CP1W-CIF41 Ethernet Module Cannot Connect

[skjomcs]

Hi I have a CP1W-CIF41 ethernet board in an Omron PLC. I connected to the board to change its IP address via its default IP and lost connection before the operation got completed. I now cannot connect to the board via the default IP address or the new IP. Have tried changing cables, switches etc but cannot connect . Is there a way to reset these so i will know it is back to its default IP address of 192.168.250.1

Hi, First of all you can not change the ip address of cif41 via web browser directly. You can see an article about changing ip address of cif41 below link. http://www.myomron.com/index.php?action=kb&article=1212 And about your problem, you can see the ip address of cif41 via plc. Did you try it? To check the ip address look "n+155 and n+156" n = DM32000 + 300×(0xFD - Unit Address) Unit address for Option port 1(if I/O capacity 14/20 ) 0xFC, (if I/O capacity 30/40/60) 0xFD Unit address for Option port 2 (I/O capacity 30/40/60 ) 0xFC -- ozeufu

If the unit is V2.0 It is possible to reset it to default. by using A525.00 A525.01

I dont want to change the ip address

i want to use default ip address

i connected before and now CIF41 not connected

When i connect CIF41 to hub no led of hub on and bot detect the CIF41

maybe CIF41 out of service?

i must change the module?
