Posted 30 Sep 2022 Hi, I'm developing an application in C# and need to communicate with a plc omron NX1P2. How can i do it? With cx-compolet? Or is there another way? Share this post Link to post Share on other sites
Posted 30 Sep 2022 The NJ and NX processors support symbolic access via Ethernet/IP using the same read & write services as Rockwell uses. See Rockwell's Logix 5000 Data Access manual. 1 person likes this Share this post Link to post Share on other sites
Posted 1 Oct 2022 I've used socket services for this in the past. Essentially send TCP commands like you would over Telnet and parse them out in the PLC. 1 person likes this Share this post Link to post Share on other sites

Or is there another way? pturmel said nice stuff. You can use E/IP library for .NET and your communication will be more advanced, compare to old fashion TCP/UDP styles. I'm not saying that it's wrong or so. TCP and UDP still valid and very useful communication protocols. But E/IP will be a bit comfortable and convinience. PLC won't require to do extra steps to build a message for transaction and your application won't need to parse the data. Share this post Link to post Share on other sites
Posted 9 Dec 2022 It's very easy to create a socket and exchange data by UDP or TCP. You can exchange data in structure without conversion. Share this post Link to post Share on other sites
