Diagnostic codes

The hexadecimal diagnostic codes listed here are output as WORD data type at the DiagCode output of the function block.

Code (hex) Description Options for remedy

0000 The function block is not activated. The Activate input is FALSE.
Depending on the connection of Activate, the inactive function block can also indicate an error in the connected periphery. Activate the function block by switching Activate to TRUE.
Correct the error in the periphery according to the device description.

8000 The emergency-stop control device is not activated (S_EStopIn = SAFETRUE). No measures required.

8001 The function block is activated. This state of the function block is completed after one cycle of the Safety PLC. No measures required.

8002 The start-up inhibit is specified with S_StartReset = SAFEFALSE.

The emergency-stop control device is activated (S_EStopIn = SAFEFALSE).

or the wiring is damaged or disconnected

or the safety-related input device, to which the emergency-stop control device is connected, is switched off or inoperable.

Deactivate the activated emergency-stop control device.

In case of a deactivated emergency-stop control device verify the wiring and the safety-related device to which the emergency-stop control device is connected.

8003 The emergency-stop control device is deactivated (S_EStopIn = SAFETRUE).
The restart inhibit of the function block is active. Perform a reset on the function block.

8004 The emergency-stop control device is activated (S_EStopIn = SAFEFALSE).

The emergency-stop control device is activated (S_EStopIn = SAFEFALSE).

or the wiring is damaged or disconnected

or the safety-related input device, to which the emergency-stop control device is connected, is switched off or inoperable.

Deactivate the activated emergency-stop control device and then perform a reset if S_AutoReset = SAFEFALSE.

In case of a deactivated emergency-stop control device verify the wiring and the safety-related device to which the emergency-stop control device is connected.

8005 The emergency-stop control device is deactivated again. The restart inhibit of the function block is active (S_AutoReset = SAFEFALSE). Perform a reset on the function block.

C001 A permanent TRUE was detected at Reset when waiting for the reset signal.
Previous states have been 8001 » 8002 » 8003. This means C001 may occur during the startup of the emergency-stop application after activating the function block.

Switch Reset = FALSE.

Verify the reset control device and its wiring.

C002 A permanent TRUE was detected at Reset when waiting for the reset signal.
Previous states have been 8004 » 8005. This means C002 may occur during running operation after deactivating the previously activated emergency-stop control device.

Switch Reset = FALSE.

Verify the reset control device and its wiring.
