Posted 31 Oct 2019 Hello PLC gurus, I have a really noob question to ask. I am new to ethernetIp programming. I have a 1756-L61 that is supposed to communicate with another device over EIP. The Ethernet object assembly is set like this Input assembly instance: 100. Size 1 Output assembly instance: 254, configuration instance:1, Size 0 Read data: 2 word Write data: 2 word Does anyone know how I can set up the producer/ consumer tags to read and write to the data block over eip?? I thank all of you in advance Share this post Link to post Share on other sites
Posted 31 Oct 2019 I don't think you can use produce-consume tags except between ControlLogix/CompactLogix processors, but I could be wrong. If your other device isn't a Logix 5000 processor, I think you need to use a generic Ethernet module or get an AOP for it. What is the other device? Share this post Link to post Share on other sites
Posted 31 Oct 2019 Thank you Joe for your reply. I believe it's an Omron PLC. There's an EN2T module on the CLX side. What's an AOP? Share this post Link to post Share on other sites
Posted 31 Oct 2019 AOP = Add-On profile. It lets you add a device to the Logix 5000 I/O tree, which makes it far simpler to communicate with. Does the Omron PLC support Rockwell's Ethernet/IP? If not, you'll need a protocol converter that can talk to both. I can vouch for the Red Lion DSP communicating between Siemens and Rockwell very well but I've never used Omron hardware. The DSP lists "G9SP-Series via FINS" and "Master via FINS" drivers for Omron. I don't know anything about them, though. Share this post Link to post Share on other sites
Posted 31 Oct 2019 Yes, Omron uses Ethernet/IP as defined by ODVA. So, now communicating with the Omron is as simple as adding an ethernet module? Will this configuration work if the Ethernet module is connected to a switch? Thanks Share this post Link to post Share on other sites
Posted 31 Oct 2019 A switch shouldn't matter, just make sure the two devices are subnetted and addressed properly. In the I/O tree, expand the EN2T to reveal its Ethernet network, right-click on the network and select "new module". In the dialog box, find generic Ethernet module: In the next dialog box, set its name, IP address, etc. Here's an example from one of our machines that's talking to an data collection PC: Your setup will be different. I can't help you with the Omron side, or test the setup since we don't have any Omron devices here. 1 person likes this Share this post Link to post Share on other sites

Posted 2 Nov 2019 I've always wonder why people run straight for produce/consume. You guys need a snickers. Share this post Link to post Share on other sites
Posted 5 Nov 2019 @IO_RackThank you for the instructions Share this post Link to post Share on other sites
Posted 5 Nov 2019 @NevergoldMel I guess it's due to not having a deep understanding of produce/consume tags. There are a lot of PLCs on the market and it's hard to keep up with all of them. Can i have my snickers now? Share this post Link to post Share on other sites
