hello guys

there's anyone know how to clear the error

my plc CJ1M CPU11 have an ERH led blinking

how can i do in order to reset the error?

You must be talking about CJ1M-CPU11-ETN because the ERH light is for the Ethernet.

ERH Flashing:

An illegal IP address has been set. With automatic address generation,

the rightmost two digits of the IP address do not match the

node address.

Set the rotary switches to match the last octet of your IP address.

hello Jay ...

yes exactly you are correct...

so i have to set the rotary switch in order to match with the last octet of PLC address? yes or no?

also i have another problem

if the ERh led is blinking, then it would distract my PLC networking using Ethernet through Wide Area Network or not?

because am still can connect my PLC

Thanks Jay

Since your subnet is 255.255.252.0 (from other post), you will also have to worry about this issue:
