Allen-Bradley 1756-M08SE is an 8-axis SERCOS interface module for ControlLogix that serves as the bridge between a ControlLogix processor and SERCOS servo drives. The module enables up to eight axes on a single SERCOS network and uses a fiber-optic link for robust, real-time communication; it is available in the Series B variant (1756-M08SE-B). It is part of Rockwell Automation's 1756 Motion modules and is designed to plug into a ControlLogix chassis backplane to support coordinated multi-axis motion. Firmware for this module has been released up to version 38.001, reflecting ongoing Rockwell support for the 1756-M08SE.
