Parameter
Parameter 1: current value of counter. This function is used to get the current
value of the counter.
Parameter 2: preset value of counter.
Input
Input 1: control input
Input
2: start value after counter is reset. When condition is satisfied, the
counting starts with 1; when condition is not satisfied, the counting starts with 0.
Input
3: plus-minus input. When condition is satisfied, the counter is
incremented; when condition is not satisfied, the counter is decremented.

If X4.0 is turned on, the counting will start with 1. If X4.1 is turned
on, the counter will decrease the count. When X2.5 has been turnd on
sixteen times, the output is Y1.4. X4.2 is the reset signal, to clear the
counter output. When X2.5 has been turned on five times, the value

When X2.5 is switched on and off 100 times, counter 0 is on, and the
signal is output to Y1.4. When X2.6 is switched on, the counter 0
counts with 1 after being reset; otherwise, the counter 0 counts with 0.
When X2.7 is switched off, the count is incremented; otherwise, the
count is decremented. When X2.8 is switched on, the counter 0 is reset.
