Allocation of I/O Channels
If a safety function is equipped with redundant instrumentation, it is recommended
for availability reasons to distribute the signals to different I/O modules wherever
practical.
Communication Interfaces
The AC 800M HI comprises peer-to-peer communication via the control network;
the communication is certified for safety critical use. Actually this function is a
“peer-to-multiple-peer” communication, i.e. data made available for communication
in one controller, can be read from multiple controllers.
This peer-to-peer communication can be established by using the MMS control
modules designed for this purpose, for more details, see Software Architecture on
page 76.
Other available communication interfaces are certified interference free, i.e. they
can be used in the AC 800M HI and the data communicated on them can be used in
both SIL and non-SIL Applications, but only for non safety critical functions.
For information on available communication interfaces refer to the user manual AC
800M 5.1 Communication Protocols, 3BSE035982* page 39.
