to perform the requested action. Specialized use in conjunction with programming commands. The slave has accepted the request and is processing it, but a long duration of time will be required to do so. This response is returned to prevent a timeout error from occurring in the master. The master can next issue a Poll Program Complete message to determine if processing is completed. Specialized use in conjunction with programming commands. The slave is engaged in processing a longduration program command. The master should retransmit the message later when the slave is free. Specialized use in conjunction with function codes 20 and 21 and reference type 6, to indicate that the extended file area failed to pass a consistency check. The slave attempted to read record file, but detected a parity error in the memory. The master can retry the request, but service may be required on slave device. Specialized use in conjunction with gateways; indicates that the gateway was unable to allocate an internal communication path from the input port to the output port for processing the request. Usually means that the gateway is incorrectly configured or overloaded. Specialized use in conjunction with gateways; indicates that no response was obtained from the target device.

Check that the slave is online, correctly connected and that its serial link configuration corresponds to the one used with the master. The address received in the response of the slave is not corresponding to the one used in the original query sent by the master. This means that the slave misunderstood the original address. The function received in the response of the slave is not corresponding to the one used in the original query sent by the master. This means that the slave misunderstood the original function code. In case of a write request, the data received in the response of the slave is not corresponding to the one used in the original query sent by the master.

67 Appendix B: MODBUS frame formats The MODBUS functions 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x0F, 0x10 and 0x17 are supported by VPGate. The format of each function is detailed with the help of an example for the ASCII and RTU mode. The CRC (MODBUS RTU) or LRC (MODBUS ASCII) bytes are mandatory. MODBUS RTU uses 8 bit data coding. MODBUS ASCII uses 7 bit data coding. Reminder: The address of a MODBUS register must be different from the number of the MODBUS register. For example, the register 1 is at the address 0x0000. The address of the register is what is used in a MODBUS frame. When the scenarios are configured, the address of the MODBUS register must also be used. Function 1 (0x01) This function enables reading the status of several Booleans (coils or Discrete outputs). The broadcast is not supported. The number of Booleans to be read simultaneously with VPGate is limited to 2000 (16 bits x 125 registers).

VPGate PROFINET MODBUS manages the following exceptions: Exception code Name Description 01 ILLEGAL FUNCTION This exception is returned by the slave if the master uses a function that the slave does not recognise. VPGate MODBUS only manages the functions 1, 2, 3, 4, 5, 6, 7, 15, 16 and ILLEGAL DATA ADDRESS This exception is returned if the master attempts to access an inaccessible MODBUS register. For example, VPGate is configured such that it has 10 registers in read-only mode (address 0 to 9) and 10 registers in write-only mode (address 0 to 9). An error is thus reported if the master tries to access register 20. This error also occurs if, for example, with a function 3, the master tries to read 20 registers from the register 1 (address 0). 03 ILLEGAL DATA VALUE This exception is returned if the master attempts to write data that the slave cannot accept. For example, with the function 5, the only possible data is 0x0000 and 0xFF00. In all other cases, the exception function 3 is sent back.

Format of the exception frame: This exception frame is an example of a frame received in response to a function 6. The exception occurred because the master attempted to access an unauthorised register. The MODBUS function codes are 7-bit (codes 1 to 127).

85 Appendix C: API, CGI, Javascript The web server offers a CGI interface which enables processing HTTP requests that are meant for the VPGate application. When the CGI requests are received by the web server, they are interpreted and then a HTTP response is sent back to the client. Only the POST method can be interpreted by the CGI server. The HTTP client must use it to interface with the CGI server. Unlike the GET method in which the variables are sent in the URL, POST allows directly sending the variables in the body of the HTTP request. The CGI server carries out a filtering process when it receives the requests. Only those requests that have the URL /UE/FLASH0/device will be processed by the CGI server. Requests that have a different URL will be ignored. The CGI messages are sent in the form of a character string: Definition of the format of the requests CGI requests must have a format comprising the following fields: Field Syntax Acceptable values Description Address A=Xh 0 to 247 Gateway mode.

