In summary, wiring for power, communications and I/O is connected to the gateway. Then, setup choices are entered using the Sixnet I/O Tool Kit software and the system will be ready to run. Shown below are some typical system configurations. The ET-GT-ST-3 allows you to build Ethernet I/O stations of as little as 8 I/O channels to as much as 620+ I/O channels. Each ET-GT-ST-3 has two independent Ethernet network ports. This allows you to have redundant Ethernet links to ensure that a simple cable failure will not cause you to lose your I/O. The ET-GT-ST-3 can also be used in conjunction with the SixTRAK IPm Open DCS Controller to provide both redundant network connections, redundant controllers and redundant I/O. With this scheme any single failure of controller, gateway or cable is tolerated.

Sixnet I/O Tool Kit The ET-GT-ST-3 is configured using the Sixnet I/O Tool Kit software. Configuration parameters are written over Ethernet or RS232 into permanent memory in the unit. Refer to the Sixnet I/O Tool Kit help for details. The basic steps are: 1. Connect SixTRAK I/O modules and DC power to the unit as prescribed in a previous section of this manual. 2. Connect the unit to your Ethernet network via an Ethernet switch or directly to your PC. Make sure the LNK LED on the unit comes on solid (not blinking). 3. Run the Sixnet I/O Tool Kit, add an ET-GT-ST-3 station and define the parameters for the unit. Be sure to: Choose an IP address that is appropriate for your network. See the help file for details. Enter in the serial number that is printed on a label on the unit. Choose a station (slave) number for the unit that is unique. 4. Once you’ve completed the wizard, save your project file. Go to the Device menu and choose Serial Port for the communication device. Then go to the Operations menu and select Load. This should set the IP address in the module and then load down your other parameters. 5. Go to the Device menu and choose Ethernet for the communication device. Then go to the Operations menu and select Verify. If this Verify fails for some reason, here are some items to check: 5. Make sure the LNK LED is on solid. If it is off or blinking then a typical cause is a bad cable, an incorrect cable, or you are plugged into the wrong port on your hub/switch. Try to “ping” the unit. Ping is a utility that comes with your PC. Start an MSDOS prompt and type “ping” followed by the IP address of the unit and then hit <CR>. For example, “ping 10.1.0.1” (do not type the quotes). If you get an “unknown command” error then you will need to install the TCP/IP Ethernet protocol on your computer. If you get “destination unreachable” then make sure the gateway’s IP address is valid with respect to the IP address and subnet mask of your computer. If you get “request timeout” then check all the items above. For more info., refer to the Sixnet I/O Tool Kit help system. Once you establish that you can communicate with the unit from the Sixnet I/O Tool Kit you then should attempt to communicate with your device using your master software.

It responds to read and write messages from a master PC, controller, RTU, or other device. EtherTRAK stations can respond to messages on all their ports at the same time, allowing for multiple master interrogations. Each serial port can be set for a different protocol (Sixnet or Modbus). Each port can also be configured for slave, master, or Sixnet passthru mode. The two Ethernet ports will respond to Sixnet or Modbus protocol automatically. No protocol configuration is necessary. Master Mode – The ET-GT-ST-3 can act as a Sixnet or Modbus protocol master over its Ethernet or Serial ports. Just configure the port as a Modbus or Sixnet Master and then define I/O Transfers to your slave stations. Refer to the I/O Tool Kit on-line help for details on configuring I/O Transfers. Master to Master Mode – This advanced mode allows two master devices to use the ET-GT-ST-3 to exchange I/O data. In this mode one port is configured for Slave operation and must be connected to a Modbus or Sixnet master device. This device then can write/read I/O data to/from the internal registers of the gateway. Another master device can then do the same on one of the other ports. With this scheme the two ports can be using different protocols. The ET-GT-ST-3 has thousands of I/O registers available for relaying data. Passthru Mode – The ET-GT-ST-3 can be configured for Sixnet Passthru operation. When so, it must be connected to a Sixnet slave device. The Ethernet port must be connected to a master device (via a switch or hub) such as a PC, PLC, or Sixnet controller/RTU. When the gateway receives a message on the Ethernet port from the master device it will look at the station number in the Sixnet message (embedded in a TCP or UDP packet). If the number matches its own then it will respond directly to the message. If the number is anything else then it will pass the message out the other port.

Diagnostic software, such as the Sixnet I/O Tool Kit, can be used to display the status of the I/O registers. Refer to the software’s on-line help for details. Status LED The “Status” LED on the unit indicates its operational status: ON The unit is operating properly. OFF There is no power to the controller or service is required. Contact Sixnet technical support. FAST BLINK This may occur when the unit is being reset, or firmware is to be downloaded from the I/O Tool Kit software. SLOW or PERODIC BLINK Memory This indicates that the internal watchdog has detected a problem. Try clearing the memory and reloading the project from the I/O Tool Kit. The ET-GT-ST-3 has nonvolatile (battery-free) memory for storing configuration data from the I/O Tool Kit utility. It also has battery-backed memory for storage of I/O registers. The battery is a rechargeable lithium cell that is kept fresh by the power circuitry in the unit. The memory retention period for an unpowered unit is at least 6-months at room temperature. The retention time will be shorter at higher temperatures. The life expectancy of the lithium battery is approximately 10 years or more.

We suggest that you give us a repair purchase order number in case the repair is not covered under our warranty. You will not be billed if the repair is covered under warranty. Please supply us with as many details about the problem as you can. The information you supply will be written on the RMA form and supplied to the repair department before your unit arrives. This helps us to provide you with the best service, in the fastest manner. Normally, repairs are completed in two days. Sometimes difficult problems take a little longer to solve. If you need a quicker turnaround, ship the unit to us by air freight. We give priority service to equipment that arrives by overnight delivery. Many repairs received by mid-morning (typical overnight delivery) can be finished the same day and returned immediately. We apologize for any inconvenience that the need for repair may cause you. We hope that our rapid service meets your needs. If you have any suggestions to help us improve our service, please give us a call. We appreciate your ideas and will respond to them.
