9 Overview Overview The model 5905 Ethernet gateway converts RS-232/485 Modbus communication into Modbus/TCP on Ethernet. Two packaging versions are available the DINrail mountable Model 5905 which is used with SCADAPack controller; and the 5905SA which is used with personal computers and other RS-232/485 equipment. The model 5905SA is powered using an AC adapter. Applications include in-plant I/O and connectivity between SCADAPack and operator workstations, other PLC devices, and SCADA systems communication, using standard Modbus. The SA version may be used to tie in other devices, which use Modbus, such as PID controllers, Variable Frequency Drives (VFD), and UPS power systems. Support for RS-232 using RTS/CTS handshaking, allows the 5905 to be used as a gateway between Ethernet LAN and commonly used half-duplex SCADA communications media. Examples of devices which often require half-duplex support include the 5902 Bell 202 modem, radio modems, and various other halfduplex modems. The 5905 gateway allows interfacing of multiple or dualredundant host computers that need to be able to communicate to SCADA systems over a single communications channel. Multi-drop communication over RS-485, or half-duplex modems and radios, allows up to 255 Modbus slave devices to be connected to a 5905 Ethernet gateway by configuring the gateways with their IP addresses, and at the master end, define which Modbus slave stations can be found at each 5905 slave gateway. Up to 255 Modbus slaves can be connected to each gateway, and up to 8 TCP/IP connections are supported by each Document (Version ) 5/19/2011 9

10 Installation Installation The 5905 Ethernet Gateway is available in two standard versions, the model 5905 and the model 5905SA. The model 5905 is a standard 5000 module that connects to the system I/O Bus as an integrated part of a Control Microsystems system. The model 5905SA is a stand-alone version of the 5905 and is used with other devices such as personal computers. Both versions of the modem are identical in every respect except that the 5905SA is powered using a 9VDC AC adapter and has rubber feet for desktop mounting.

Refer to Figure1: 5905 Module Layout for the location of these connectors. The RS-232 serial communication port, labeled P4, is a 9 pin, D-sub-miniature connector, DE-9S, configured as a DTE (Data Terminal Equipment). Refer to section 0-RS-232 Serial Port for more information. Document (Version ) 5/19/

11 RS-232 Serial Port Installation The RS-485 serial communication port, labeled P5, is a 5 position removable terminal block. This terminal block supports 2 or 4 wire RS-485 wiring. Refer to section 0-RS-485 Port for more information. The Ethernet connection is terminated at the RJ-45 modular jack labeled P3. The RJ-45 modular jack pin-out is compatible with standard Ethernet cables. See section 0-Ethernet Connection for more information. The 9VDC AC adapter connection, labeled P6, is used with an AC Adapter available from Control Microsystems. This connection is used with the 5905SA module only. See section SA Power Connection for more information. The RS-232 port is a 9-pin D-sub-miniature connector (DE-9P) configured as Data Terminal Equipment (DTE).

12 Installation Pin Type Description Pin 7 RTS Pin 8 CTS 5905 Connection to DTE Output Input This pin is a MARK if full-duplex operation is selected for the port. This pin is set to a MARK just before and during transmission of data if half-duplex operation is selected. This pin is set to a SPACE when no data is being transmitted. A MARK level is required for the communication port to transmit data. When the attached device does not provide this signal, the controller keeps the line at a MARK. When the attached device does provide this signal, it sets CTS to MARK to allow the 5905 module to transmit data. Pin 9 NC The 5905 may be powered from pin 9 of the RS-232 connector, P4. There are a number of restrictions with respect to the 5VDC tolerance and fuse considerations. This feature may not be available on some of the initial production 5905 modules. Contact Control Microsystems Technical Support for further information when using this method of powering the 5905 module. The serial cable that is provided with the 5905 module is suitable for connecting the module to a DTE (Data Terminal Equipment) device such as a SCADAPack controller. Other DTE devices such as a personal computer may require a longer serial cable. This type of cable is commonly referred to as a null modem or computer to computer cable.

