If the muting sensors MutingSwitch11 (MS_11) and MutingSwitch12 (MS_12) are activated by the product
within the time DiscTime11_12, muting mode is activated (S_MutingActive = TRUE).

Muting mode remains active as long as MutingSwitch11 (MS_11) and MutingSwitch12 (MS_12) are activated
by the product. The product may pass through the light curtain without causing a machine stop.

Before muting sensors MutingSwitch11 (MS_11) and MutingSwitch12 (MS_12) are disabled, muting sensors
MutingSwitch21 (MS_21) and MutingSwitch22 (MS_22) must be activated. This ensures that muting mode
remains active. The time discrepancy between switching of MutingSwitch21 and MutingSwitch22 is moni-
tored by the time DiscTime21_22.
