Serial interfaces of the BUCs from the
redundancy controller
The M/C connector on each BUC includes the serial interface
of the BUC. Although the redundancy controller plugs into
this connector, the redundancy controller uses relay contacts to
communicate with the BUC.
You can access the serial interface of each BUC via the
14-way BUC 1 Serial or BUC 2 Serial connector on the
redundancy controller. These connectors are suitable for
temporary connection of a PC or Hand-held Controller 6560
as they have the same RS232 serial pin connections as the
M/C connector on the BUC.
The RS485 serial interfaces for both BUCs are included in the
19-way Auxiliary I/O connector interface of the redundancy
controller for remote monitor and control applications via the
Remote Controller 6570.
