2MLR-CPUH/T | Honeywell | High Speed CPU Module

The Honeywell 2MLR-CPUH/T is a high-speed CPU module designed for MasterLogic-200 PLC systems. Equipped with 7 MB of program memory and 16 MB of flash memory, it provides fast instruction processing and supports up to 372 rack slots across 31 expansion bases to manage large-scale industrial control tasks.

Program Execution and Instruction Handling

The CPU supports flexible program execution methods, including cyclic scanning, time-driven interrupts, and internal memory interrupts. Programming can be written in Ladder Diagram (LD), Sequential Function Chart (SFC), and Structured Text (ST), with Instruction List (IL) supported for view-only operations.

I/O processing accommodates both scan-synchronous batch processing (refresh method) and direct I/O manipulation triggered by specific program instructions.

System Scale and Communication Capacity

The module manages up to 128,000 points of network and remote I/O using Smart I/O assemblies. Operating on an internal backplane current draw of 1173 mA, it provides the core processing capacity required for expansive MasterLogic-200 automation architectures.
