4-2 Debugging Operation
The Ladder Engine has the execution mode for operating from the
[CX-Simulator Debug Console] as well as the modes in the CS/CJ/CP-series
PLC. Changing the execution mode from the [CX-Simulator Debug Console]
allows more detailed debugging.
4-2-1 CS/CJ/CP-series PLC's Modes and Execution Mode
The Ladder Engine of the CX-Simulator performs the same operation as the
actual PLC. Thus it has the actual PLC's modes (Program/Monitor/Run).
Relationship between Actual PLC's Modes and Execution Mode
The table below shows the relationship between the actual PLC's modes and
the Execution Mode

Same as the Moni-
tor mode.
Changed only by the
CX-Programmer
setting.
Note
The Ladder Engine runs in the Monitor mode. A Run operation turns the mode
to Monitor even when the mode is changed to Run from the CX-Programmer.
Mode Change from CX-Programmer
Changing the mode from the CX-Programmer will change the execution mode
of the Ladder Engine as follows.
•
Program mode
→
Monitor/Run mode
: Continuous Run
•
Monitor/Run mode
→
Program mode
: Stop mode
•
Monitor mode
→
Run mode
: No change
•

→
Monitor mode
: No change
Execution mode and CX-Simulator Connection
Selecting [Disconnect] in the [Work CX-Simulator] window will automatically
turn the execution mode to the Stop mode. Changing the execution mode from
the [CX-Simulator Debug Console] or changing the mode from the
CX-Programmer can not be performed during Disconnect.
Change the execution mode after [Connect].
