| Solution: |
| The problem here is in the Toshiba V PLC. You have to to tell the processor where the NO1 card was located (slot number) and the port number CitectHMI/SCADA was going to talk to it via. The settings that you need to change reside in the configuration of the processor. For further information refer to Knowledge Base articles Q3046 and Q1667. |
