Beckhoff's distributed controllers

A conveyor line is usually run from a central cabinet; Beckhoff wants more of that control mounted on the conveyor itself. The company introduced its EP741x motor-driven roller controllers at MODEX 2026 in Atlanta. (beckhoff.com) The new EP741x units are EtherCAT I/O modules for powered conveyors, and Beckhoff said they support 24-volt and 48-volt brushless direct-current motors from different manufacturers, including motorized rollers and flat “pancake” motors. The company said the modules are available with or without integrated safety functions. (beckhoff.com) Instead of routing every motor and sensor back to one main panel, Beckhoff said the controllers can be distributed along the conveyor and linked in a cascade. The company said that layout cuts wiring work, lowers system costs, and fits the modules into the C-channel of conveyor frames. (beckhoff.com) Motor-driven roller conveyors use small motors inside individual rollers, so each zone can move cartons independently. That architecture is common in parcel, e-commerce, and warehouse systems because operators can add or reconfigure zones without rebuilding an entire conveyor line. (control.com) What changes here is where the control lives. Beckhoff is moving logic, wiring connections, and some safety functions closer to the rollers, rather than relying as heavily on a central programmable logic controller cabinet. (beckhoff.com) The safety version includes Safe Torque Off and Safe Stop 1 over Fail-safe over EtherCAT, Beckhoff said, which lets operators break a conveyor into smaller safety zones. That means one section can stop for maintenance or a jam while other sections keep running, if the system is designed for it. (beckhoff.com) Beckhoff is also pitching the EP741x as a vendor-agnostic controller in a market where conveyor components are often tied to specific motor suppliers. The company said the modules use standard M8 and M12 connectors and come in two-channel and four-channel versions. (control.com) The broader warehouse automation industry has been pushing toward more modular controls as operators add capacity in phases instead of building one fixed line and leaving it unchanged for years. Beckhoff’s MODEX 2026 pitch paired the EP741x with other cabinet-free and distributed automation products aimed at material handling. (beckhoff.com) The immediate test is whether system builders adopt the EP741x beyond trade-show demos. If they do, more of the conveyor’s “brain” will move out of the cabinet and onto the line itself. (automation.com)
