Procedures Section 3-2
Example:
Returning from an ST Program to the Calling Program or Instance
Note The Step Out command can be executed only in a ladder/ST program within
an instance.
■ Display when Operation is Paused by the Simulation Function
The color of the cursor (or arrow in an ST program) indicates whether an
operation has been paused in the Simulation Function Window, as well as
which operation has been paused.
Note (1) When Tools - Simulation - Always Display Current Execution Point
has been selected, the Simulator automatically scrolls the display to show
the paused point in the instance when performing Step Run or Continu-
ous Step Run operation.
(2) The color of the cursor (or arrow in an ST program), which indicates when
an operation has been paused in the Simulation Function Window, can
be changed from its default color.
To change the color, select Tools - Options and click the Appearance
Tab. Select Pause Simulator, Simulator Instruction Break, or Simulator IO
Break, and change the color for that condition.
■ Break Point Operation in an Instance
Execution can be paused automatically at the preset break point in the
instance. (In this case, the Step In operation cannot be used.)
Note When a break point is set for an instance, the break point is valid for that
instance only. (The break point is not valid for other instances created from
the same function block definition.)
