 |
|
Hi all!
There is a Loehrke CDES 40 chlorine dioxide unit. PLC and HMI from Siemens.
Several outputs on the controller have failed and as a result the installation is currently not operational.
We wanted to unload the project from the controller and load it into a similar one - it was not possible, the project in the controller turned out to be password protected.
Perhaps someone knows what the controller password might be? Or is there a standard password for a given hardware manufacturer?
I would be very grateful for any information! |

The above methods will cause me to lose the program, and I don't have the autentic program.
I just need to gain access to the program. |
