If the FB is called with ACT = 0, only the status
codes DONE, ERROR and STATUS are
updated.
LADDR INPUT WORD Module base address
When you configure the CP with STEP 7
hardware configuration, the module base
address is displayed in the configuration table.
Specify this address here.

The parameter indicates whether the
configuration data area was completely

Remember that it may be necessary to call the
FB several times depending on the size of the
configuration data area (in several cycles) until
the DONE parameter is set to 1 to signal
completion of the transfer.
