Configuring
When configuring the
1P
252 closed-loop control module, YOU must
W
the
configuring switches —
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.
