FAQ
FAQ
Q1: What is the primary function of the 1756-L55M23 controller?
The 1756-L55M23 is a ControlLogix Logix5555 processor module used for industrial automation and PLC control applications.
Q2: How much memory does the controller provide?
The controller includes 1.5 MB RAM, 1.5 MB nonvolatile memory, and 208 KB of I/O memory.
Q3: Does the 1756-L55M23 have built-in Ethernet?
No. The onboard communication interface is RS-232 serial. EtherNet/IP or other industrial networks require separate communication modules such as 1756-ENBT or 1756-EN2T.
Q4: Which communication networks are supported?
The controller supports EtherNet/IP, ControlNet, and DeviceNet through compatible communication modules.
Q5: Which batteries are compatible with this processor?
Compatible battery modules include the 1756-BA1 and 1756-BATM.
Q6: Is the 1756-L55M23 still manufactured?
No. Rockwell Automation has discontinued the 1756-L55M23 processor.
Q7: What generation is the L55 series within the ControlLogix platform?
The L55 belongs to the early Logix5555 generation preceding the L6x, L7x, and modern L8x/5580 families. PLC community discussions commonly identify it as one of the original ControlLogix controller generations.
Q8: What software versions support the controller?
The controller is supported by RSLogix 5000 software and legacy Logix5000 platforms commonly used with ControlLogix L55 processors.
