S_AOPD_In input

State-controlled input for the status of the safety-related equipment (e.g., light grid).

Data type: SAFEBOOL
Initial value: SAFEFALSE

Connection: Connect this input to an optoelectronic safety-related equipment (e.g., a light grid) connected to the Sicherheitssteuerung, either directly or via other safety-related functions/function blocks. Constant SAFETRUE or SAFEFALSE values are not permitted.

If the function block is activated (input Activate = TRUE), the possible values at this input lead to the following function block behavior:

Value	Description
SAFEFALSE	The light beam of the optoelectronic safety-related equipment is interrupted. Hinweis When muting is active (output S_MutingActive = SAFETRUE), the S_AOPD_Out output remains in the non-safe state SAFETRUE (e.g., "machine running"). Hinweis When muting is not active (output S_MutingActive = SAFEFALSE), the S_AOPD_Out output switches to the defined safe state SAFEFALSE (e.g., "stop machine").
SAFETRUE	The light beam of the optoelectronic safety-related equipment is not interrupted.

Single-channel or two-channel safety-related equipment?

Irrespective of whether there is a single-channel or two-channel connection between the safety-related equipment and the Sicherheitssteuerung, the S_AOPD_In input is only connected to one signal.

If a two-channel safety-related equipment is used, either the input channels of the safety-related input device must be parameterized accordingly or the SF_Equivalent or SF_Antivalent function blocks must be connected upstream for evaluating or monitoring the two-channel signal (e.g., SF_Equivalent function block for equivalence monitoring).
