Product Overview

The ZCP270 (P0926CP) is a high-performance control processor for the Foxboro I/A Series DCS, acting as the “brain” of the control station. It executes advanced control strategies, manages communications with Fieldbus Modules (FBMs), and interfaces with the high-speed “The Mesh” network.

Designed for high-availability environments, the ZCP270 supports optional redundancy, enabling continuous process regulation even during hardware faults. Its robust microprocessor architecture handles large I/O counts and complex computations with high-speed determinism.

Technical Specifications

Key Features and System Capabilities

• Advanced Control Algorithms
  Supports block-type algorithms including PID, signal characterization, and complex logic sequences for industrial automation.

• Redundancy Management
  Optional redundant configuration enables seamless “bumpless” transfer to a backup processor during primary unit failures.

• Time Synchronization
  Network time protocol support ensures millisecond-accurate timestamps for alarms and events across the DCS.

• Direct Fieldbus Integration
  Connects directly to 200 Series FBMs via redundant Fieldbus paths for high-speed, reliable process data transmission.

Technical FAQ

Q: How does the ZCP270 differ from the CP60 model?
A: The ZCP270 features the 100 Mbps “The Mesh” network, offering higher data throughput, lower latency, a more compact form factor, and lower power consumption compared to the Nodebus-based CP60.

Q: Does the P0926CP require a specific baseplate?
A: Yes. It must be mounted on a specialized 200 Series Control Processor baseplate (e.g., P0926KE) that provides power and communication connections for both primary and redundant operation.