13 Installation RS-232 wiring requires shielded cable. The shield should be connected to chassis ground at one end of the cable only. The DE-9 connector shell is a good ground point. A maximum cable length of 50ft (15.2m) is allowed. Improperly shielded cable may result in the installation not complying with FCC or DOC radio interference regulations. RS-485 Port The RS-485 port transmits and receives differential voltages to other RS-485 devices. The RS-485 specification allows a maximum of 32 devices. A maximum cable length of 4000 feet (1200 m) terminated at each end is recommended. The RS-485 port has a 5 position removable terminal block for connections to the RS-485 network. Figure 4: 5905 RS-485 Terminal Block Connection, P5 and Table 2: RS-485 Connections describe this connector. The signal grounds of the RS-485 devices are not connected together but instead are referenced to their respective incoming electrical grounds. The grounds of the RS-485 devices need to be within several volts of each other. The RS-485 port operates in two or four wire mode. Four jumpers need to be set for the correct operation of the RS-485 port; Rx Term, J5; Tx Term, J6; RS232/485, J8 and 2Wire/4Wire, J10. The correct settings of these and other jumpers can be found in chapter Configuration Jumpers Tx -- + Rx -- Figure 4: 5905 RS-485 Terminal Block Connection, P5 A description of each terminal block signal for connector P5 is shown in Table 2: RS-485 Connections.

Other RS- 485 Device RX + RX TX + TX RS-485 network 4000 feet (1200 m) maximum length 5905 RX + RX TX + TX Last station in network requires terminations. Termination Resistors Ethernet Connection Figure 6: RS-485 Field Wiring Two Wire Mode Termination resistors are required on the first and last station on the RS-485 wire pair. Other stations should not have termination resistors. Resistors for receiver and transmitter termination are pre-installed on the 5905 module. Refer to chapter Configuration Jumpers for instructions on connecting the termination resistors. The 5905 module uses a traditional termination scheme with one 120-ohm resistor across the line. Special receivers have been used such that the received data will be in an idle state for the following conditions on the RX pair: open inputs, terminated inputs, and shorted inputs. This termination scheme may not be compatible with other RS-485 devices. RS-485 receivers that cannot tolerate a differential input voltage of 0 volts (line terminated but not driven) should be terminated with resistors that bias the line to a known state during these conditions. The Ethernet network connects to the RJ-45 modular jack labeled P3. The RJ-45 jack mates with 8-pin connector and cable assemblies common to Ethernet 10Base-T applications. Pins 1,2,3 and 6 are used. Pins 4,5,7, and 8 are not used. See Figure 7: 5905 Ethernet RJ-45 Connection for pin connections. Document (Version ) 5/19/

19 Operation Operation Application Examples Modbus/TCP Access to Modbus RTU When it comes to planning data communication for open, multi-vendor industrial control systems, Modbus is the undisputed first choice of end users and integrators alike. The Modbus protocol defines how a Master device polls one or more Slave devices to read and write data in real-time with RS-232, RS-422, or RS-485 serial data communication. Modbus/TCP is an extension of serial Modbus, which defines how Modbus messages are encoded within and transported over TCP/IP-based networks. Modbus/TCP is just as simple to implement and flexible to apply as serial Modbus. Complete information for Modbus/TCP and serial Modbus may be found on-line at The following section describes some of the applications in which the 5905 Ethernet Gateway may be used in a Modbus/TCP network. The model 5905 Ethernet gateway allows Modbus RTU, or Modbus ASCII, master and slave stations to communicate using an Ethernet LAN. The 5905 converts RS-232/485 Modbus serial communication into Modbus/TCP on Ethernet. In the application shown in Figure 8: Modbus/TCP Access to Modbus RTU a PC is running a Modbus/TCP host MMI application and is connected to the Ethernet LAN using an internal Ethernet port. The host PC can communicate with any number of Modbus/TCP slave stations. Also connected to the Ethernet LAN is a SCADAPack master station using a 5905 Ethernet gateway module. The SCADAPack and the host PC are each polling the RS-485 network of SCADAPack controllers located at Site C. Figure 8: Modbus/TCP Access to Modbus RTU Document (Version ) 5/19/

