Note
In STEP 7 applications, if you group the modules in the IM151-1 HIGH FEATURE
in DPV1 mode, the following occurs:
No removal/insertion interrupts (OB 83) are triggered for these modules. In this
•
case, you can recognize a module that has been removed from the module
status in the diagnostic frame in the cyclic user program.
Each grouped module then receives its own diagnostic address.
•
– There can be a total of no more than 8 channels (1 byte).
3. Select from the hardware catalog of your configuration software the module
designation without "*". Result: You open a byte and store the first module
there.
4. Select from the hardware catalog of your configuration software the module
designation with "*". Result: In the open byte, you store additional modules until
all the bits are occupied.
5. If a byte is filled, you must configure a module again (that is, open a new byte
without "*").
Note
Configuration by means of the GSD (device database) file: The configuration
software does not check whether the modules have been grouped correctly. If you
configure more than 8 channels in one byte, the modules that exceed the byte limit
are reported as being incorrectly configured in the diagnosis:
Module status ––> 10
These modules are not addressed.
