Honeywell 2MLI-CPUS/P-CC – High-Performance CPU Controller Module | Experion PKS Platform
Engineering Background
The Honeywell 2MLI-CPUS/P-CC is a central processing unit module designed for deployment within Honeywell’s Experion PKS (Process Knowledge System) distributed control architecture. Experion PKS is one of the most widely adopted DCS platforms in the global process industries, trusted in refining, petrochemical, power generation, and advanced manufacturing environments where deterministic control, high availability, and deep integration with safety instrumented systems are non-negotiable requirements.
Product Positioning
This CPU module serves as the computational core of the Experion PKS controller chassis, executing control strategies, managing I/O communication, and maintaining real-time process data exchange with the supervisory network. It is engineered for continuous-duty industrial operation and is a direct replacement or expansion component for existing Experion PKS installations. Procurement engineers sourcing this part for MRO, capital project, or system upgrade purposes will find it fully compatible with standard Experion PKS chassis and backplane configurations.

System Architecture & Signal Flow
Within the Experion PKS architecture, the 2MLI-CPUS/P-CC occupies the CPU slot of the C300 or equivalent controller chassis. Control strategies authored in Control Builder are downloaded to the CPU, which executes them cyclically. Process values are acquired from I/O modules via the chassis backplane and transmitted upstream to the Experion Server via FTE (dual-ring Ethernet). Operator stations, historian servers, and safety systems communicate with the CPU through the Experion network fabric, enabling integrated alarm management, continuous historian archiving, and SIS coordination.
Typical Signal Flow:
Field Instruments → Series C / CIOM I/O Modules → Chassis Backplane → 2MLI-CPUS/P-CC CPU → FTE Network → Experion Server → Operator Stations / Historian / Safety Systems

Technical FAQ
Q: Is the 2MLI-CPUS/P-CC compatible with both C300 and legacy C200 controller chassis?
A: This module is designed for the Experion PKS C300 controller family. Compatibility with C200 chassis should be verified against Honeywell’s compatibility matrix prior to installation.
Q: Can this CPU module operate in a simplex (non-redundant) configuration?
A: Yes. The 2MLI-CPUS/P-CC can be deployed as a standalone simplex CPU. Redundancy requires a matched secondary CPU module and appropriate chassis slot configuration.
Q: What firmware version is pre-loaded?
A: Firmware versions vary by unit. Konmask will disclose the firmware revision upon request before shipment. Firmware upgrades are performed via Honeywell’s standard Control Builder upgrade procedure.
Q: Is this module RoHS compliant?
A: Honeywell Experion PKS modules manufactured after 2006 comply with RoHS Directive 2002/95/EC. Please confirm the specific unit’s date code with Konmask if RoHS documentation is required for your project.
Q: Do you provide installation support?
A: Konmask provides pre-sales technical consultation and post-sales documentation support. On-site installation services are available through our network of certified Honeywell system integrators.
