10 hapter 1: Getting Started Introduction Overview of this Publication Modbus is one of the most popular communication protocols in the automation industry because it supports both traditional RS-// devices and newly developed industrial Ethernet devices. Many industrial devices, such as PLs, HMIs, instruments and meters use Modbus as their standard communication protocol. However, the Modbus protocols running over serial and Ethernet are so different that a communication gateway is needed as a bridge for integrating devices from these two networks. The M-GTEWY is a Modbus TP (Ethernet) to Modbus RTU (Serial) Gateway which provides the necessary bridge to connect Modbus RTU (Serial) products to Ethernet LNs. The Modbus TP side of the Gateway functions as a TP Server (slave) while the Modbus RTU side functions as a serial lient (master). The serial side physical interface is RS-/ or wire so up to 1 Modbus RTU devices can be accessed by a Modbus TP lient device (up to 1 simultaneous connections). The actual number of Modbus RTU slaves will depend on their individual transceiver loads.

23 hapter : Installation, Wiring and onfiguration Safety Guidelines Warning: Providing a safe operating environment for personnel and equipment is your responsibility and should be your primary goal during system planning and installation. utomation systems can fail and may result in situations that can cause serious injury to personnel or damage to equipment. o not rely on the automation system alone to provide a safe operating environment. You should use external electromechanical devices, such as relays or limit switches, that are independent of the PL application to provide protection for any part of the system that may cause personal injury or damage. Every automation application is different, so there may be special requirements for your particular application. Make sure you follow all national, state, and local government requirements for the proper installation and use of your equipment. Plan for Safety The best way to provide a safe operating environment is to make personnel and equipment safety part of the planning process. You should examine every aspect of the system to determine which areas are critical to operator or machine safety. If you are not familiar with control system installation practices, or your company does not have established installation guidelines, you should obtain additional information from the following sources. NEM The National Electrical Manufacturers ssociation, located in Washington,.. publishes many different documents that discuss standards for industrial control systems. You can order these publications directly from NEM. Some of these include: IS 1, General Standards for Industrial ontrol and Systems IS, Industrial Systems IS, Enclosures for Industrial ontrol Systems NE The National Electrical ode provides regulations concerning the installation and use of various types of electrical equipment. opies of the NE Handbook can often be obtained from your local electrical equipment distributor or your local library. Local and State gencies many local governments and state governments have additional requirements above and beyond those described in the NE Handbook. heck with your local Electrical Inspector or Fire Marshall office for information.

25 hapter : Installation, Wiring and onfiguration M-GTEWY onfiguration The M-GTEWY supports 1 Modbus RTU nodes on the serial side. The RS- specification supports up to devices before a repeater device is required. Proper cabling and termination is required. For RS- -wire installations, a cable with the proper shielding and impedance should be used such as a elden model. For RS- wire installations, a cable such as the elden model should be used. 10 ohm resistor should be used for termination on each end of the network as shown in the previous wiring diagrams. The GTEWY module has a termination resistor pre-installed so only one resistor needs to be added to the opposite end of the network away from the Gateway module. The M-GTEWY module supports up to 1 simultaneous Modbus TP connections. The M-GTEWY s TP listening port is the standard Modbus TP port 0 (not configurable). One of the major features of the M-GTEWY module is the utomatic Read function. This feature utilizes the idle time of the module while it is waiting for Ethernet requests. The utomatic Read function can be configured to poll specific Modbus data points of the serial nodes and place that data into a local data buffer. If a Modbus Ethernet request comes in for one of those data points, the M-GTEWY module will immediately respond with the data from local buffer and thereby respond much faster than it would if it had to generate a new serial request. See hapter for more information. The factory IP setting of the M-GTEWY module is to retrieve an IP address via HP. In order to see what IP address has been assigned and/or to change that setting the NetEdit software tool will be required to discover and configure the M-GTEWY TP/ IP settings. NetEdit is a free tool that is accessible at utomationirect s website or HOST engineering s website ( NOTE: NetEdit version. or later is required to support M-GTEWY M-GTEWY onfiguration continued on the next page M-GTEWY-USER-M Hardware User Manual, 1st Ed.

