Assistance Needed for Tag Value Transfer Between Schneider M340 and AB Micrologix PLC in Ignition 7.6.6

I am currently working on an older Ignition SCADA system, version 7.6.6. The system has two devices connected: a Schneider M340 PLC and an Allen-Bradley Micrologix PLC.

I need to read the value of a tag from the Schneider PLC and write it to a tag in the Micrologix PLC whenever the Schneider tag value changes. Is there a way to accomplish this in Ignition version 7.6.6?

Apologies if this is a basic question—I'm still learning this SCADA system. Any guidance would be greatly appreciated!

The easiest thing to do would be a gateway tag change event script that watched the Schneider tag for changes and then wrote it to the MLX tag.

Sorry, I don't have any documentation or user manual I can link to for such an old version.

In the current version it would be this: Gateway Event Scripts | Ignition User Manual
