Parameterization
The program supplies and removes the FB largely by directly accessing its
instance DB, so that many formal parameters can remain unconnected.
Only the following entries are assigned with actual parameters:
“control_word” of type “WORD”,
Control word, supplied by the Simulation block [FC10].
“setpoint” of type “REAL”
Setpoint speed value, supplied by the Simulation [FC10] block.
“RD_addressHW-ID” of type “HW_SUBMODULE
The hardware ID required for reading data from the SINAMICS G120 is
forwarded to the LADDR input parameter of the “DPRD_DAT” instruction via
this parameter. For more detail see chapter 6.3.1.
“RD_addressHW-ID” of type “HW_SUBMODULE
The hardware ID required for writing data to the SINAMICS G120 is forwarded
to the LADDR input parameter of the “DPWR_DAT” instruction via this
parameter. For more detail see chapter 6.3.1.
