ControlLogix Processor Execution and Memory Architecture
The 1756-L55M14 integrates the Logix5555 processor with a 1756-L55 base processor and 1756-M14 memory module. The controller executes ControlLogix application programs while managing I/O data exchange through the chassis backplane bus.
The processor supports up to 128,000 total I/O points with analog capacity of 4,000 input points and 2,000 output points. The 3.5 MB memory allocation provides application storage for controller programs, tag data, and system configuration parameters.
Backplane Bus Communication and Firmware Compatibility
The 1756-L55M14 communicates with ControlLogix I/O and communication modules through the backplane bus interface. The processor architecture supports deterministic data exchange between controller resources and installed chassis modules.
Firmware flash compatibility allows supported controller revisions to be maintained within the ControlLogix platform. The module can interface with compatible communication modules supporting EtherNet/IP, ControlNet, DeviceNet, and other ControlLogix network configurations.

A: The module requires 1.23 A at 5 VDC and 14 mA at 24 VDC from the ControlLogix chassis backplane.
Field Installation Guidelines
Install the 1756-L55M14 processor module into a compatible ControlLogix chassis slot and verify chassis power supply capacity before startup. Confirm correct seating of the processor and memory module connections during installation.
Route communication and control wiring separately from high-voltage power conductors to reduce electromagnetic interference. Maintain proper grounding practices for the ControlLogix chassis and connected field devices.
Install compatible battery components according to controller configuration requirements. Verify firmware revision compatibility, processor configuration, memory allocation, and communication module settings before commissioning.
