Note
If you group the modules with the IM151-1 HIGH FEATURE
in DPV1 operation in STEP7 applications, the following occurs:
S
No removal/insertion interrupts are triggered for these modules in STEP 7. In
this case, you can detect that a module has been removed if you evaluate the
module status in the diagnostic frame.
S
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.
