Reaction to gate start
You can configure the following reaction to gate start:
Reaction
Set to start value
Continue with current value
Note
The parameter is only effective when you have configured a HW gate.
Set function of DI
With the parameter assignment of a digital input, you specify which function the digital input
triggers when switched.
You can select from the following options:
Function of a digital input
Gate start/stop (level-triggered)
Gate start (edge-triggered)
Gate stop (edge-triggered)
Synchronization
Enable synchronization at signal N
Digital input without function
Note
Each function, except "Digital input without function", can be used only once per counter and
can no longer be selected for the other digital inputs in each case.

Meaning
When the gate is opened, the counter value is set to the start
value.
When the gate is opened, counting is continued with the last
counter value.
Meaning
The level at the respective digital input opens and closes the
HW gate.
The configured edge at the respective digital input opens the
HW gate.
The configured edge at the respective digital input closes the
HW gate.
The configured edge at the respective digital input sets the
counter to the start value.
The active level at the respective digital input enables syn-
chronization of the counter at signal N.
No technological function is assigned to the respective digital
input.
You can read the signal status of the digital input via the feed-
back interface.
