Safety Instructions
The following tables list the safety application instructions that are certified for
use in SIL 2 or SIL 3 applications.
ATTENTION: These safety instructions are the only instructions that can be
used in the safety tasks in SIL 2 or SIL 3 applications.
Table 5 - General Safety-application Instructions
Mnemonic Name Purpose
CROUT Configurable Redundant Output Controls and monitors redundant outputs.
DCA Dual Channel Input - Analog (integer
version)
Monitors two analog values for deviation and range tolerance.
DCAF Dual Channel Input - Analog (floating
point version)
DCS Dual Channel Input - Stop Monitors dual-input safety devices whose main purpose is to provide a stop function, such as an
E-stop, light curtain, or gate switch.
DCST Dual Channel Input - Stop With Test 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.
DCSTL Dual Channel Input - Stop With Test
and Lock
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.
DCSTM Dual Channel Input - Stop With Test
and Mute
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.
DCM Dual Channel Input - Monitor Monitors dual-input safety devices.
DCSRT Dual Channel Input - Start Energizes dual-input safety devices whose main function is to start a machine safely, for example an enable pendant.
SMAT Safety Mat Indicates whether the safety mat is occupied.
THRSe Two-Hand Run Station – Enhanced 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.
TSAM Two Sensor Asymmetrical Muting Automatically disables the protective function of a light curtain temporarily, by using two muting sensors that are
arranged asymmetrically.
TSSM Two Sensor Symmetrical Muting Automatically disables the protective function of a light curtain temporarily, by using two muting sensors that are
arranged symmetrically.
FSBM Four Sensor Bi-directional Muting 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.
