Precautions for Correct Use
This FB does not detect short-circuits in muting sensor signals or errors in the function applica-
tions that supply those signals. It interprets them as illegal muting sequences. Unintentional
muting must not be allowed under these conditions. Give attention to this during risk assess-
ment.
DiscTime11_12 TIME T#0s to T#4s T#0s A constant. It sets the maximum discrepancy time
between MutingSwitch11 and MutingSwitch12.
DiscTime21_22 TIME T#0s to T#4s T#0s A constant. It sets the maximum discrepancy time
between MutingSwitch21 and MutingSwitch22.
MaxMutingTime TIME T#0s to T#10min T#0s A constant. It sets the maximum time until completion of
the muting sequence. The timer starts when the muting
sensor first operates.
MutingEnable BOOL TRUE or FALSE FALSE A constant or a variable. It is a command from the control
system to enable starting muting as required in the
machine cycle. You can change this signal to OFF after
muting starts.
FALSE: Disables muting.
TRUE: Enables starting muting.
S_StartReset SAFEBOOL TRUE or FALSE FALSE Refer to Safety FB Common Input Variables on page 4-2.
Reset BOOL TRUE or FALSE FALSE Refer to Safety FB Common Input Variables on page 4-2.
*1. You must connect a SAFEBOOL variable (not a BOOL variable) depending on safety requirements.

S_AOPD_Out SAFEBOOL TRUE or FALSE FALSE This safety-related output gives the status of the protec-
tion devices that is being muted.
FALSE: Something has entered the AOPD protected
area and muting is disabled.
TRUE: Nothing has entered the AOPD protected area
and muting is enabled.
S_MutingActive SAFEBOOL TRUE or FALSE FALSE Gives the muting status.
FALSE: Muting is disabled.
TRUE: Muting is enabled.
Error BOOL TRUE or FALSE FALSE Refer to Safety FB Common Output Variables on page
