ASi#xx_F-IN1&2 Sensor value: Safety-related signal from the code sequence of
a two-channel sensor
Monitoring of safety-related
AS-i input slaves
ASi#xx_F-INc Input terminal signal of the ASIsafe input slave for the moni‐
toring functions.
If monitoring function "AS‑i 2F‑DI" is used:
Monitoring function "AS‑i 2F‑DI" is used instead of an input cell
if you want to diagnose both the input terminal signals of the
ASIsafe input slave.
ASI#xx_F-OUTc Signal, for example, from an AS-i safety monitor or from an‐
other MSS 3RK3
Representation of a safety-re‐
lated AS‑i output
ASI#xx_AUXm Modulated, non-safety-related auxiliary control signal
Slot3_ASI#xx(AB)-Qc Master call from AS-i master to the simulated non-safety-rela‐
ted AS-i slave of the MSS 3RK3
Simulation of non-safety-rela‐
ted AS‑i slaves
Slot3_ASI#xx-Qy.z Master call from AS‑i master to the simulated non-safety-rela‐
ted AS-i slave (CTT2) of the MSS 3RK3

Explanation Terminal designation output
cells in Safety ES
Simulation of non-safety-re‐
lated AS‑i slaves
Sensor signal from MSS 3RK3 to AS‑i master: Non-safety-rela‐
ted AS‑i output data range of the simulated AS-i slave desig‐
nates "non-safety-related" output
Slot3_ASI#xx(AB)-Sc
Sensor signal from MSS 3RK3 to AS‑i master: Determines bit
position in CTT2 frame for device diagnostics (see Chapter
"Diagnosis using AS-Interface (CTT2 protocol) (Page 298)").
Slot3_ASI#xx-Sy.z
Simulation of safety-related
AS‑i input slaves
Sensor signal from MSS 3RK3 to AS‑i master that can be eval‐
uated by an AS-i safety monitor
Slot3_ASI#xx-F-S1&2
Setting/resetting of safety-re‐
lated AS‑i outputs
Sensor signal from MSS 3RK3 to AS‑i master that can be eval‐
uated by an AS-i output.
Slot3_ASI#xx-F-Qc
m: Auxiliary signal 1 or 2
xx: AS-i address
(AB): A or B can be entered here if the monitored slave is an A/B slave. This identier is omitted for standard slaves. MSS 3RK3
supports only standard slaves for CTT2.
c: Channel number of AS-i slave process image
c*: The process image of the master call may contain more channels than the slave prole of the corresponding AS-i slave. The
channels addressed here are not processed on the AS-i slave but can be used for special solutions.
y.z: Denes bit position in CTT2 frame
Operation
6.5 Connecting to the AS-i master via AS-Interface
