Status Indicators

Indicator State Description

24V DC On 24V DC operating voltage present.

Off No operating voltage.

RUN On This is the normal status of the controller.

A routine, which has been loaded into the controller, is executed.

The controller processes input and output signals, carries out communication, and

performs hardware and software tests.

Flashing The controller is in STOP mode and is not executing a routine.

All system outputs are reset.

STOP mode can be triggered by setting the Emergency stop system variable to TRUE

in the routine, or by direct command from the programming software.

Off The controller is in ERROR_STOP mode (see ERROR).

ERROR On

• A hardware error has been detected by the controller. The controller goes to

ERROR_STOP mode and the execution of the routine is halted. Hardware errors

are errors in the controller, errors in one or more of the digital input and output

modules, or errors in the counters.

• A software error in the operating system has been detected by the controller.

• The watchdog has reported an error due to exceeded cycle time.

All system outputs will be reset and the controller ceases all hardware and

software tests. The controller can only be restarted by a command from the

programming software.

Off No errors are detected.

PROGress On The upload of a new controller configuration is in progress.

Flashing The upload of a new operating system into the nonvolatile ROM is in progress.

Off No upload of controller configuration or operating system in progress.

FORCE On The controller is executing a routine (RUN) and FORCE mode is activated by the user.

Flashing The controller is in STOP mode, but Forcing has been initiated and will be activated

when the controller is started.

Off Forcing is OFF.

FAULT On

• The routine (logic) has caused an error.

• The controller configuration is faulty.

• The upload of a new operating system was not successful and the operating

system is corrupted.

Flashing An error has occurred during a nonvolatile ROM write cycle.

One or more I/O errors have occurred.

Off None of the above errors has occurred.

OSL Flashing Emergency Operating System Loader is active.

BL Flashing Boot Loader unable to load operating system or unable to start COMM operating
