Safety Instructions
ATTENTION: These safety instructions are the only instructions that can be
used in the safety tasks in SIL 2 or SIL 3 applications.
For the latest information on certified instructions, see our safety certificates
and revision release list at

The following tables list the safety application instructions that are certified for
use in SIL 2 or SIL 3 applications.
Purpose
Controls and monitors redundant outputs.
Monitors two analog values for deviation and range tolerance.
Monitors dual-input safety devices whose main purpose is to provide a stop function, such as an
E-stop, light curtain, or gate switch.
Monitors dual-input safety devices whose main purpose is to provide a stop function, such as an
E-stop, light curtain, or gate switch. It includes the added capability to initiate a functional test of the stop device.
Monitors dual-input safety devices whose main purpose is to provide a stop function, such as an
E-stop, light curtain, or gate switch. It includes the added capability to initiate a functional test of the stop device. It
can monitor a feedback signal from a safety device and issue a lock request to a safety device.
Monitors dual-input safety devices whose main purpose is to provide a stop function, such as an
E-stop, light curtain, or gate switch. It includes the added capability to initiate a functional test of the stop device and
the ability to mute the safety device.
Monitors dual-input safety devices.
Energizes dual-input safety devices whose main function is to start a machine safely, for example an enable pendant.
Indicates whether the safety mat is occupied.
Monitors two diverse safety inputs, one from a right-hand push button and one from a left-hand push button, to
control one output. Features configurable channel-to-channel discrepancy time and enhanced capability for
bypassing a two-hand run station.
Automatically disables the protective function of a light curtain temporarily, by using two muting sensors that are
arranged asymmetrically.
Automatically disables the protective function of a light curtain temporarily, by using two muting sensors that are
arranged symmetrically.
Automatically disables the protective function of a light curtain temporarily, by using four sensors that are arranged
sequentially before and after the sensing field of the light curtain.
