schneiderI/A Series® Hardware Control Processor 40

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 40 Upgrade

Upgrading a Control Processor 30, Control Processor 

10, Tank Processor 10, or Display Processor 10 to a 

CP40 involves:

• Replacing the existing Control Processor with a 

CP40

• Upgrading the software license

• Modifying the System Configurator to identify the 

CP40

• Loading existing compounds to the CP40

Specification Sheet (PSS) which describes the specific enclosure that is to be used.}

PHYSICAL SPECIFICATIONS

Configuration

Single-width processor module. The fault- tolerant 

version consists of two single-width processor 

modules with two interconnecting buses (X-bus and 

Z-bus).

Mass (Maximum)

1.7 kg (3.75 lb) for a single, non-fault-tolerant module.

Mounting

May be placed in any of the following mounting 

structure slots:

– 1 X 8 Mounting Structure 

– Industrial Enclosures (IE16 and IE32), 

Structural Foam or Metal

– Field Enclosure 8, Structural Foam or Metal 

In the fault-tolerant version, the two modules must be 

mounted in adjacent mounting structure slots with the 

two interconnecting buses.
