4.9.3 Reaction of the Output Modules in STOP or HALT State
With transition from RUN state to STOP or HALT state of the CPU41x the
values at the TELEPERM M output modules normally remain unchanged.
This reaction can be changed by configuration.
For that the following pseudo module has to be defined within DB1 of the
FM456-4:
Module type: STOP:NULL_TO_OUT
Cycle: n = 0 or 0 < n < 21, with:
n = 0 (default value): The last output values survive if the
CPU goes to STOP or HALT.
0 < n < 21: If the CPU goes to STOP or HALT,
the outputs are set to zero if a corres
ponding setting has been done on the
module. On this (n-1) * 250 msec
will be waited between occurrence
of the STOP/HALT state and the
zero output.
If the CPU changes from the STOP/
HALT state to the RUN state during
this waiting period, the last output
state survives.
4.9.4 Diagnosis Function: Time Measurement at FM456-4
This function gives information about the FM456-4 load, and about the com-
munication running times between CPU41x and FM456-4.
But the interpretation of this data can only be done by the TELEPERM M
support.
With the following configuration of a pseudo module within the DB1 data
block of the FM456-4 this diagnosis function can be switched on/off:
Module type: DIAG_FM456***
Cycle: n = 0 or n > 0, with:
n = 0 (default value): Diagnosis / time measurement
deactivated on the FM456-4.
n > 0: Diagnosis / time measurement activated
on the FM456-4.