20 Multiple Access to Modbus RTU Operation The 5905 Ethernet gateway supports multiple master stations communicating with single or multiple slave stations across an Ethernet LAN. The 5905 module supports up to 8 Modbus/TCP connections per module. The configuration shown in Figure 9: Multiple Access to Modbus RTU has three Modbus/TCP master stations communicating with a single Modbus slave station. Two of the master stations shown are PCs running Modbus/TCP applications and connected to the Ethernet LAN using internal Ethernet ports. The third master station is a SCADAPack controller connected to the Ethernet LAN using a 5905 Ethernet gateway module. The slave station is a SCADAPack controller connected to the Ethernet LAN using a 5905 Ethernet gateway module. Figure 9: Multiple Access to Modbus RTU Modbus/RTU RS-485 Bridging Through Ethernet Support for RS-485, two or four-wire, serial communication allows the 5905 modules to be used as a gateway between a PC running a host Man Machine Interface (MMI) application and multi-drop RS-485 networks using an Ethernet LAN. In the example shown in Figure 10: Modbus/RTU RS-485 Bridging Through Ethernet the PC is connected to the Ethernet LAN using the stand-alone version of the 5905 Ethernet gateway. The RS-485 network is connected to the Ethernet LAN through a 5905 mounted with a SCADAPack controller. This example shows the host PC communicating with a single RS-485 network connected to the Ethernet LAN. This configuration may be expanded to include up to eight RS-485 networks connected to the Ethernet LAN via 5905 modules. Document (Version ) 5/19/

21 Operation Figure 10: Modbus/RTU RS-485 Bridging Through Ethernet Modbus/RTU RS-232 Bridging Through Ethernet Support for RS-232 serial communication using RTS/CTS handshaking allows the 5905 modules to be used as a gateway between a PC running a host Man Machine Interface (MMI) application and a network consisting of SCADAPack controllers using half-duplex, 5902 Bell 202 leased line modems. In the example shown in Figure 11: Modbus/RTU RS-232 Bridging Through Ethernet the PC is connected to the Ethernet LAN using the stand-alone version of the 5905 Ethernet gateway. The leased line network is connected to the Ethernet LAN through a 5905 Ethernet gateway module and a 5902 Bell 202 modem. This type of configuration will support many types of networks using half-duplex devices. One example would be using radio communication instead of dedicated leased lines. This example shows the host PC communicating with a single leased line network connected to the Ethernet LAN. This configuration may be expanded to include up to eight leased line networks connected to the Ethernet LAN via 5905 modules. Figure 11: Modbus/RTU RS-232 Bridging Through Ethernet Document (Version ) 5/19/

22 Network Protocols Operation The 5905 Ethernet gateway uses TCP/IP protocols for network communication. Per the Modbus/TCP specification, the Modbus data messages are transported by TCP for error-free data transport end-to-end. The IP protocol defines addressing, routing and data block handling over the network. Document (Version ) 5/19/

23 Configuration Configuration Direct Serial Port Setup Connection Configuration of the 5905 Ethernet Gateway module is made with the 5905 in the Setup mode. The 5905 may be put into the Setup mode using a direct serial port connection to the RS-232 port or a remote Telnet connection over the TCP/IP network. Once either type of connection is made with the 5905 a prompt is displayed allowing the user to enter the Setup mode. The recommended method for initially configuring the 5905 is to use the direct serial connection to enter the Setup mode. The default factory IP address of does not allow a Telnet connection. Once the IP address has been set to a unique value in the network a remote Telnet connection can be made. The 5905 configuration is stored in nonvolatile memory and is retained if power is removed from the module. The configuration can be changed any time. The 5905 will automatically reset after the configuration has been changed and stored. To enter the Setup mode using a direct serial port connection requires an ASCII terminal or a PC running a terminal emulation program such as the HyperTerminal accessory included with Windows 95/98/NT. To establish a direct serial port connection with the 5905 Ethernet Gateway and a PC running Windows HyperTerminal: In the HyperTerminal Connect To dialog box select a direct connection using an available port on the PC. In the Port Settings dialog select; Bits per second: 9600 Data bits: 8 Parity: none Stop bits: 1 Flow control: none Connect the PC serial port and the 5905 RS-232 serial port, P4, using a null modem (computer to computer) cable. Check that the 232/485 jumper, J8, on the 5905 is set for 232. To enter Setup mode: Cycle the power to the 5905 by removing and then re-applying power. When the power is re-applied the 5905 will start a self-test. Approximately one half second later the ERROR LED will start to blink. Three lowercase x characters need to be sent to the 5905, from HyperTerminal, within approximately one second after the ERROR LED starts to blink, to enable the Setup mode. Document (Version ) 5/19/

