CP1L PLC network communication error

[Yash_Trivedi 0]

Hello all,

 

I have a master PLC(CJ2M) which is communicating with slave 4 slave PLCs(CP1L). one of the PLC have communication error, upon checking in cx-intergrator it shows that all the other slave PLCs and other components are connected to network-1 and faulty PLC is connected to network-0. Unfortunately, I couldn't change it as cx-intergrator doesn't allow me to change download the changes. So anyone can please help me with this issue. If you know the troubleshooting way then please reply. 

 

Thanks in advance.

What is the full part number of the PLC?

Does the PLC have an Ethernet module? If so, what is the part number?

Did you place the PLC in to Program Mode first?
