When configuring the 1P 252 closed-loop control module,
for speed measurement so that the actual count is interrogated by the 1P 240. Furthermore,
during initialization the 1/0 address and the assigned channel of the 1P 240 must also be specified.
The 1P 240 is configured by calling function block FB 173 in restart organization blocks OB21 and
OB22. In this mode, both channels are configured simultaneously; a second mode on the 1P 240 is
therefore not possible.
