Testing Connection on form
« on: December 17, 2013, 07:36:29 PM »
So I'm using 1 driver to communicate with several IPs by just changing IP in the code and its working just fine but theres one problem. When I change the IP to a plc thats not even connected and try to send info to it there are no errors thrown. This could be a problem if an operator ever sends info to a PLC thats not connected. I'm using a CLXIP driver, is there a way that when I change IP address it will test if its successfully communicating?

On the CLX driver there is a ConnectionEstablished event that you can handle to know when it has connection to the PLC.

In the form load, I put PLC.ReadClock().  This force ConnectionEstablished event to fire and inside this event , I set PLCIsConnected = True and use this boolean throughout the program. The PLC.ReadClock need to be in the try catch statement.
