Hi, there,

I am new to this, so please don't mind my ignorance.

I am running industrialcoom/S7comm with PLC S7-200. Everything seems to work well. Sometimes I get comm.error but that's very rare, When I start RPI I get following S7 error messages in my log, I don't understand why, can anybody tell me?

I recently noticed I have the same problem. I migrated the node-red server from Windows to Linux and now I get this same error.

I'm using it with S7-1200 and S7-300 PLCs.
