I am using the B40 module configured for Ethernet/IP. I am running the device against the ODVA CIP Protocol Conformance Test Suite CT18. According to ODVA’s website, Ethernet/IP certification requires testing of the LLDP Management Object (265). When running the tests, I get failures during the Error test.
The failures occur when writing (set attribute single) to LLDP Management Object instance 1 attribute 2 (msgTxInterval). The tests attempt to write 1, 2, 3, and 4 to that attribute. The write succeeds, but the test expects a failure response and returns an “Unexpected success response” message.
These failures are confusing to me because the tested values seem to be in line with the allowed values described Network Guide - Ethernet/IP. According to that document, msgTxInterval accepts values from 1-3600, so I would not expect 1-4 to fail.
I have attempted editing the Value Limits of the attribute and Parameters of the Set Attribute Single service within the STC Editor the test suite provides, but I have not been able to get rid of these errors.
