Process Control Integration & Fieldbus Processing
The 2MLR-CPUH/T handles real-time execution of control logic across 128,000 field network and remote I/O channels. Operating via 4-20 mA HART loop protocol field devices, FOUNDATION Fieldbus, and Profibus PA network gateways integrated into the backplane chassis, the processor isolates logic execution from field noise. Internal execution routines utilize 7 MB of program RAM and 16 MB of non-volatile flash memory to deliver sub-millisecond task timing while maintaining channel-to-channel isolation and fault diagnostics.
Frequently Asked Questions
Q: What are the primary program execution methods supported by the 2MLR-CPUH/T CPU module?
A: The module executes program logic via cyclic scan processing, time-driven interrupts, and internal memory event interrupts.
Q: How does the processor handle I/O updates during execution cycles?
A: It supports both scan-synchronous batch processing (the standard memory refresh method) and direct I/O refresh triggered directly by software instructions.
Q: What is the backplane current demand for the 2MLR-CPUH/T module?
A: The unit draws a nominal current of 1173 mA from the 5 VDC backplane bus rail.
Field Installation Guidelines
- Isolate and disconnect all system power sources feeding the base chassis rack prior to inserting or removing the 2MLR-CPUH/T processor module.
- Align the rear circuit card guide pins with the backplane slot guide channels and seat the module firmly into position until top and bottom locking levers latch.
- Attach high-speed communication interfaces to designated front-panel connectors using shielded, twisted-pair cable assemblies.
- Verify that the rack mounting frame connects directly to the panel enclosure central earthing bar using a low-impedance ground wire to shield processor electronics from high-frequency interference.
