Diagnostic codes

Dieses Thema enthält die folgenden Abschnitte:

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

Status transitions and the corresponding conditions can be seen in the State machine diagram.

Status codes (except error codes)

Code (hex) Description Options for remedy

0000 Idle state
The function block is not activated. The Activate input is FALSE.
The outputs show SAFEFALSE or FALSE. Activate the function block by switching Activate to TRUE.

8001 Init state
The FB has been activated (Activate = TRUE).
If a start-up inhibit is active (S_StartReset = SAFEFALSE), the FB changes to state 8802. If no start-up inhibit is active (S_StartReset = SAFETRUE) and if the emergency stop control device is not activated (S_EStopIn = SAFETRUE), the FB changes to state 8000 after one cycle of the Sicherheitssteuerung.
Output Ready is TRUE, the enable output shows SAFEFALSE, the other outputs are FALSE. No measures required.

8802 Wait for S_EStopIn 1 state.
The FB is activated and initalized. It waits for the SAFETRUE signal at input S_EStopIn. The start-up inhibit is active (S_StartReset = SAFEFALSE).
As soon as S_EStopIn = SAFETRUE is detected, the FB changes to state 8402.
Output Ready is TRUE, the enable output shows SAFEFALSE, output SafetyDemand is TRUE to indicate that the safety chain is interrupted. The other outputs are FALSE.

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.

8402 Wait for Reset 1 state.
S_EStopIn = SAFETRUE has been detected (the emergency-stop control device is not pressed). The start-up inhibit is active and the FB waits for a rising edge at input Reset.
Output Ready is TRUE, the enable output shows SAFEFALSE, output ResetRequest is TRUE to indicate the required reset signal. The other outputs are FALSE. Perform a reset on the function block.

8804 Wait for S_EStopIn 2 state.
Safety request detected: S_EStopIn = SAFEFALSE (the emergency-stop control device is activated).
Output Ready is TRUE, the enable output shows SAFEFALSE, output SafetyDemand is TRUE to indicate that the safety chain is interrupted. The other outputs are FALSE.

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.

8404 Wait for Reset 2 state.
A detected safety request has been already been removed by deactivating the emergency-stop control device (S_EStopIn already switched back to SAFETRUE). The restart inhibit is active and the FB waits for a rising edge at input Reset.
Output Ready is TRUE, the enable output shows SAFEFALSE, output ResetRequest is TRUE to indicate the required reset signal. The other outputs are FALSE. Perform a reset on the function block.

8000 Safety Output Enabled state
The function block is activated and in normal operating state: No start-up/restart inhibit is active and the emergency-stop control device is not activated (S_EStopIn = SAFETRUE).
As a result, the S_EStopOut output is SAFETRUE, Ready is TRUE and the other outputs show FALSE. No measure required.

Error codes

Code (hex) Description Options for remedy

C010 Reset Error 1 state
A permanent TRUE was detected at Reset when waiting for the reset signal while S_EStopIn = SAFETRUE.
The previous states were 8001 » 8802 » 8402.
This means the error occurred during the startup of the emergency-stop application after activating the function block and the emergency-stop control device is not pressed. The start-up inhibit is active and the FB waits for a rising edge at input Reset.

Switch Reset = FALSE.

Verify the reset control device and its wiring.

C020 Reset Error 2 state
A permanent TRUE was detected at Reset when waiting for the reset signal while S_EStopIn = SAFETRUE.
The previous states were 8804 » 8404.
This means the error occurred during running operation: A detected safety request has been already been removed by deactivating the emergency-stop control device again. The restart inhibit is active and the FB waits for a rising edge at input Reset.

Switch Reset = FALSE.

Verify the reset control device and its wiring.
