Simulator Control for Modicon Quantum CPU

Introduction

The dialog box is shown if the simulator is simulating a CPU from the Modicon Quantum family.

Representation of the dialog box:

CPU Front Plate

The virtual CPU front plate shows the current state of the CPU in a one line display:

Text in the display	The simulated CPU is in state...	Meaning
Init	INIT (Initialization)	This display is shown for a very short time while the simulator is starting. It is quickly replaced by one of the following displays.
UnCfg	NOCONF (no configuration)	No user project loaded or the loaded project is invalid.
Idle	IDLE	The project loaded on the CPU has not been started or reset with the Reset button.
Stop	STOPPED	No project is running. However, the loaded project was in RUN state at least once.
Run	RUN	A project with at least one task is running.
Halt	HALT	An error has occurred in the project. The simulated CPU must be reinitialized or reset using the Reset button.
Err	ERROR	An unrecoverable detected error has occurred in the project. This means communication is no longer possible. The simulated CPU must be reset using the Reset button.

Key Switch

By clicking the switch symbol, various switch positions can be simulated:

Switch position	Switch position on real CPU	Meaning
	Start	CPU unlocked: Project can be loaded. CPU can be started or stopped.
	Mem Prt	CPU locked: Project cannot be loaded. As opposed to the key switch on a real CPU, the CPU can be started or stopped in this position.
-	Stop	This switch position of a real CPU is not supported by the simulator.

Events

With this button, you can open and close the event dialog box.

The button is shown if I/O events are defined in the project currently loaded (if the project uses event tasks).

Reset

With this button, you can reset the simulated CPU. This corresponds to a cold start of the CPU (the connection between Control Expert and the simulator is broken, project variables are reset and the simulator goes in RUN (if auto start is activated) or in STOP (if auto start is deactivated)).

Reset corresponds to the reset button on a real CPU.

Power Cycle

With this button, you execute a power cycle (power off / power on) for the simulated CPU. This corresponds to a warm start of the CPU (the connection between Control Expert and the simulator is broken and the current project variables remain).

A power cycle corresponds to a power off and power on of a real power supply.

Simulation

Dialog box fields: Host PC name: DNS name of the host PC for the simulator. If the PC has multiple network cards, only the first is shown. Host IP address: TCP/IP address of the host PC for the simulator. If the PC has multiple network cards, only the first is shown. Project name: Name of the project loaded in the simulator.

Clients Connected

The list shows current clients connected with the PC (PCs which are connected via TCP/IP with the host PC of the simulator). The DNS name and TCP/IP address are shown for each client.
