Hello all,
I have a client who bought some machines from a vendor that passworded the PLCs. One of the S7-1200 PLCs went into stop mode. I knew that the PLC was passworded and I had no interest in recovering the code. I only wanted to switch it in RUN mode using the online access.
I think this is a huge flaw in the S7-1200 design as there is no point in that. Why not be able to set the PLC mode?
In the S7-1500 or ET200sp one can use the mode switch to put the PLC back in RUN, regardless if it is passworded or not.
Also I believe that the programmer did a poor job preventing the PLC to go in STOP mode or not warm restarting it Always in RUN mode.
