This document is a comparison of common characteristics of 1794-L34 Logix controllers in the FlexLogix Selection Guide. It describes the features and characteristics of different models of controllers such as 1756 ControlLogix, 1769 CompactLogix, 1789 SoftLogix5800, and 1794 FlexLogix.
The document serves as a selection guide for the Allen-Bradley FlexLogix 1794-L34 controller. It provides an overview of the Logix platform architecture, which integrates sequential, drives, motion, and process control into a single system using RSLogix 5000 software.
The guide walks users through specific selection steps for building a system, including choosing I/O modules (FLEX and FLEX Ex), selecting network communication cards (EtherNet/IP, ControlNet, DeviceNet), determining controller requirements based on tasks and memory, planning power supplies, and configuring DIN rails.
| User Memory (Standard) | 512 Kbytes |
|---|---|
| Controller Tasks | 32 tasks (only 1 continuous) |
| Event Task Support | supports all event triggers |
| Communication Ports | 1 port RS-232 serial (DF1 or ASCII) |
The controller supports relay ladder, structured text, function block, and sequential function chart.
Each FlexLogix controller can support up to 8 local I/O modules.
