Omron NX1P2 to C#

4 posts in this topic

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?

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.

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.

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.
