Dear Sir/Madam,
We have installed quantity of 13 main PLC of modicon series 984-785E for different departments of plant. Each Plc has Remote I/O processor S908-110 and many remote I/O Interfaces of type J890-101.

In one of the department we have a drop having rack installed with P810 supply and Remote I/O interface module j890-101 which is connected to network of S908. only the Ready LED on card is ON , we are not getting any error LED. also the commuincation active LED is OFF.

Now we want to use that rack in provided as spare to install add new I/O modules in the rack. we have adjusted the network address of J890 to 4. now the problem is that commoniction active signal is LED is not on?
why this so? how can we solve the problem?
