Here, the call still remaining in OB1 is displayed:
CALL FB2, DB110(
Note
Owing to this measure, a shorter cycle time is achieved in OB1, because the static parameter
values need not be copied in the instance DB in each OB1 cycle.
The savings of this variant:
The cyclic copying effort of 3 integer values and 4 ANY parameters with respect to the instance
DB, which results from 3 time loading of a constant with a 3-time transfer in the instance data
block. In case of each ANY transfer, constants are loaded in the data block 4 times with
subsequent transfer.
