All,
I know this type of question has been asked (and sometimes answered) ad infinitum but after looking I'm still stuck and could use some help.
We have several Micro 850's here and need to log a few tags via Ignition Scada. I've mapped the Modbus addresses and can access what I need on most Micro 850-'s but one is being difficult. It's also talking Modbus serial to an AB HMI.
Using Ignition (or alternatively a simple client like 'Simply Modbus') yields a 'tag does not exist' Modbus error. The issue has been reviewed by RS Tech support (the assistance was not exactly enthusiastic) and Inductive...no one has been able to figure this out.
Any pointers or help from the community would be greatly, greatly appreciated!
Thanks,
John
