SPEC 200 MICRO Control Interfacing

For migration of SPEC 200 MICRO control to

I/A

Series systems, the Control Processor 30

interfaces via a single or redundant I/A Series

Fieldbus with the SPEC 200 MICRO Control

Integrator subsystem. This subsystem consists of

individual Control Integrators, and Fieldbus Isolators

attached within the SPEC 200 MICRO rack (NCM or

SPEC 200 2ANU).

Control is via the software resident in the Control

Integrator and in the SPEC 200 MICRO I/O

Equipment Control Blocks (ECBs) operating at the

CP level.

Figure 9 illustrates a typical configuration

with multiple Control Integrators in the SPEC 200

MICRO subsystem. (Refer to PSS 21H-7R2 B3

SPEC

200 MICRO Control Integrators for additional

information.)

Control Processor 30 Upgrade

Upgrading a Control Processor 10, Tank

Processor

10, or Display Processor 10 to a CP30

involves:

• Replacing the existing Control Processor with a

CP30

• Upgrading the software license

• Modifying the System Configurator to identify the

CP30

• Loading existing compounds to the CP30
