CompactLogix (1769) Selection Guide

Allen-Bradley is the manufacturer of the CompactLogix (1769) platforms, which are designed to provide a single integrated control architecture, a common programming software environment, and communication support for sequential, motion, drives, and process control. A CompactLogix (1769) system uses connections to establish a communication link across multiple hardware platforms. For instance, a connection can be between a controller to local/remote I/O modules or between a controller to remote/local communication modules. These connections are resource allocations that provide more reliable communications between the hardware platforms than unconnected messages.

A typical 1769 CompactLogix system consists of a CompactLogix Controller within the 1769 series and 1769 Compact I/O modules. In such a system, the 1769 CompactLogix controller is always the leftmost module. The controller is required to be within four modules of the CompactLogix system power supply. Some 1769 I/O modules may be placed up to eight modules away from the system’s power supply.

Therefore, the 1769 Logix platform combines the benefits of a common network, a common control engine, and a common programming environment in a small footprint with exceptional performance. With the 1769 Compact I/O modules, the CompactLogix (1769) system can support simple to more complex Integrated Motions, with unprecedented scalability and power. The platform is ideal for providing Logix solutions to applications that require system-connected and standalone control over the EtherNet/IP, DeviceNet, or ControlNet networks.
