I am preparing my first proof of concept for a project using Ignition. We have a project built in the designer and we are currently working on connecting a PLC to the project. We have established a successful PLC connection to Siemens S7 1200 on the gateway but we are having problems reading/writing to tags that we have created in the designer. Please find attached screenshots of the errors we are getting. Any help would be much appreciated.
Thanks for the response but we have already followed those instructions to no avail. Is there anything else we can do.
Double check you’ve made all 3 of those changes if they weren’t already configured properly and then do a recompile and download of the PLC program. I think I’ve heard of some cases from support where the recompile was necessary for it to take effect for some reason.
You were on the money there.
For reference, i did a full hardware download (rebuild) of the PLC on Siemens TIA, restarted the designer and it worked.
Thanks for your help
You da man
