Counter function
This function sets the count type and start operation to start counting.
To start counting, turn on Set SW gate (b2 of Process data output "Control word").
When Set SW gate is turned on, SW gate active (b2 of Process data input "Counter status") and Internal gate active (b5 of
Process data input "Counter status") turn on.
When Reset SW gate (b10 of Process data output "Control word") is turned on, the counting stops.
The value of Counter value when the counting starts differs depending on the setting of the parameter "Counter behaviour
internal gate".

Description
Performs counting between the lower limit value (-2147483648) and upper
limit value (2147483647). When the value goes below the lower limit value,
the counting continues from the upper limit value and when it exceeds the
upper limit value, the counting continues from the lower limit value.
Performs counting between Load value and End value - 1. The counting
stops when the value exceeds End value - 1.
It is used to perform up counting only.
Performs counting between the "Load value" and "End value + 1". The
counting stops when the value exceeds End value + 1.
It is used to perform down counting only.
Performs counting between the lower limit value (-2147483648) and upper
limit value (2147483647). The counting stops when the value exceeds the
upper limit value or goes below the lower limit value.
Performs counting between Load value and End value - 1. When the value
exceeds End value - 1, the counting continues from Load value.
It is used to perform up counting only.
Performs counting between the "Load value" and "End value + 1". When the
value exceeds End value + 1, the counting continues from Load value.
It is used to perform down counting only.
Performs counting between the lower limit value (-2147483648) and upper
limit value (2147483647). When the value exceeds the upper limit value or
goes below the lower limit value, the counting continues from Load value.
Description
The counting starts from Counter value.
The value of Load value is stored in Counter value and the counting starts.
