5.8.2 CPU parameters
The CPU does not evaluate each parameter, which may be set at the hardware configu-
ration. The following parameters are supported by the CPU at this time:
n
Short description:
The short description of the Siemens CPU 313-5BF03 is CPU 313C.
n
Order No. / Firmware:
Order number and firmware are identical to the details in the "hardware catalog"
window.
n
Name:
The Name field provides the short description of the CPU. If you change the name the
new name appears in the Siemens SIMATIC Manager.
n
Interface:
Here is the address of the MPI interface.
n
Properties:
By means of this button you can change the properties of the MPI interface.
n
Comment:
In this field information about the module may be entered.
n
Startup when expected/actual configuration differs:
If the checkbox for
‘Startup when expected/actual configuration differ’
is deselected
and at least one module is not located at its configured slot or if another type of
module is inserted there instead, then the CPU does not switch to RUN mode and
remains in STOP mode. If the checkbox for
‘Startup when expected/actual
configuration differ’
is selected, then the CPU starts even if there are modules not
located in their configured slots of if another type of module is inserted there instead,
such as during an initial system start-up.
n
Monitoring time for ready message by modules [100ms]:
This operation specifies the maximum time for the ready message of every configured
module after PowerON. 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.
n
Transfer of parameters to modules [100ms]:
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.
n
Update OB1 process image cyclically:
This parameter is not relevant.
n
Scan cycle monitoring time:
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
