FAQ
FAQ
Q1: What is the primary function of the 1756-L55M13 controller?
The module is a ControlLogix Logix5555 processor designed for industrial automation and PLC control applications.
Q2: How much memory does the controller provide?
It includes 1.5 MB of user memory and 208 KB of I/O memory.
Q3: Does the 1756-L55M13 support Ethernet communication directly?
No. Native Ethernet requires additional communication modules such as 1756-ENBT or 1756-EN2T. The onboard port is RS-232 serial.
Q4: Which batteries are compatible with this processor?
Compatible backup batteries include the 1756-BA1 and 1756-BATM battery modules.
Q5: Is conformal coating included on the 1756-L55M13?
No. Allen-Bradley models ending with “K” generally indicate conformal coating versions. A Reddit discussion specifically notes that “K is conformal coating.”
Q6: Is the controller still actively manufactured?
No. The 1756-L55M13 has been discontinued by Rockwell Automation.
Q7: Which software versions support the controller?
The controller is supported by RSLogix 5000 version 8.02 or later.
Q8: What generation is the L55 controller within the ControlLogix platform?
The L55 belongs to the early Logix5555 generation preceding the L6x, L7x, and modern 5580/L8x controllers. Community discussions describe it as part of the original ControlLogix controller architecture.
