12.6 Parameterising 1xcounter/16xdigital input module
12.6.1 Parameter data
The parameter data can be used to assign a mode to the internal counter and to
configure the digital input filter.
For the 1xcounter/16xdigital input, three bytes of parameter data are available,
which are assigned via SDOs.
Parameter setting via Global Drive Control (GDC):
Depending on the plug−in station, the module is parameterised via the indices
3001
h
... 3010x
h
(maximum 8 counter modules). The parameter data is stored in
the subindex 1.
Parameter setting via CoDeSys:
The max. 8 counter modules are addressed via index I3401
h
. The parameter data
are assigned in the subindices 1 ... 64 (4 bytes per subindex). The counter module
assigns 1 subindex.
