7.13.3. Addition and Subtraction (Cycle Method)
The value of a numeric variable can be increased by adding a positive value or it can be decreased by adding
a negative value. Minimum and maximum values can be defined as limits. This method has the feature that
if the value hits the limit (min/max), the value will be stepped to the other end of the interval.
Command and Response
ç CALL·/CTRL/VARS/V<loc>:cycle(<operand>;<min>;<max>)
æ mO·/CTRL/VARS/V<loc>:cycle
Parameters
Parameter Parameter description
<loc> The location of the variable
<operand> The value that is added to the variable
<min> The lowest allowed value (optional)
<max> The highest allowed value (optional)
If the calculated value is beyond the limit (min/max), the value will be stepped to the other end of the interval.
