Allen-Bradley 1756-M16SE Serco Interface Module

Allen‑Bradley 1756-M16SE is a ControlLogix 16‑axis SERCOS interface module that provides sixteen SERCOS servo channels to drives on a Rockwell Automation SERCOS network. It installs in a 1756 ControlLogix I/O chassis, enabling direct communication between a Logix controller and up to 16 servo drives over the SERCOS protocol. This module is part of the 1756‑MxxSE family and is commonly paired with Kinetix motion drives to execute synchronized multi‑axis motion from a single controller. Rockwell documentation lists the 1756‑M16SE (Catalog 1756‑M16SE, Series A) among its SERCOS interface modules and notes firmware revisions such as 20.007, 21.001, and 38.001, reflecting ongoing support and improvements for motion control. In Studio 5000/Logix environments, the M16SE exposes axis configuration and drive mapping through its SERCOS interface, enabling coordinated control of multiple axes with standard motion instructions. Its 16‑axis capability makes it suitable for applications requiring parallel motion, such as multi‑axis conveyors, automated assembly lines, and precision positioning tasks where reliable, deterministic servo communication is essential within Rockwell’s motion ecosystem.
