Counter.
Reset Function
A Digital Input configured to have Reset functionality will reset the Counter to zero
on a rising edge (Reset Rising Edge, Function 05) or falling edge (Reset Falling
Edge, Function 06) of the Digital Input signal.
To reset a Counter with Function 05 or 06, the Software Enable Reset Bit must
be set to 1. A Counter can also be reset by using the “Software Reset Bit” in CIO.
Setting this bit to ‘1’ causes a forced reset of the corresponding Counter.
Refer to 3-6
for detailed information about resetting Counters.
