Have have an ETN module for my CJ PLC that is talking to some displays (numeric) via socket services over ethernet. There are three displays with different addresses and one of them keeps locking out. The socket services error I get back is 0053 "Error in communications with remote node (ETIMEOUT) or remote node does not exist".

Now I might have a display problem here, i'm going to swap them round and see if the fault moves. I'm on with that.

Is there anyway of resetting the ETN unit in PLC ladder? I could trap the error if it occurs and simply reset the unit. Or is there any less basic way of resetting the socket other than closing and reopening?

Many thanks,

Dave

Dave,
I think you can reset the ETN unit by turning on the CPU Bus Unit Reset Bit. The location is A501.00 - A501.15. Check the unit number on the ETN card, this is the bit number 0-15. I'm curious why the display keeps dropping out?
Hope this helps!

Thanks EasyButton, i'll give this a whirl,

Cheers
Dave