86 Digital values are always expressed in hexadecimals format in CGI requests/responses. E.g.: for a request to read a register in the exchange table at offset 0: "A=F8&F=3&O=0&Q=1&V=0" (&: separator) E.g.: for a request to write the value 1Fh in the register, at the offset Fh, in a remote slave at the address 1. "A=1&F=10&O=F&Q=1&V=1F" When writing multiple registers, the values must be separated with the character ':' (two dots) in the field of the data to be written "V=". E.g.: writing of 5 registers, from the offset 2000 of a slave at the address 12. Offsets Decimal values Hexadecimal values 2000 / 0x70D 0 0x x x x4B x64 "A=C&F=10&O=70D&Q=1&V=0:19:32:4B:64" Comment: The character ':' must be added between each value. If the character ':' is added after the last value to be written, the frame will nevertheless be considered valid. Definition of the format of the responses The responses coming from the CGI interface contain the following fields: Field Syntax Acceptable values Description Address A=Xh 0 to 247 Gateway mode.

JAVASCRIPT FUNCTION LIBRARY JavaScript scripts are used to send CGI requests via the Web server. The function library provided is in the form of the file ag_cgi_asynchrone.js. It contains functions that enable creating and sending requests and then receiving responses. To include the synchronous library, the following line must be added in the tag <head><\head> of the home.html page: <script type="text/javascript" language="javascript" src="./js/ag_cgi_asynchrone.js" /> The directory called js, which contains ag_cg_asynchrone.js, can be found at the same level as the home.html file in the file system.

89 Communication object: An object called ag_commobject that includes all the necessary fields is used to create requests. Once the request is sent, they will be updated automatically on receiving the response. Given below is the description of the ag_commobject class: ag_commobject - Address (integer): address of the slave - Function (integer): function used - Offset (integer): offset of the data - Quantity (integer): quantity of data - Data[] (table of integers): contains the values that are read or to be written - Exception (integer): exception code - WaitAnswer (Boolean): flag reporting that a response is being awaited from the CGI server + comm() (constructor): enables creating a communication object + init() (method): initialises all fields to 0 and wipes the table + getaddress() (accessor): returns the value of the Address property + setaddress(addr) (accessor): attributes the value addr to the Address property + getfunction() (accessor): returns the value of the Function property + setfunction(func) (accessor): attributes the value func to the Function property + getoffset() (accessor): returns the value of the Offset property + setoffset(offset) (accessor): attributes the value offset to the Offset property + getquantity() (accessor): returns the value of the Quantity property + setquantity(qty) (accessor): attributes the value qty to the Quantity property + getdata(index) (accessor): returns the value of the Data table to the given index + getalldata() (accessor): returns the Data table + adddata(data) (accessor): adds the value data later in the Data table + setdata(arraydata) (accessor): attributes the past table in the Data parameter VPGate PROFINET to serial user manual June 2017 PROCENTEC 89/104

90 ag_commobject + getexception() (accessor): returns the value of the exception property + setexception(ex) (accessor): attributes the value Ex to the exception property + getwaitanswer() (accessor): returns the value of the WaitAnswer flag + setwaitanswer(bool) (accessor): attributes the value bool to the exception property The communication object is a global variable of the ag_cgi_asynchrone.js file. It will be known and usable in all other JavaScript files included in this page. Functions: The basic functions of the asynchronous mode function differently, especially the request creation function. As a result, waiting for the response to the request in the asynchronous mode does not block the process. The script continues running during the time for which the request is processed by the CGI server. A callback function mechanism has been implemented to inform about the arrival of the response. CreateRequest (addr, MDBfunction, offset, qty, value, callback) To create a request, the function CreateRequest() is used, which accepts the fields of the request and a pointer on a callback function as parameters. As the first step, a XMLHttpRequest object is created: ag_httprequest = new XMLHttpRequest(); // Construction of the object The open() method of this object enables creating a HTTP request by specifying the method used, the URL and the mode: ag_httprequest.open( "POST", // Method "/UE/FLASH0/device", //URL true); // Asynchronous mode Only the POST method can be used, with a specific URL ( /UE/FLASH0/device ), to interface with the CGI server. The send() method of this object is used to send the request. The parameters define the character string that will be sent in the body of the request. The CreateRequest() function returns to 1 if it is terminated correctly; otherwise, it returns to 0 to indicate that the CGI server is busy. The response to the request is detected using the onreadystatechange event of the XMLHttpRequest object. This event is called when the loading status of the data changes. VPGate PROFINET to serial user manual June 2017 PROCENTEC 90/104

