I am trying to connect RaspberryPi(installed CODESYS 3) to PLC using EtherNet / IP.
In this system, PLC is a scanner and RaspberryPI is an adapter.
I was able to connect PLC and RaspberryPi by Forward_Open command.
However, I could not get RaspberryPi's data using ExplicitMessage, and I got an error response.
(General Status code : 0x14 => "Attribute not supported")
When I checked the command output from the PLC, "Logical Format" was "16-bit logical value".
I want to connect PLC to RaspberryPi with "16-bit logical value". Do I need to make any configuration changes?
When I conducted a communication test using two RaspberryPi (one scanner + one adapter), data was successfully acquired."Logical Format" was "8-bit logical value" when communication was successful.
Could you help me this problem ?
