3.3.3 Executing steps
Execution of steps is described below.
Outline of the step execution function
"To execute a step" means to simulate the program one instruction at a time. While
a step (one instruction) is executed, a mnemonic list is displayed and the line cur-
rently being executed can be verified.
When specification of the break condition or setting of break points is combined, the
operation status of the program from the specified input to the specified output can
be checked at each step, so a location of nonconformity can be quickly detected.
There are five step execution methods available: "executing a step continuously ",
"executing a step once", "executing steps at a high speed", "executing a step con-
tinuously in the reverse direction" and "executing a step once in the reverse direc-
tion".
Mnemonic list window
When a step is executed, the displayed device values and ON/OFF status are
changed continuously on the ladder monitor window according to the operation
speed. The current position is also scrolled according to the operation speed.
In addition, the mnemonic list window is opened and the mnemonic line currently
being executed is highlighted.
