4-2-1 CS/CJ/CP-series PLC's Modes and Execution Mode

Relationship between Actual PLC's Modes and Execution Mode
Mode Change from CX-Programmer
Execution mode and CX-Simulator Connection
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.
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).
The table below shows the relationship between the actual PLC's modes and
the Execution Mode

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.
Changing the mode from the CX-Programmer will change the execution mode
of the Ladder Engine as follows.
• Program mode → Monitor/Run mode
• Monitor/Run mode → Program mode
• Monitor mode → Run mode
• Run mode → Monitor mode
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].
