EC: Allen-Bradley CompactLogix 5380 Programmable Automation Controller

Machine & Embedded Control — PLCs, PACs, industrial PCs: The Allen-Bradley CompactLogix 5380 is a programmable automation controller that is ideal for small to mid-size applications that require low axis motion and I/O point counts. This is a Control Engineering 2017 Engineers’ Choice Awards Winner.

Manufacturers are under constant pressure to increase production speed and throughput while still maintaining quality. They also are facing increasing demands for smart machines. The new Allen-Bradley CompactLogix 5380 controller from Rockwell Automation can help meet these demands by providing more precision and connectivity, and up to 20% more application capacity than previous CompactLogix versions.

This controller is particularly helpful for high-speed packaging applications with up to 20 axes of motion, where fast response times are critical for keeping production running smoothly. When combined with the new Allen-Bradley Bulletin 5069 Compact I/O system, scheduled outputs improve I/O response time to as fast as 0.2 milliseconds. Event triggers from the I/O modules provide near-instantaneous task execution. The scheduled outputs and event triggers are new to the CompactLogix family, allowing engineers to design compact machines that achieve higher accuracy and precision.

In addition, a dual-configurable, 1-gigabit Ethernet port supports device-level-ring (DLR) topologies or the use of multiple IP addresses. The ability to create multiple IP addresses is especially useful for manufacturers seeking to establish network separation between plant-floor and enterprise-level traffic.

Diagnostic indicator lights display the status of communications, module health and I/O module activity. This allows operators to immediately understand problems without connecting the controller to a computer. In addition, built-in system and field power terminals reduce wiring to I/O modules.

The CompactLogix 5380 controller incorporates advanced security technologies and software features, including digitally signed and encrypted firmware, controller-based change detection, and audit logging.

As with other Logix controllers, engineers use the Rockwell Software Studio 5000 design software to configure the CompactLogix 5380 controller and develop all elements of their control system. Data can be defined once and reused across the entire Studio 5000 environment to speed development and commissioning.
