SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section explains the theory of operation for the operator
interface console. An operator uses the OIC console to monitor
and control the process through an OIS main console. For OIC
operating procedures, refer to the operation instruction.
The OIC console interfaces to INFI-NET and Plant Loop com-
munication highways through the OIS main console. It can
monitor and allow manual control of a process through color
graphics displays which show equipment status and process
state. Figure
shows a block diagram of the communication
process.
