0000 The function block is not active. The Activate input is FALSE. Activate the function block by setting Activate to TRUE.

8000 The function block is in a normal operating state. The muting process is not active (S_MutingActive = SAFEFALSE). The safety-related equipment of the zone of operation signals the defined safe state (S_AOPD_In = SAFETRUE). The enable signal is active (S_AOPD_Out = SAFETRUE). 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.

8001 The block was activated. The start-up inhibit of the function block is active. Perform a reset on the function block to exit the active start-up inhibit for the function block.

8002 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). To exit the active start-up inhibit for the function block, perform a reset on the function block once you have removed the request for the safety-related function at S_AOPD_In.

8005 The muting process is not active (S_MutingActive = SAFEFALSE). The safety-related equipment of the zone of operation signals the defined safe state (S_AOPD_In = SAFETRUE). The enable signal is not active (S_AOPD_Out = SAFEFALSE). This state is completed after one cycle of the Safety PLC. 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.

8011 The muting process was requested (S_MutingSwitch11 = SAFETRUE and S_MutingSwitch12 = SAFEFALSE). DiscTimeEntry monitoring until muting of the second muting sensor and MaxMutingTime monitoring are started. 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.

8012 The muting process is active (S_MutingSwitch11 = SAFETRUE and S_MutingSwitch12 = SAFETRUE). MaxMutingTime monitoring is running. The safety-related equipment of the zone of operation is not evaluated. If S_MutingSwitch11 and/or S_MutingSwitch12 change(s) from SAFETRUE to SAFEFALSE, the muting process is complete. 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.

8311 The muting process was requested (S_MutingSwitch11 = SAFEFALSE and S_MutingSwitch12 = SAFETRUE).
