SECS/GEM module that Ignition is provided is having a simulator for testing purpose.In the documentation of SECS/GEM simulator in Ignition,simulator will respond to some default messages only.I want to know messages or stream functions other than default messages will respond by SECS/GEM simulator,I tried with echo response feature but it is giving “None” for messages which are not default eg
