naing Posted July 14, 2006 Report Posted July 14, 2006 Hello, I am now servicing a plant controlled by S7-200 (CPU226). By needness, I have to access the PLC online. I can upload/download the main program with STEP7 MicroWin. But I can't enter into the subroutines protected by password. Please give me the solution without need to contact the original machine builder. Thanks a lot. Quote
Crossbow Posted July 16, 2006 Report Posted July 16, 2006 The passwords for their subroutines allow them to protect their code. You need to contact the machine builder for access to that code. Quote
