Beckhoff password

[fredo199202 0]

Hi everyone, 

I have a question about the Beckhoff PLC. I would like to put a password on the interface for managing users. For example,  to enter the advanced settings we must have a password. 

I don't know how I can better explain... 

(sorry for my english)

 

Thank you

Hi

In TwinCAT, There is several Methods for setting a password. The most strict one which no one can change anything in the Configuration is the same as Windows Login information which in any CX family can be set and anytime when you want to connect to the PLC you should have that password. There is also some levels of protection for logic interference. But most of the time the source code of the logic is not downloaded to the PLC and just the compiled version of logic is downloaded which can not be changed.
