Note
The data in the feedback data record is always mapped for all modules. In a Shared Device
configuration, it is therefore irrelevant which IO controller the respective modules are
assigned to.
As long as no control data record was sent, a one
-to-one module assignment is assumed for
the compilation of data record 197 (station master → station option).
Error messages
In the case of an error when reading the feedback data record, the RDREC instruction returns
the following error messages via the STATUS block parameter:
Table 11- 8 Error messages
Error code
Meaning
80B1H
Invalid length; the length information in data record 197 is not correct.
80B5

Configuration control not configured
80B8
H
Parameter error
The following events cause a parameter error:
• Incorrect block ID in the header (not equal to 197)
• Invalid version identifier in the header
• A reserved bit was set
• Multiple slots in the station master are assigned to the same slot in the station
option
11.2.2.4 Examples of configuration control
A station master consisting of a system power supply, CPU, and three I/O modules is
configured in STEP 7 in the following section.
The module at slot 3 is not present in the station option 1 and is "hidden" by the
configuration control.
In station option 2, the order of the modules in slots 3 and 4 is interchanged. The modified
order of the modules is made known to the CPU by a modified control data record.
