Reset Signals
For every Counter a reset of the Counter Value to zero can be triggered by the fol-
lowing Sources:
• Software Reset Bit
• Z-signal
In order for the Z-Signal to trigger a Reset this must be enabled by the Software
Reset Enable Bit.
Software Reset Bit as Reset
Source
For every Counter the Software Reset Bit can be used to trigger a Reset. The Soft-
ware Reset Bit has priority over all other Reset Sources. Setting the Software
Reset Bit triggers a Reset in the next I/O Refresh Cycle.
Z-Input Signal as Reset
Source
If you want to use the Z-Signal of an incremental encoder as a Reset Source this
must first be enabled in DM. Using the Z-Signal can be enabled for every Counter.
Software Reset Enable Bit
as Reset Enable Source
Resetting the Counter Value to zero by Z-Signal must be enabled. Enabling can be
done by setting the Software Reset Enable Bit in CIO for the corresponding Coun-
ter to 1.
