Hello there !
Does anybody know how to poll data from Igntion to ETAP (Electrical Transient Analyzer Program) and visceversa?
Regards 
Hi David,
Does the data used in ETAP support OPC-UA, or any of our device protocols listed here? OPC UA Drivers - Ignition User Manual 8.1 - Ignition Documentation
If so, it may be possible to connect to this system through our device drivers. Feel free to share any other info here on how ETAP systems are typically connected to and the forum may be able to assist with recommendations for next steps for connecting to it from Ignition.
