Caution when replacing a CPX terminal
with saved parametrisation
(LED M lights up):
In case of servicing, such as with
replacement of the CPX terminal,
parametrisation is not created
automatically by the PLC or the
higher−order system. In this case,
check which settings are required
before replacement and make these
settings if necessary.
The Force function has been activated
(Force mode; Function No. 4402, see
CPX System Manual P.BE−CPX−SYS...).
