i, I have lost communication with the USC-B-TR22 I am using and seem unable to re-establish it. I had the IP addr set to 192.168.0.64 for the panel and 192.168.0.65 for the CPU, and this was working. I then compiled my first program and downloaded it to the unit, when I tried to VPN it to try it out an error appeared, 'incorrect IP address'. I checked all the IP addresses and noticed they had both changed so I put them back to the above address but could not get comms. I set them to the default values but no difference.
The program was just a simple one, as I am trying to teach myself, on the HMI I put a button and an indicator, when the button is pushed DO0 changes state and the indicator monitors DI0 for that change in state.
I am not too worried about the program as yet just the communication issue, any help much appreciated.