24 Telnet Network Connection The easiest way to enter Setup mode is to hold down the x key when reapplying power to the When the Setup mode is enabled the message shown in the box below is displayed in the HyperTerminal window. **Control Microsystems 5905 Ethernet Gateway Serial Number Software Version 01.1b1 (990423) Press Enter to go into Setup Mode, wait to close Configuration Press the enter key, <enter>, to enter the Setup mode, otherwise after a short delay the 5905 will automatically restart using the currently stored settings. Go to section Setup Configuration Parameters for details on changing the 5905 configuration. If the above procedure does not work perform this simple test of the cable. When power is cycled to the 5905 an asterisk character (*) will be displayed in the HyperTerminal window. If the * is not visible then either the null modem cable is incorrect or the HyperTerminal program is not configured properly. The ERROR and STATUS LEDs indicate when the 5905 module is in the configuration mode using a direct serial connection. See section Status and Error LEDs Operation for details. If the assigned IP address is known then a Telnet connection on port 9999 may be established with the 5905 Ethernet gateway. To establish a Telnet connection with the 5905: From the Window 95/98/NT Start menu select Run. In the Run dialog type telnet in the file to open box. In the Telnet window select Remote System from the Connect menu.

26 Network/IP Settings Configuration configuration menu displays the factory default configuration until changes are made and saved. The 5905 configuration settings are changed as they are edited. The settings are made permanent when the SAVE command is used. Each setting in the configuration menu is explained in the following paragraphs. The Network/IP Settings menu is used to define the IP address of the 5905 Ethernet Gateway. To enter this menu type 1 at the Select Command prompt at the bottom of the screen. IP Address The first octet of the IP address is displayed in brackets. Simply type a new IP address octet or press <enter> to accept the displayed value. Each of the four IP address octets is displayed in turn for editing. The IP address needs to be set to a unique value in the network. If the network IP address for the 5905 is not known then usually the administrator of the TCP/IP network needs to be contacted for an available address. If the 5905 Ethernet Gateway modules are the only devices on the network then the IP address block XXX, where the last number, XXX, is 0 to 254, may be used. Setting the last number to the last digit of the hardware address will make the IP address easy to remember. The 5905 module provides a convenient location at the top of the module to record the IP address. The 5905 Ethernet Gateway supports Dynamic Host Configuration Protocol (DHCP). The IP address is set to to activate DHCP. For information on using ARP to set an IP address, refer to Appendix A: Forcing a New IP Address. The 5905 will reset and generate an error message on the RS232 serial every 30 seconds if the IP address entered is already in use on the network. The error message is: ERROR: IP address conflict with xx.xx.xx.xx.xx.xx where xx.xx.xx.xx.xx.xx is the hardware Ethernet address of an existing network IP address. Set Gateway IP Address (Y/N) Set Netmask (N for default) The default value is N for this selection. When the 5905 communicates to remote TCP/IP networks through a router or gateway select Y and enter the default gateway IP address within the local network. If in doubt consult the network administrator. The default value is N for this selection. When N is selected the 5905 will automatically use the standard netmask appropriate for the IP address entered. Document (Version ) 5/19/

