Simulator Icon in the Toolbar

Introduction

After launching the simulators the simulator icon appears in the toolbar. This icon identifies the active simulator and displays the different states of the simulated PLC.

General Structure

The simulator icon is composed according to the following rules.

The background color represents the basic state.

Example	Color	Description
	green	normal operating mode
	yellow	PLC in HALT state
	red	PLC in ERROR state

A frame around the icon shows the active debug mode

Example	Color	Description
	blue	Debug mode is active, i.e. at least one breakpoint is set in the project, or there is at least one user task in debug mode.

The inner symbol shows the current PLC state, such as NOCONF, IDLE, STOPPED, RUN.

Symbol	The simulated PLC is in state...	Description
	NOCONF (no configuration)	No user project loaded or the loaded project is invalid or removed with the Clear command.
	IDLE	The project loaded on the PLC has not been started or reset with the Reset command button.
	STOPPED	No project is running.
	RUN	A project with at least one task is running.

The color of the inner symbol shows the connection state.

Example	Color	Description
	black	No TCP/IP client is connected.
	red	At least one TCP/IP client is connected.

Error States

Meaning of the symbols

Symbol	The simulated PLC is in state...	Description
	HALT	An error has occurred in the project. The simulated PLC must be re-initialized or reset using the Reset command button.
	ERROR	An fatal error has occurred in the project. This means communication is no longer possible. The simulated PLC must be reset using the Reset command button.

Internal States

The following symbols represent temporary internal states which should not be seen normally. It is not possible to recover from these states, so the PLC simulator must be closed and restarted again.

Symbol	The simulated PLC is in state...	Description
	POWER OFF	An internal error has occurred during the simulation of a PLC reset or power cycle.
	INIT	An internal error has occurred during the initialization of the PLC simulator.
	UNKNOWN	The PLC simulator has entered an unknown state.