26 hapter : Installation, Wiring and onfiguration NetEdit onfiguration Using NetEdit is very simple. Once the software has been installed, follow the steps below to configure the settings of your M-GTEWY module. Start the software. It will scan automatically when you start it but if your M-GTEWY is inaccessible at the point of starting the software, you can press the Scan Network button at the top to make it scan again once the M-GTEWY has become accessible. NOTE: If you are unable to see the M-GTEWY... 1) If your P has more than one NI (Network Interface ard), e.g. a wireless and a wired, then you may need to either disable the NI(s) you are not using, or re-prioritize them such that the NI you are using is top priority. ) Verify the Network Interface on your P is functioning properly ) Verify all connections between the P and the M-GTEWY are properly made ) isable your firewall or open TP port to allow NetEdit. ) NetEdit version. or later is required to support M-GTEWY. In the Main window, double click on the M-GTEWY module that you want to configure. Select Use the following IP settings. Type in the settings that are compatible with your network and press the OK button and the M-GTEWY module s IP settings are now configured M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev. E 0/1 -

27 hapter : Installation, Wiring and onfiguration fter the M-GTEWY module s IP settings have been configured to be compatible with the subnet of your P, you can open Internet Explorer (or the Web browser of your choice) and continue the configuration for your application. You can also right click on the M-GTEWY in the main NetEdit window and choose Start Web based config to start your default Web browser with the correct IP address pre-configured for you. Function odes Supported The function codes supported by the M-GTEWY differ based upon whether the target from the Modbus lient is the M-GTEWY directly by utilizing the Gateway Modbus I and the utomatic Read function or direct access to a Modbus serial slave by specifying the Unit I of the Modbus Slave node itself. Target = M-GTEWY Module (using Gateway Modbus I and utomatic Read Function): Function ode 1 (Read oils 0xxxxx) Function ode (Read Input its 1xxxxx) Function ode (Read Holding Registers xxxxx) Function ode (Read Input Registers xxxxx) Function ode (Read iagnostics <Read Query ata Function>) Target = M-GTEWY Modbus Slave Node (using Unit I of Slave Node): ny function code supported by the Modbus Slave device Log Modbus/TP and/or RTU requests to SMTPViewer vailable in firmware 1.0. and later Using the SMTPViewer (download from HostEng.com and install it in the \HPTools folder), you can see the TP and RTU requests that are being processed by the M-GTEWY. This logging feature will only send packets to the P that requested the logging; therefore it is not using broadcast packets, and each Gateway can only log data to 1 P at a time. To use logging, connect to M_GTEWY with SMTPViewer (UP only; port 0x) and issue the following command: Log [req] [rsp] [rtu] [tcp] [dev #] [raw] req = Log requestsrsp = Log responsesrtu = Log RTU transactionstcp = Log TP transactionsraw = Show raw bytes instead of decoding transactionsdev # = Ex dev 1 would show only transactions for device 1 For example, to see all Modbus/RTU transactions (requests and responses) to/from device 1 in a decoded form, the command is: Log rtu req rsp dev 1 The command log by itself defaults to log req rsp rtu tcp which will show all requests and responses for all devices in a decoded form. ll forms of the log command toggle from on to off, so you can issue the same command again to turn logging off.

41 hapter : utomatic Read Feature utomatic Read Feature The utomatic Read Feature allows the M-GTEWY module to utilize some of the idle time that usually occurs between Modbus TP requests from the lient device. Note that this feature only allows the reading of data from the serial devices and not writing to them. Up to 1 automatic read requests can be configured M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev. E 0/1 -

42 hapter : utomatic Read Feature The M-GTEWY module can be assigned a Modbus Node address that corresponds with the Unit I number that is sent within the Modbus TP header that is typically used to target a Modbus RTU node that is on the serial side of the M-GTEWY. Therefore, the Node number that is assigned to the M-GTEWY module should be unique from any Modbus RTU nodes on the serial network. The utomatic Read function reads the specified registers, bits or coils from the Modbus RTU nodes and places that data into the specified M-GTEWY addresses that can be retrieved on the Ethernet side by specifying the M-GTEWY s Modbus address in the Unit I field of the Modbus TP client request. n example is shown below: Situation 1: Modbus TP lient device sends a request for a device not configured in the utomatic Read table. This will, in turn, generate a fresh new request on the serial side of the M-GTEWY module. Modbus TP lient device Memory To Read - Holding Regs.

