Honeywell 900CP1-0100 ControlEdge PLC Modules

Configured for high-speed deterministic execution in Honeywell ControlEdge PLC platforms, the Honeywell 900CP1-0100 (900CP1-0100 Control Processor Module) provides direct physical/electrical execution. Driven by a dual-core 32-bit ARM Cortex-A9 processor running at 667 MHz, this CPU module coordinates real-time data processing, logic execution, and backplane I/O communications. The hardware incorporates 512 MB RAM, 256 MB Flash memory, and nonvolatile memory retainment to govern up to 23,041 combined analog and digital channels across 12 expansion racks.

Suffix Breakdown & Model Matrix

• 900CP1: Base Control Processor Module architecture within the Honeywell ControlEdge PLC hardware family.
• -0100: Hardware revision and feature set indicator designating standard dual-core ARM Cortex-A9 CPU configuration with controller redundancy support.

Hardware Specifications

Industrial PLC Control & Backplane Velocity

The module executes deterministic logic routines while driving backplane bus communication velocity across local and expansion racks. Internal firmware flash compatibility enables remote firmware updates and cold/warm reboot procedures over secured Ethernet links. Hardware architecture supports 1 ms real-time clock resolution and automated CPU watchdog resets to preserve system determinism. Dual EtherNet/IP and Modbus TCP network protocols execute deterministic data exchanges between the CPU, remote I/O nodes, and SCADA supervisory control layers.

Frequently Asked Questions

Q: How does the nonvolatile memory protect real-time system data during an unannounced power loss?

A: Integrated nonvolatile retention circuits preserve internal system state variables and real-time clock data for approximately two weeks following a complete loss of 5 VDC backplane power.

Q: What expansion limits apply when configuring redundant controller topologies?

A: Redundant configurations support up to 12 expansion I/O racks connected via dedicated redundant interface modules, governing a maximum system capacity of 23,041 I/O points.

Field Installation Guidelines

Ensure main backplane power is de-energized before inserting or removing the CPU module from the ControlEdge rack slot. Align the module card edges with the enclosure guide rails and push firmly until the retention lever locks completely into place. Connect shielded Ethernet communication cables to the front RJ45 ports, maintaining at least 300 mm clearance from high-voltage AC lines to prevent signal interference. Connect the main rack grounding lug directly to the central cabinet earth bus using a short, heavy-gauge copper strap.
