Deleting Cir Elements - Siemens SIMATIC CPU 410 System Manual

Plant changes in RUN - CiR
11.8 Procedure for PROFIBUS DP
3. Using drag-and-drop, move the CiR module from the hardware catalog onto the slot
directly after the last configured module of the DP slave in the lower part of the station
window. (If you automatically add CiR elements, this rule is automatically taken into
account.) The CiR module then appears in the lower part of the station window as a
placeholder module.
The number of input bytes and output bytes are displayed in the properties window of the
CiR module.
4. For ET 200M stations, this is determined as follows:
– Number of input bytes = Number of free slots * 16
– Number of output bytes = Number of free slots * 16
Note
For ET 200iSP, a maximum of 244 input bytes and output bytes are available. You can
find the input and output bytes of the individual electronic modules in the ET 200iSP
manual.
Downloading the configuration
After defining the CiR elements you download them with the CPU in STOP operating state.
A large number of modules can be used in the S7-400 automation system. To ensure that
none of the modules you are using will prevent a future CiR action, you must adhere to the
following procedure: Once you have downloaded the configuration in STOP operating state
of the CPU, immediately download it again to the CPU, but this time with the CPU in RUN
operating state. When this is done, STEP 7 and the CPU will check the CiR capability. With
older modules or modules from third-party manufacturers, this is not yet possible offline.

Deleting CiR Elements

Deleting all CiR Elements
Note
You can only delete all CiR elements if a CiR object exists in the selected DP master
system.
Downstream of an IM157 it is not possible to delete all CiR elements on a DP master
system.
176
In an ET 200M station that contains only a CiR module, this value is thus 128 (if the
CiR object on the DP master system still has a sufficient number of free input and
output bytes).
In an ET 200M station that contains only a CiR module, this value is thus 128 (if the