91 ag_httprequest.onreadystatechange = function() { if(ag_httprequest.readystate == 4) { ag_commobject.setwaitanswer(false); callback(ag_httprequest.responsetext); } } // Function on loading // Ready response // Processing complete // Callback call When the loading status is complete, it indicates that the response has been received in its entirety. The callback that will process the received data is called. ReadRequest (addr, MDBfunction, offset, qty, callback) This function enables sending a read request. As parameters, it receives the fields (address, function, etc.) of the request to be created and calls the CreateRequest() function with 0 as the data value parameter. The ReadRequest() function returns to 1 if the operation succeeds; otherwise it returns to 0 to indicate that the CGI server is busy. WriteRequest (addr, MDBfunction, offset, qty, value, callback) This function enables sending a write request. As parameters, it receives the fields (address, function, etc.) of the request to be created and calls the CreateRequest() function. The ReadRequest() function returns to 1 if the operation succeeds; otherwise it returns to 0 to indicate that the CGI server is busy. GetAnwserHeader (response) This function enables storing the values of the response header (address, function, offset, quantity, exception code) in the communication object. As parameters, it accepts the character string corresponding to the body of the response. In the ag_cgi_asynchrone.js file, these functions are used by other functions that have a defined role (reading multiple registers, writing multiple registers, etc.). The use of these functions should be preferred in the personalised WEB pages: ReadSingleRegister (ag_commobject, usercallback) This function enables reading a single register. The parameters of the function are: ag_commobject.address: address of the slave in decimals. ag_commobject.offset: offset of the register to be read in decimals. usercallback: pointer on a JavaScript function of the user, to be executed after the reception of the response. The ReadSingleRegister() function returns: 1 if it is terminated successfully. 0 if the CGI server is busy. -1 if the data set in the parameters is incorrect (a dialogue box alerts the user and the communication object is reset to zero). VPGate PROFINET to serial user manual June 2017 PROCENTEC 91/104

92 After receiving the response, the communication object is updated with the received data. Then, the user callback is called. WriteSingleRegister (ag_commobject, usercallback) This function enables writing a single register. The parameters of the function are: ag_commobject.address: address of the slave in decimals. ag_commobject.offset: offset of the register to be written in decimals. ag_commobject.data[0]: 1 st case of the table containing the value to be written. usercallback: pointer on a JavaScript function of the user, to be executed after the reception of the response. The WriteSingleRegister() function returns: 1 if it is terminated successfully 0 if the CGI server is busy -1 if the data set in the parameters is incorrect (a dialogue box alerts the user and the communication object is reset to zero). After receiving the response, the communication object is updated with the received data. Then, the user callback is called. ReadMultipleRegisters (ag_commobject, usercallback) This function enables reading multiple consecutive registers. The parameters of the function are: ag_commobject.address: address of the slave in decimals. ag_commobject.offset: offset of the 1 st register to be read in decimals. ag_commobject.quantity: quantity of the registers to be read. usercallback: pointer on a JavaScript function of the user, to be executed after the reception of the response. The ReadMultiplesRegisters() function returns: 1 if it is terminated successfully 0 if the CGI server is busy -1 if the data set in the parameters is incorrect (a dialogue box alerts the user and the communication object is reset to zero). After receiving the response, the communication object is updated with the received data. Then, the user callback is called. WriteMultipleRegisters (ag_commobject, usercallback) This function enables writing multiple consecutive registers. The parameters of the function are: ag_commobject.address: address of the slave in decimals. ag_commobject.offset: offset of the 1 st register to be written in decimals. ag_commobject.quantity: number of the registers to be written. ag_commobject.data[]: contains the values to be written. usercallback: pointer on a JavaScript function of the user, to be executed after the reception of the response.

93 The WriteMultipleRegisters() function returns: 1 if it is terminated successfully. 0 if the CGI server is busy. -1 if the data set in the parameters is incorrect (a dialogue box alerts the user and the communication object is reset to zero). After receiving the response, the communication object is updated with the received data. Then, the user callback is called. ReadSingleBit (ag_commobject, usercallback) This function enables reading a single bit. The parameters of the function are: ag_commobject.address: address of the slave in decimals. ag_commobject.offset: offset of the bit to be read in decimals. usercallback: pointer on a JavaScript function of the user, to be executed after the reception of the response. The ReadSingleBit() function returns: 1 if it is terminated successfully. 0 if the CGI server is busy. -1 if the data set in the parameters is incorrect (a dialogue box alerts the user and the communication object is reset to zero). After receiving the response, the communication object is updated with the received data. Then, the user callback is called.
