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.

8401 Init state (if closed and locked)
The function block has been activated and initiated. The safety equipment is closed (S_Guard = SAFETRUE) and locked (S_GuardLock = SAFETRUE) with the guard locking.
If a start-up inhibit is active (set with S_StartReset = SAFEFALSE), the FB waits for a rising edge at input Reset. Otherwise, the FB changes to state 8000 after one cycle of the Sicherheitssteuerung.
Output Ready is TRUE. The outputs S_GuardLocked and S_UnlockGuard show SAFEFALSE.
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 show FALSE. Perform an FB reset if this is indicated via ResetRequest = TRUE.
Otherwise switch the reset signal to FALSE.

8801 Init state (if not 8401)
The function block has been activated and initiated. At least one of the input signals at S_Guard or S_GuardLock is SAFEFALSE. This means the safety equipment is either not closed and/or not locked.
Output Ready is TRUE. SafetyDemand = TRUE indicates that the safety chain is interrupted.
The outputs S_GuardLocked and S_UnlockGuard show SAFEFALSE. The other outputs show FALSE. Close and lock the safety equipment. The FB then changes to state 8401.

8000 Guard Closed and Locked state
The safety equipment is closed (S_Guard = SAFETRUE) and locked (S_GuardLock = SAFETRUE) with the guard locking.
The S_GuardLocked output is SAFETRUE and Ready is TRUE.
Output S_UnlockGuard is SAFEFALSE, the other outputs show 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.

8010 Wait for Unlocked state
The safety equipment is closed (S_Guard = SAFETRUE) and locked (S_GuardLock = SAFETRUE) with the guard locking. A request to unlock the guard locking has been detected via a rising edge following a constant TRUE at input UnlockRequest while the defined safe state of the zone of operation is reported (S_SafetyActive = SAFETRUE). The unlock request has not yet been acknowledged by the safety equipment. The FB waits for the SAFETRUE signal at input S_GuardLock.
Output Ready is TRUE. S_UnlockGuard is SAFETRUE to request the unlocking.
The S_GuardLocked output is SAFEFALSE. The other outputs show FALSE. No measures required. S_GuardLock must switch to SAFETRUE within 2 seconds.

8822 Guard Open and Unlocked state
The safety equipment is open (S_Guard = SAFEFALSE). Although it is already unlocked, a request to unlock the guard locking has been detected at input UnlockRequest while the defined safe state of the zone of operation is reported (S_SafetyActive = SAFETRUE).
Output Ready is TRUE. SafetyDemand = TRUE indicates that the safety chain is interrupted. S_UnlockGuard is SAFETRUE to request the unlocking.
The S_GuardLocked output is SAFEFALSE. The other outputs show FALSE. You can open the safety equipment or cancel the unlock request to enable the area protected by the safety equipment for normal operation.

8832 Guard Closed but Unlocked state
The safety equipment is closed (S_Guard = SAFETRUE) but unlocked (S_GuardLock = SAFEFALSE). Although unlocked, a request to unlock the guard locking has been detected at input UnlockRequest while the defined safe state of the zone of operation is reported (S_SafetyActive = SAFETRUE).
Output Ready is TRUE. SafetyDemand = TRUE indicates that the safety chain is interrupted. S_UnlockGuard is SAFETRUE to request the unlocking.
The S_GuardLocked output is SAFEFALSE. The other outputs show FALSE. You can open the safety equipment or cancel the unlock request to enable the area protected by the safety equipment for normal operation.

8812 Wait for Operator state
The FB waits that the operator either closes and locks the safety equipment or requests to open the safety equipment (unlock request).
Output Ready is TRUE. SafetyDemand = TRUE indicates that the safety chain is interrupted.
The outputs S_GuardLocked and S_UnlockGuard are SAFEFALSE. The other outputs show FALSE. Perform one of the following:

To enable the area protected by the safety equipment for normal operation: Close and lock the safety equipment (that S_Guard and S_GuardLock become = SAFETRUE) and cancel the unlock request.

Request unlocking (by applying a rising edge at input UnlockRequest) and then open the safety equipment.

8430 Wait for Reset state
The safety equipment is closed (S_Guard = SAFETRUE) and locked (S_GuardLock = SAFETRUE) again. The restart inhibit of the function block (set by S_AutoReset = SAFEFALSE) is active.
The FB now waits for 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 outputs S_GuardLocked and S_UnlockGuard are SAFEFALSE. The other outputs show FALSE. Perform an FB reset if this is indicated via ResetRequest = TRUE.
Otherwise switch the reset signal to FALSE. The FB then changes to state C031.
