Hello everyone,

I’ve setup an Siemens IM151-8 with OPC-DA(com) talking with Ignition…  
At the “status” page everything seems to be ok - Device connected, OPC Server Connected.

At the “Designer Page” and “Quick Client” I can also browse and see the variables configured at Step7. But when request “READ” comes back status “Stale” (see picture attached)

I have the Simatic Net Scout running, and I see all the values changing life, and connected.

Any help or idea why is not connecting on Ignition side is truly appreciate !!
