Siemens SIRIUS 3RK3 - Monitoring of Non-Safety-Related AS-I Slaves

6.5.7.9 Monitoring of non-safety-related AS-i slaves
The MSS 3RK3 with AS-i interface can monitor up to 14 non-safety-related AS-i slaves of type
"standard slave," "A/B slave," or "CTT3 slave." In this way, non-safety-related signals that are
exchanged between the master and the non-safety-related AS-i slaves can be fed into the logic
of the MSS 3RK3.
The following CTT3 pro󹪝les are supported:
• IO-Code 0x7, ID-Code 0xA, ID2-Code 0x7 (S-7.A.7):
A/B slave with 4-bit input and 4-bit output image
• IO-Code 0x7, ID-Code 0xA, ID2-Code 0xA (S-7.A.A):
A/B slave with 8-bit input and 8-bit output image
Note
Further AS-i slave pro󹪝les:
All slave pro󹪝les that are not supported are interpreted as "4I / 4O standard slaves" or as "4I / 3O
A/B slaves."
Terminal designation in Safety ES
Signals from the AS-i master to the AS-i slave (Q) or from the AS-i slave to the AS-i master (IN) can
be incorporated in the interconnection logic via an input cell and interconnected in the Safety
ES.
Note
To be able to interconnect a non-safety-related AS-i slave, the "Monitor non safe I/O" checkbox
must be selected in the subsystem (navigation window) in the properties of the slave.
The designations of the input cells for this are as follows:
Terminal designation in the input cell Explanation
ASI#xx(AB)_INc Sensor input
ASI#xx(AB)_Qc Output (master call)
ASI#xx(AB)_Qc* Master call to the channel that is not part of the slave pro󹪝le
xx: AS‑i address
(AB): A or B can be entered here if the monitored slave is an A/B slave. This identi󹪝er is omitted for standard
slaves.
c: Channel number of AS-i slave process image
c*: The process image of the master call may contain more channels than the slave pro󹪝le of the
corresponding AS-i slave. The channels addressed here are not processed on the AS-i slave but can be used
in the logic.