27 Serial & Mode Settings Attached Device (1=Slave, 2=Master) Configuration The netmask defines which part of the IP address is the network and which part is the host or Users who want a non-standard netmask need to enter the number of host bits in the IP address. The Serial & Mode Settings menu is used to define the serial port and protocol parameters for the 5905 Ethernet Gateway. To enter this menu type 2, and then enter, at the Select Command prompt at the bottom of the screen. The device attached to the 5905 may be a Modbus protocol master station to poll other Modbus/TCP devices or slave station to be polled by remote Modbus/TCP devices. The default selection for the attached device is Slave. To accept the default selection press the enter key. To change the selection to Master enter 2. Serial Protocol (1=Modbus/RTU, 2=Modbus/ASCII) The 5905 module supports both MODBUS RTU protocol and MODBUS ASCII protocol. The default selection is Modbus RTU. To accept the default selection press the enter key. To change the protocol to Modbus ASCII enter 2. The 5905 Ethernet Gateway converts both to and from Modbus/TCP completely. Any combination of Modbus RTU and Modbus ASCII devices may share a Modbus/TCP network. Interface Type (1=RS-232, 2= Four-wire RS-485, 3= Two-wire RS-485) Enter Serial Parameters (BBBB, D, P, S) The 5905 Ethernet Gateway supports an RS-232 serial interface to the attached device or an RS-485 serial interface to a single or multiple attached devices. The RS-485 interface may be selected for two-wire or four-wire operation. The default selection is for an RS-232 interface. To accept the default selection press the enter key. To select a four-wire RS-485 interface enter 2. To select two-wire RS-485 interface enter 3. Check that jumper J8 and jumper J10 on the 5905 are set for the interface selected. The serial parameters for the interface selected are entered in the format (baud rate, data bits, parity, stop bits). The default serial parameters selection is (9600, 8, n, 1). Selectable ranges for the baud rate are; 300, 600, 1200, 2400, 4800, 9600, 19200, or Selectable ranges for the number of data bits are; 7 or 8. Selectable ranges for the parity type are; none (n), odd (o) or even (e). Document (Version ) 5/19/

28 Modem Control Settings RTS/CTS Mode (1=Fixed 2=Variable) Selectable ranges for the number of stop bits are; 1 or 2. Configuration The serial parameters need to match, exactly, the serial port settings of the attached device(s). Regardless of Serial Parameters settings the 5905 configuration is done using the RS-232 serial port with the settings 9600,8,N,1. The Modem Control Settings menu is used to enable or disable hardware handshaking on the 5905 Ethernet Gateway RS-232 serial port. To enter this menu type 3, and then enter, at the Select Command prompt at the bottom of the screen. The parameters in this selection control the request to send (RTS) / clear to send (CTS) handshaking for half-duplex devices attached to the RS-232 serial port. Typically RTS/CTS handshaking is used with leased line or radio modems such as the 5902 Bell 202 modem. This selection determines whether RTS/CTS handshaking is used on the RS-232 serial port. The default selection is 1 for the RTS/CTS outputs fixed high. Selecting 1 disables RTS/CTS handshaking and closes the Modem Control Settings menu. Selecting 2 enables RTS/CTS handshaking and opens further selections for controlling the RTS/CTS handshaking. Delay After Output of RTS ( msec, 5ms resolution) Wait for CTS to Go Active (N/Y) Normally a half-duplex device attached to the 5905 RS-232 serial port will respond with a CTS signal when the 5905 module asserts the RTS signal. This is normal hardware handshaking operation. If the device attached to the RS-232 serial port cannot respond with a CTS signal, the 5905 can be set to delay from 0 to 1275 msec before continuing with data transmission. This selection has a default value of 0. A value other than zero is required only if the attached device is non-standard. To change the selection enter a value in msec and press the enter key. This selection is used in conjunction with the Wait for CTS to Go Active selection. This selection determines whether the 5905 waits for a CTS response from the attached device or continues with data transmission after the delay entered in the Delay After Output of RTS selection above. The default selection is N. This causes 5905 to ignore the CTS response from the attached device. Data transmission will occur after the delay entered in Document (Version ) 5/19/

