Explanation:
Sets a point variable P.
P <point number>
P 200
Sets a point variable P to 200.
The point variable can contain a point number as a variable, which can
be from 0 to 999. By using a movement command such as MOVA with
a P+ or P- statement, the number of steps required to create a repeating
program can be reduced.
• The contents of point variable P are retained even when the controller
power is turned off, but when the program is reset or when the pro-
gram reset is applied for example by switching the execution program,
the point variable P will be initialized to 0.
• Point variables P in a task are independent of those in other tasks. For
example, the definition and edited contents of a point variable used in
task 1 do not affect the point variable used in task 0.
