Also we will need to access this block automatically when we load OB1 in the program. I need to do this, for a software interlock of the hardware buttons that are connected to a PLC DI/D0 card. Thanks !

Thanks ! Hello Alexander: let me see if i understand your question: You will like to avoid to execute some tasks in your PLC if a user do not write a pasword right? Ok let me ask you first, how are you plannig to "access" the pasword? By means of S7 or simatic manager or by means of HMI, or other way? Please tell us more about and we will give you a beter answer. Have a very nice day .
