Hi,

I’m trying to implement E142 Substrate Mapping using the SECSGEM module. I have been at trying to get the sdl files and an echo response properly formatted to get a response within the script terminal for days now and I cannot seem to get each file formatted correctly. I have received multiple errors for the message not matching the definition. I also tried duplicating what seemed to work for someone else from this old post  
[SECSGEM post](http://forum.inductiveautomation.com/t/secs-definition-language-sdl-file/15786/15)

Has anyone been able to successfully implement E142 using ignition?
