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?
