S_MutingActive output

Output for the status of the muting operation.

Data type: SAFEBOOL

Connection: Connect the S_MutingActive output to an output terminal of your application (for a muting lamp, for example), either directly or via other safety-related functions/function blocks.

The signal (S_MutingActive) may only control the process directly if this does not adversely affect the safety-related function.

WARNING

Unintended machine operation

Verify that the S_MutingActive signal only controls the process directly if this does not adversely affect the safety-related function.

Validate the overall safety-related function, including the start-up behavior of the process, and thoroughly test the application.

Value Description

SAFETRUE This indicates that muting is active. The following conditions must be met.

The function block has been activated (input Activate = TRUE)

and the muting has been activated by an interruption of the light beams of both sensors located before the safety-related equipment. Refer to the information concerning the material flow direction in the function block overview in this context.

and the active muting has not yet been completed by the second parallel sensor pair. The muting operation is complete if at least one muting sensor located behind the safety-related equipment switches from TRUE back to FALSE.
Refer to the information concerning the material flow direction in the function block overview in this context.

and the function block has not detected an error.

Note
If muting is active (S_MutingActive = SAFETRUE), the light beam of the safety-related equipment may be interrupted. The S_AOPD_Out output remains SAFETRUE.

SAFEFALSE Muting is not active. This may be due to one of the following reasons:

Muting has not been activated by the muting sensors

or the function block is not activated (input Activate = FALSE)

or the function block has detected an error.

The muting sequence is invalid

or the monitoring time set at MaxMutingTime has elapsed.

Note
If muting is not active, an interruption of the light beam of the safety-related equipment will cause the S_AOPD_Out output to be switched to the defined safe state (SAFEFALSE).
