12.4 Parameterising 2/4xcounter module
12.4.1 Parameter data
The operating mode of the 2/4xcounter (e.g. 2 x 32−bit counter or 4 x 16−bit
counter) can be determined by assigning each channel (counter 0 and counter 1)
a mode via the parameter data.
(
Stop!
Depending on the mode setting, the terminal assignment of the
counter module changes!
For the 2/4xcounter two 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 counter module is parameterised via the
indices 3001
h
... 3010
h
(max. 4 counter modules). The parameter data are stored
in the subindex 1.
Parameter setting via CoDeSys:
The max. 4 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.
