The L23 CompactLogix Controller
All L23 models came with 512K of battery-backed (1769-BA) volatile memory, as well as 16 24vdc Digital Inputs and 16 24vdc Digital Outputs.
Each also came with a pre-installed 1769-ECR end cap and supported at least two local 1769 Compact I/O expansion modules.
The L23 had the same “Run Mode” key switch found on first and second generation CompactLogix controllers, as well as a 9 Pin D-Sub “Channel 0” isolated RS-232 Serial Port.
Like previous generations, the L23 could be programmed through its “Channel 0” port via a standard “Null Modem” serial cable (including the 1747-CP3 or 1756-CP3 cables.)
And also like previous generations, the L23 had the same “default communications” button which replaced (i.e. erased) the user's “Channel 0” settings with the controller's defaults when pressed.
In fact, aside from the missing CompactFlash Slot, and limit of 3 Tasks and 4 Programs, the L23 was nearly identical to the L3x controllers it was based on.