29 Configuration section Delay After Output of RTS ( msec, 5ms resolution) section above. Selecting Y causes the 5905 to wait for the CTS response from the attached device. Check that the serial cable is properly wired to support this signal when selecting Y. Delay After CTS Going Active ( msec, 5ms resolution) This selection is only available if RTS/CTS Mode is selected as variable and the Wait for CTS to Go Active is selected as yes. When the 5905 detects that the attached device has asserted CTS, it can be set to delay from 0 to 1275 msec before transmitting data. The default selection is 0 msec. To change the selection enter a value in msec and press the enter key. Delay Dropping RTS After Transmitting ( msec, 5ms resolution) Advanced Modbus Protocol Settings When the 5905 completes data transmission, it can be set to delay from 0 to 1275 msec before dropping the RTS output. The default selection is 0 msec. The Advanced Modbus Protocol Settings menu is used to define the slave addressing and handling of Modbus broadcast messages. This menu also allows setting of the character and message timeout values for processing Modbus messages. To enter this menu type 4, and then <enter>, at the Select Command prompt at the bottom of the screen. Slave address (0 for auto, or fixed otherwise) Allow Modbus Broadcasts (1=Yes 2=No) Modbus/TCP includes a Unit Id field, which is used to address multiple Modbus slaves at a single IP address. Unfortunately, some first generation software drivers assumed a single slave at each IP address and set the Unit Id field to 0. To support these older applications, the 5905 allows a fixed Modbus address to be entered for the attached slave device. A slave address other than 0 will limit the 5905 to a single attached device. Setting the slave address value to 0 will enable the 5905 to use the Modbus/TCP Unit Id as received, allowing multiple attached slave devices. This is the default setting. This selection is available only if the slave address is set for 0 (auto). Answer Y and the 5905 module allows a Modbus/TCP Unit ID of 0 to be sent as a Modbus Broadcast. Answer N and a Unit Id of 0 is changed to a Modbus slave address of 1. The 5905 module supports a Modbus broadcast message only when a serial slave device is attached. A Modbus broadcast message from a serial master device is discarded by the 5905, regardless of this parameter setting. Document (Version ) 5/19/

30 Character Timeout ( msec, 5ms resolution) Configuration This selection sets the timeout, in milliseconds, between characters within both RTU and ASCII protocols. Modbus RTU protocol defines a 3.5 character timeout, but many modern devices have various interrupts, which can cause 5 to 10 character pauses during transmission. The default value for this selection is 50 msec for Modbus RTU protocol. This selection value fixed at 1000msec for Modbus ASCII protocol. To change the selection enter a value in msec and press the enter key. Setting this value below 50msec will not improve performance and may even make it worse uses an intelligent length-predicting algorithm to detect endof-message in Modbus/RTU. This character timeout is only used with userdefined or non-standard Modbus functions. Message Timeout ( msec, 250ms resolution) Unit ID to IP Address Lookup Table This selection sets the timeout, in milliseconds, that the 5905 will wait for a response from a connected slave. If the 5905 waits for the message timeout value without seeing a valid response from the connected slave, it will return Modbus exception response 0x0B (hex) to the Modbus/TCP requesting Master. The default selection is 1000 msec. To change the selection enter a value and press the <enter> key. This menu is visible only when a Modbus master device is attached to the 5905, as defined in menu item 2 above. To enter this menu type 5, and then enter, at the Select Command prompt at the bottom of the screen. The Unit ID to IP Address Lookup Table is used to map Modbus slave address to network IP address. When the attached master device sends a master message to a slave station the 5905 checks the Lookup table to see which IP address to send the master message. The Lookup table can map multiple slave addresses to a single network IP address. The Lookup table may contain a maximum 8 entries, representing 8 separate IP addresses. When a Modbus slave address is not found in the table the 5905 returns an exception response to the attached master. An example of a Unit ID to IP Address Lookup Table is shown in the box below. In this example there are seven entries in the Lookup table, with each entry having an individual IP address. This example shows that slave stations 1 through 10 are attached to a 5905, or other Modbus/TCP slave, at IP address D)elete, E)xit - select function Delete entry number 1): : Document (Version ) 5/19/

Selecting E, or exit, closes the Unit ID to IP Address Lookup Table and returns to the main menu. Any changes made to the table are saved. Selecting D, or delete, allows an entry to be deleted. At the Delete entry number prompt, type in the entry number to be deleted. Selecting A, or add, allows an entry to be added to the Lookup table. When this selection is made the following prompts are displayed, in order, creating a new table entry. Enter the start address of the slave stations attached to the 5905, or other Modbus/TCP slave, at the Slave IP Address. Modbus Address To Slave IP Address Enter the end address of the slave stations attached to the 5905, or other Modbus/TCP slave, at the Slave IP Address. If a single slave address is at a Slave IP Address then the Modbus Address From entry and the Modbus Address To entry will be the same. This is the network IP address of the remote 5905 Ethernet Gateway or other Modbus/TCP slave. Basic Commands (Delete / Save / Quit) The 5905 offers 3 basic commands: Document (Version ) 5/19/
