13.4 FbFC43PA
Write the volume flow (AI) address that was generated in HW Config to input parameter
AVolFlow.
Note
If you are not using the CFC function "Generate module drivers", parameterize the addresses
of input structure Addr and the Mode in/out parameter manually. The block expects the values
Mode = 16#80xxxxxx for "I/O data can be read", and 16#00xxxxxx for "invalid I/O data".
The FbFC43PA block contains a template for process tag types in the SITRANS Library as an
example.

Startup characteristics
● FbFC43PA sets bit 16#xx01xxxx of the Mode input to signal a restart.
● The module ID is read from the addressed DP Slave and verified for consistency with that
of FC430. Output QModF (module error) is set if the result is negative.
● OB100 transfers the following values to the module if the corresponding modules are
configured in HW Config:
- Reset the totalizer (SET_TOT): 16#00 (no Reset)
- Command of totalizers (MODE_TOT): 16#04 (invalid command to prevent changes of the
totalizer states)
- Dosing commands (DCtr): 16#00 (no enable, no command)
