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.

8401 Init state
The FB has been activated (Activate = TRUE).
If a start-up inhibit is active (S_StartReset = SAFEFALSE), the FB waits for a rising edge at input Reset.
If no start-up inhibit is active (S_StartReset = SAFETRUE), the FB changes to state 8002 after one cycle of the Sicherheitssteuerung.
Output Ready is TRUE.
Output ResetRequest depends on the signal at input Reset:

If Reset = FALSE, ResetRequest = TRUE to indicate the required reset signal.

If Reset = TRUE, ResetRequest = FALSE as the reset signal must first be switched to FALSE.

The other outputs are SAFEFALSE or FALSE. If the start-up inhibit is active: Perform an FB reset if this is indicated via ResetRequest = TRUE.
Otherwise switch the reset signal to FALSE. The FB then changes to state C001.

8002 Safe state
The safety function is activated. The FB evaluates the signal at input S_AOPD_In.
Output Ready is TRUE.
The other outputs are SAFEFALSE or FALSE. Switch input S_AOPD_In to SAFETRUE.

8000 AOPD Free state
The function block is in a normal operating state. The muting process is not active. There is no safety demand from the safety-related equipment at the zone of operation (S_AOPD_In = SAFETRUE).
As a result, the enable signal is active (S_AOPD_Out = SAFETRUE). Output Ready is TRUE and the other outputs show SAFEFALSE or FALSE. In case of an unexpected combination at the function block inputs relative to the physical input of the sensors, verify the connected hardware if required and correct the error.

8402 Safety Demand AOPD 1 state
A previously detected safety demand has been removed (S_AOPD_In is SAFETRUE again) or the cause of a previously detected error has been removed.
The FB waits for the acknowledgment by the operator in the form of a rising edge at input Reset.
Output Ready is TRUE.
Output ResetRequest depends on the signal at input Reset:

If Reset = FALSE, ResetRequest = TRUE to indicate the required reset signal.

If Reset = TRUE, ResetRequest = FALSE as the reset signal must first be switched to FALSE.

The other outputs are SAFEFALSE or FALSE. Perform an FB reset if this is indicated via ResetRequest = TRUE to exit the active (mandatory) restart inhibit for the function block.
Otherwise switch the reset signal to FALSE. The FB then changes to state C011.

8802 Safety Demand AOPD 2 state
The muting process was not active but the safety-related equipment of the zone of operation signals the non-safe state (S_AOPD_In = SAFEFALSE).
Output Ready and output SafetyDemand are TRUE.
The other outputs are SAFEFALSE or FALSE. Remove the request for the safety-related function at S_AOPD_In.

S_MutingSwitch22 = SAFEFALSE
The sequence is in starting phase and MaxMutingTime monitoring has started.
The enable signal is active (S_AOPD_Out = SAFETRUE). Output Ready is TRUE.
The other outputs are SAFEFALSE or FALSE. In case of an unexpected combination at the function block inputs relative to the physical input of the sensors, verify the connected hardware if required and correct the error.

S_MutingSwitch11 and S_MutingSwitch12 are SAFETRUE.
MaxMutingTime monitoring is running. The safety-related equipment of the zone of operation is not evaluated.
The enable signal is active (S_AOPD_Out = SAFETRUE). S_MutingActive = SAFETRUE indicates the active muting process. 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 the connected hardware if required and correct the error.

S_MutingSwitch11 = SAFEFALSE
S_MutingSwitch12 = SAFEFALSE
S_MutingSwitch21 = SAFEFALSE
S_MutingSwitch22 = SAFETRUE
The sequence is in starting phase and MaxMutingTime monitoring has started.

8200 Override Active state
During a muting error (state CYx4), the operator requests the override function (SAFETRUE signal at the S_StartStopOverride input). The override time monitoring (set at input MaxOverrideTime) is started.
The override function is active. The safety-related equipment is deactivated for as long as the override operation is active.
OverridePossible is TRUE to indicate the override operation can be requested by the operator. Output OverrideActive is TRUE.
The enable signal is active (S_AOPD_Out = SAFETRUE). S_MutingActive = SAFEFALSE indicates the muting process is no longer active. 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 the connected hardware if required and correct the error.

8832 Override Interrupt state
During an active override operation, the signal at the S_StartStopOverride input switches to SAFEFALSE.
The override function is inactive again but the override time monitoring is continued.
OverridePossible is TRUE to indicate the override operation can be requested by the operator.
The enable signal is active (S_AOPD_Out = SAFETRUE). S_MutingActive = SAFEFALSE indicates the muting process is no longer active. Output Ready is TRUE.
