Opening and closing HW gate
You open and close the HW gate of the relevant counter by applying or removing the
corresponding signals to or from the inputs 1I0 and 1I1 (counter 1) and/or 2I0 and 2I1
(counter 2).
Opening HW gate (level controlled)
Applying signal to input 1I0 (2I0)
Closing HW gate (level controlled)
Removing signal from input 1I0 (2I0)
Opening HW gate (edge controlled)
Applying positive edge to input 1I0 (2I0)
Closing HW gate (edge controlled)
Applying positive edge to input 1I1 (2I1)
When the HW gate opens the counter resumes counting from the current counter status.
Terminating counting process with the gate stop function
In addition you can end the count process when counting with the SW gate or HW gate by
means of the gate stop function of the relevant counter. For this purpose you set the
GATE_STP input parameter of the FC CNT_CTRL.
