I’m getting an error when i try to write to my PLC
Error writing to tag Almco/PLC/Packs/N9/InboundQTY
Write timed out [C].
This is odd because it seems to wirte okay, but i still get the error.
Anything in the gateway logs? What kind of device is it?

Not sure if that’s related or not.
You might send your logs into support and see if they can find anything. You can export them from the console page of the gateway.
