Q: How to find out password of PLC
A: If you forget the password, you can’t connect to PLC. In this case, removing all PLC program or clearing memory is the only way to connect to PLC.
(Once PLC program is removed, it can’t be restored.)


When CICON connects to PLC (Online), you need to insert password if you already set up password before.


If you forget the password, CICON can’t access PLC CPU module.


In this case, remove all program and data of PLC CPU module to use it.
