CONSOLE FUNCTIONAL OPERATION
The OIS console is an operator interface with state of the art
CPU technology, a user friendly operator interface and a high
performance INFI 90 OPEN system interface.
The CPU is the key component in the OIS console. It is a DEC
AlphaStation 255 model 233. It contains memory, SCSI and
graphics cards. It also has two hard disk drives and a
CD-ROM.
The multibus cards use the backplane only for power, ground
and reset connections. Refer to Figure
for a block diagram
of the functions and connections of the OIS console and driver
cabinet.
The interface unit modules give the OIS console access to sys-
tem process data and communication data by interfacing it to
an INFI-NET or Plant Loop system. Three cards in the multi-
bus card cage make up the interface unit. They are the
IIMCL01 Multibus Communication Loop Termination Module,
