Hi Everyone,
Usually, We are giving a PLC Program with password to customer for backup & diagnostic purpose. These days we are notice that the customer doing changes in PLC program without inform to us. If any malfunction is happend due to the changes, then they will download original copy & call us . So, I want to stop this activity.
Therefore, How we can identified that the PLC Program is re-downloaded (same copy of Program ) ?.
Note: 1. PLC can be any make.
2. Retentive memory can not used.
Regards
Nilesh
