Hi,
we are using Siemens S700 PLCs with add-on modules
and use the TP170B screen (and the replacement TP177B).
A service engineer with thick fingers have managed to
enter an unknown password for the control panel on a
couple of screens. We have not been able to figure out
what was entered.
Does anyone know how to unlock the password
so it can be re-entered correctly?
