The LED M is intended for several functions (see also under
Interbus-specific LEDs). The status which is shown takes
place in the following sequence:
1. Force active
2. Parameters saved remanently
Meaning/error handling
None
Be careful when replacing
CPX valve terminals with saved
parameterisation.
With these CPX valve terminals,
parameterisation is not carried out
automatically by the higher-order
PLC/IPC when the terminal is
replaced. In these cases check before
replacing to see which settings are
required and, if necessary, carry out
these settings.
The force function is enabled
(see system parameter force mode;
function no. 4402).
