You should observe the following rules regarding the assignment of
function blocks to the time slot table and the processing table.
♦ Function blocks that can be combined to form a function group (with
a mutual task) should be processed in the same time slot.
♦ Function blocks should be processed in the fastest necessary time
slot, not in the fastest possible time slot.
♦ The sequence in which the function blocks are entered into the
processing table should correspond to the signal flow.
With the introduction of parameter P357<>0 (from V2.20) the pulse
frequency is no longer directly connected with the sampling frequency.
Changing the pulse frequency by halving it (P357 = 1) is only possible if
the Power Extension PIN F02 has been enabled (relevant for power
sections above 75 kW), see Chapter 11.10 "Power Extension PIN F02".
