IGS OPC with Ignition

Hi there,

I’ll be working on a Ignition project that uses IGS OPC server to get the tags from the PLCs.

I just wanted to know if anyone has experience connecting Ignition to this OPC? I’ve seen lot of info about other OPC like Kepware but not much on this IGS OPC.

Basically, just want to know ahead if there is something to be cautious of or if I could run into any specific issues…


You should be OK. IGS is basically a rebranded Kepware distributed by GE and includes the OPC-UA server. So, you should be able to follow the instructions to add Kepware as a 3rd party OPC-UA server to Ignition.

I just did a proof-of-concept with the Ignition 8.0.3 nightly and IGS 7.66 and it worked without issue. By default, IGS doesn’t seem to have OPC-UA SecurityMode None enabled so you either have to enable that on the endpoint (and reinitialize IGS) or make sure you’re trusting the Ignition certificate in IGS.


Thank you!
