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 identifier 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 profile 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: Defines bit position in CTT2 frame

Explanation
Sensor value: Safety-related signal from the code sequence of
a two-channel sensor
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.
Signal, for example, from an AS-i safety monitor or from an‐
other MSS 3RK3
Modulated, non-safety-related auxiliary control signal
Master call from AS-i master to the simulated non-safety-rela‐
ted AS-i slave of the MSS 3RK3
Master call from AS‑i master to the simulated non-safety-rela‐
ted AS-i slave (CTT2) of the MSS 3RK3
Explanation
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
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)").
Sensor signal from MSS 3RK3 to AS‑i master that can be eval‐
uated by an AS-i safety monitor
Sensor signal from MSS 3RK3 to AS‑i master that can be eval‐
uated by an AS-i output.
