Hello. I need to connect an EtherNet/IP adapter to CODESYS RTE.
I have confirmed that the adapter works with Rockwell Logix, and not only the communication but the process data works as expected. The device echoes back the output from the PLC.
I have tested with both CODESYS Winx64 and CodesysRTE (both licensed with USB dongle).
The problem I get is that PLC application for the selected adapter shows status "The bus is not running. The shown values are perhaps not actual." Wireshark traces shows normal implicit communication and the output from the PLC is seen on the network.
The adapter has 4 bytes assemblies and 254 bytes assemblies. The problem seems to be with the 254 input (or produced) assemblies. It is not possible to get the data from the input assemblies to the PLC application.
Is there are known limitation for IO connection for the CODESYS EtherNet/IP scanner?
