This operation specifies the maximum time for the ready message of every
configured module after PowerON. Here connected PROFIBUS DP slaves
are also considered until they are parameterized. If the modules do not
send a ready message to the CPU by the time the monitoring time has
expired, the actual configuration becomes unequal to the preset
configuration.
The maximum time for the transfer of parameters to parameterizable
modules. If not every module has been assigned parameters by the time
this monitoring time has expired; the actual configuration becomes unequal
to the preset configuration.
This parameter is not relevant.
Here the scan cycle monitoring time in milliseconds may be set. If the scan
cycle time exceeds the scan cycle monitoring time, the CPU enters the
STOP mode. Possible reasons for exceeding the time are:
•
Communication processes
•
a series of interrupt events
•
an error in the CPU program
This parameter is not relevant.
The preset reaction of the CPU may be changed to an I/O access error that
occurs during the update of the process image by the system.
The VIPA CPU is preset such that OB 85 is not called if an I/O access error
occurs and no entry is made in the diagnostic buffer either.
Activate the check box if you want to use clock memory and enter the
number of the memory byte.
Note!
The selected memory byte cannot be used for temporary data storage.
