Section 3: System Components
This section contains the technical specifications and instruction for connecting the components
that make up the Safety Bus.
3.1 S81-F7011-1 Control Board
This board manages communication with the I/O modules. It monitors the communication ring and
receives all the signals coming from the I/O modules. It can be used in either mono or duplex con-
figuration mode, to increase the system availability.
