The function of the input no. 3 terminal I3).
Each pulse on this input increases the counter
no. 3, regardless of the function of the input.
The functions assigned to the input refer to the
control of the inputs configured to work in the
counter mode.
Default: NONE
NONE – no function
C1 SS, C2 SS – control of the main input counter modes).
An active signal at the input starts the counter and counting.
The counter is stopped at no signal at the input - the pulses
are not counted. The counter operation is controlled by the
input level.
C1 STA, C2 STA – start the counter. Edge control - input
signal starts the counter.
C1 STP, C2 STP – stop the counter. Edge control - input
signal stops the counter.
C1 RST, C2 RST – input signal resets the counter. The initial
value of the counter after a reset) depends on set counting
direction see the parameter CONSt) .
C2 DIR – change counting direction. During an active signal
the counting direction of the additional input of the counter
I2) is changed.
C12SS – control of the main input and the additional input
counter modes). An active signal at the input starts the
counters and counting the pulses. The counters are stopped
at no signal at the input - the pulses are not counted. The
counters are controlled by the level.
Note: C1 refers to the main input I1) and C2 refers to the
additional input I2).
