I received a PM from Forum member @zhoudq and am creating this public thread for his question:
I wonder to use a MSG instruction pull the 1756-CN2R data, but i can't set the MSG parameters, because i don't understand the MSG parameter meaining, example:service code, class ,instance, attribute etc.
In addition, I get the data form the module EDS, the Listen Only - Rack Optimized path is 20 A7 24 01 2C 03 2C 01, but i don't understand the meaning, please guide me or give me the user manual of the parameter. thank you!
