The 1769-L35CR is a Modular CompactLogix 5370 L3 Programmable Automation Controller (PAC) controller. This programmable controller has an available user memory of 1.5 MB, integrated communication ports of 1 ControlNet, 1 RS232 that supports DF1 or ASCII protocol.
The 1769-L35CR supports installation of Thirty (30) 1769 Compact I/O modules, 3 Expansion I/O banks with 2 expansion cables. It has a power supply distance rating of 4 modules and supports programming and configuration using RSLogix 5000 programming software.
The controller is supplied with default firmware revision of 1.x. This revision must be modified to match version of your RSLogix5000 software instance. For example, should you have RSLogix5000 software, version 13, upgrade your CompactLogix controller firmware to revision 13.x.
