Programming Reference 1
Security menu (only KSU-II/KCM) 1.12
1.12.2 Function data lock out
To activate the security function is it necessary to assign a digital input
to <Data Lock> by KCM/KD or use the data lock input from KSU-II and
to connect a key switch to that input. To enable the security menu to
change the settings the key switch needs to be closed. When the
settings are made and the key switch is opened, the security menu
and all the menus set to read only, will be read only. To prevent that
an operator can disable the key switch in the I/O menu, the I/O menu
should be set to read only or to hidden. For additional information see
manuals for KCM Electronics manual and for KSU-II 0490020604.
