SPECTRUM Migration Interfacing

The Control Processor 30 interfaces with a

SPECTRUM Migration Integrator subsystem via a

single or redundant I/A Series Fieldbus and a

Fieldbus Processor (FBP) with built-in FBP isolator

located within the subsystem. There are four different

FBP integrators to accommodate Unit Control

Modules (UCM), Field Input/Output Units (FIO),

Universal Field Multiplexers (UFM), and Universal

Input/Output Units (UIO).

The CP30 control strategy can include any of

following SPECTRUM configurations:

• a single SPECTRUM Migration Integrator

subsystem

• multiple types of SPECTRUM Migration

Integrator subsystems

• Fieldbus Modules (FBMs) and/or other Fieldbus-

based process interface subsystems along with

the SPECTRUM Integrator subsystem(s)

Control is via the software resident in the FBP

Integrator and in the SPECTRUM I/O Equipment

Control Blocks (ECBs) operating at the CP level.

Figure 7 illustrates a typical configuration with

multiple types of Integrator subsystems with nests of

I/O cards. (Refer to PSS 21H-7Q1 B3 SPECTRUM

Migration Integrators for additional information.)
