I am looking for the best way to share tags between Ignition and iFix. Ideally, I would want everything to be moved to Ignition, since iFix is a hassle, but for now I am only using pieces of Ignition that are clear upgrades over the iFix equivalent. However, since I’m using both I am running into issues getting them to talk to each other. Both are connected to a ControlLogix PLC, so I can pass tag information that way, but it is slow going from iFix->PLC->Ignition and back again.
iFix has an OPC-UA server that is connected to the PLC and an OPC-DA server. Going through OPC-UA hasn’t gotten anywhere besides being able to see iFix’s OPC-UA connection to the PLC. I’ve messed around with the OPC-COM module trying to connect to iFix, and running into all the issues that occur with OPC-DA. I should be able to connect to the iFix tag database that way – but any standalone tags I create there (SIM tags) are non-retentive which is something I would like to avoid.
I suppose what I am really looking for is a way for iFix to read/write to tags stored in Ignition (since Ignition tags are retentive). I saw this topic: https://www.inductiveautomation.com/forum/viewtopic.php?f=71&t=5716&start=0&st=0&sk=t&sd=a which appears to be related to my issue, and indicates there may have been a solution in the works, but I haven’t seen anything further.
