The Allen-Bradley 1756-DMA31 ControlLogix drive module is used on SynchLink, a fiber optic communication link for distributed motion and drive systems based on PowerFlex 700S and ControlLogix systems. SynchLink can be used together with standard control network protocols such as Ethernet or ControlNet. This link is utilized for two specific applications: time synchronization and data transfer.
A 1756-DMA31 module resides on an Allen-Bradley ControlLogix chassis and connects directly to SynchLink. This ControlLogix SynchLink module is used for coordinated drive control, distribution motion control, and time synchronization. It serves as the physical interface between the ControlLogix backplane and the SynchLink fiber optic network.
The 1756-DMA31 is a single-slot module for interfacing with Reliance Electric DPS (Distributed Power System) drive equipment. Each module interfaces with a single PMI (power module interface) chassis. Within this system, the 1756-DMA31 performs velocity, position, and torque control functions for the connected drive equipment.