This can be advantageous if the Modbus TP lient is a device that is busy doing numerous other tasks, such as a PL M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev. E 0/1 -

47 hapter : utomatic Read Feature dditional Optimization n additional method of optimization is used in the M-GTEWY. If a request is sent to the M-GTEWY from the Modbus TP lient targeted at a Node number and starting address that is equivalent to an entry in the utomatic Read table, the M-GTEWY will treat the request as if it had been targeted at the M-GTEWY Modbus address and will respond from its local data cache since the data is the same. Shown below are some more detailed explanations of the different fields that can be configured in the utomatic Read Function table. Memory to Read: There are options: 0 Unused Entry = isables this entry in the table. 1 oils = onfigures this entry to read Modbus oils (Read/Write bits). iscrete Inputs = onfigures this entry to read Modbus Input its (Read Only bits). Holding Regs = onfigures this entry to read Modbus Holding Registers (Read/Write 1 bit registers). Input Regs = onfigures this entry to read Modbus Input Registers (Read Only 1 bit registers). Slave Number: The network address of the Modbus RTU device to be read on the serial network. RTU Start ddress: The starting address (based at 0) to be read in the targeted Modbus RTU device on the serial network. Number of Elements: The Number of elements to read from the targeted Modbus RTU device on the serial network. If the Read is from oils or iscrete Inputs, the number specified will be the number of bits from If the Read is from Holding or Input Registers, the number specified will be the number of words (1 bit) from 1-1. Gateway Memory ddress: The starting address in the GTEWY module s local data cache to place the data that has been read from the Modbus RTU device on the serial network. Gateway Modbus ddress: isplays the Modbus address that the GTEWY module has been configured for (done in the Gateway Modbus I section of the home page). uto ssign Gateway ddresses: Selecting this option will allow the configuration software to automatically choose the best local addresses to place the data that has been read from the Modbus RTU devices. When the uto ssign Gateway ddresses option is NOT selected, care must be taken so the data from different utomatic Reads doesn t overlap in the Gateway s internal memory. If you specify an utomatic Read that will create overlapping data, the value in the Gateway Memory ddress field for that Read will be red. y default the Gateway will store the data from the individual automatic reads for the same memory types in consecutive locations in the Gateway s internal memory. Storing this data in consecutive data locations in the Gateway s internal memory allows reads to be optimized into as few requests as possible M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev.

48 hapter : utomatic Read Feature There are several different ways of addressing when communicating to Modbus devices. The method of specifying a Function ode and offset that is utilized in the utomatic Read function is a very common way. nother way that is very common and is seen often in utomationirect products is the use of the Modicon style addressing. This method employs a PL style address that contains a Modbus memory type in the highest digit of the address followed by the offset from 1. table is provided below that shows comparable addresses for both of these addressing styles. *Modbus Function Type ddress Range Equivalent Modicon Style ddressing Number of Elements 1. oils iscrete Inputs Holding Regs Input Regs * NOTE: Memory to Read column on Setup utomatic Reads web page utomatic Read Status ata vailable in firmware 1.0. and later The final selection on this page is the Status ata (Holding Register) ddress which allows the user to map a data area into the Gateway s Modbus Holding Register memory which will report the health of each of the automatic read operations. These 1 consecutive Holding Registers area can then be read from the Modbus Gateway (using the Gateway Modbus ddress as Unit I in the MRX instruction) to monitor the utomatic reads by the Modbus/ TP lient. lick the show status data format link to display a page that explains the layout of the data.
