Hello, I have a problem with Modbus TCP communication. When I try to add an Ethernet device to the project and compile, then a list of errors pop up, regarding IoDrvEthernet library. I'd like to ask for some help how to solve this problem. I'm not working in Codesys from a long time. I was trying to 'Update device' but only one version (3.5.15.0) is available. I was trying to add manually the IoDrvEthernet library, but it didn't help. I'm using PLC Festo CECC-D, my CODESYS version is V3.5 SP151 Patch...
