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 function block has been activated. The FB evaluates the signal applying to the inputs S_Button1 and S_Button2.
Output Ready is TRUE. The other outputs show SAFEFALSE or FALSE. No measures required.

8802 Buttons Released state
Both two-hand buttons are not actuated (S_Button1 = SAFEFALSE and S_Button2 = SAFEFALSE).
Outputs Ready and SafetyDemand are TRUE. The other outputs are SAFEFALSE or FALSE. To switch S_TwoHandOut to SAFETRUE, both two-hand buttons must be actuated.

8804 Button 1 Actuated state
Only two-hand button 1 is actuated (S_Button1 = SAFETRUE and S_Button2 = SAFEFALSE). The FB starts the monitoring timer.
Output Ready and output SafetyDemand are TRUE. The other outputs are SAFEFALSE or FALSE. To switch S_TwoHandOut to SAFETRUE, both two-hand buttons must be actuated.

8806 Button 2 Actuated state
Only two-hand button 2 is actuated (S_Button1 = SAFEFALSE and S_Button2 = SAFETRUE). The FB starts the monitoring timer.
Output Ready and output SafetyDemand are TRUE. The other outputs are SAFEFALSE or FALSE. To switch S_TwoHandOut to SAFETRUE, both two-hand buttons must be actuated.

8000 Buttons Actuated state
The function block is in a normal operating state. Both two-hand buttons are actuated (S_Button1 = SAFETRUE and S_Button2 = SAFETRUE). The buttons were pressed before the monitoring time expired.
The S_TwoHandOut output is SAFETRUE. Output Ready is TRUE. The other outputs are FALSE. In case of an unexpected combination at the function block inputs relative to the physical input of the sensors, verify S_Button1 and S_Button2 and the connected hardware.

8808 Button 2 Released state
Both two-hand buttons were actuated (S_TwoHandOut was switched to SAFETRUE). Then, two-hand button 2 has been released (S_Button2 = SAFEFALSE).
The S_TwoHandOut output is disabled (SAFEFALSE) again. Outputs Ready and SafetyDemand are TRUE. Output Error shows FALSE. Both two-hand buttons must not be actuated.
In case of an unexpected combination at the function block inputs relative to the physical input of the sensors, verify S_Button1 and S_Button2 and the connected hardware.

880A Button 1 Released state
Both two-hand buttons were actuated (S_TwoHandOut was switched to SAFETRUE). Then, two-hand button 1 has been released (S_Button1 = SAFEFALSE).
The S_TwoHandOut output is disabled (SAFEFALSE) again. Outputs Ready and SafetyDemand are TRUE. Output Error shows FALSE. Both two-hand buttons must not be actuated.
In case of an unexpected combination at the function block inputs relative to the physical input of the sensors, verify S_Button1 and S_Button2 and the connected hardware.

880C Locked Off state
In state 8808 or 880A, the S_TwoHandOut output was disabled (SAFEFALSE) again. After this, both two hand buttons must be detected released.
However, the value SAFETRUE is detected at the inputs S_Button1 and S_Button2.
The S_TwoHandOut output is SAFEFALSE. Outputs Ready and SafetyDemand are TRUE. Output Error shows FALSE.

Both two-hand buttons must not be actuated.

This state could indicate a wiring error.

880E Locked On state
In state 8804 or 8806, only one button was actuated. The FB expects that the other button is pressed as well. Instead, the other button was pressed and the one already pressed was released.
The S_TwoHandOut output is SAFEFALSE. Outputs Ready and SafetyDemand are TRUE. Output Error shows FALSE. Release both two-hand buttons as they must not be actuated.
