Applications that use closed-loop control often require communication networks that provide deterministic, real-time control of data transmission. This means the network guarantees that a message will be transmitted, or an event will be responded to, in a specified, predictable period of time — not faster or slower (deterministic) — and that the message will be transmitted […]

The CANopen over EtherCAT (CoE) protocol allows devices equipped with CANopen to be used on EtherCAT-based Industrial Ethernet networks. CANopen: Simple and low-cost CANopen is a communication protocol based on the CAN (Controller Area Network) physical communication standard. In the OSI communication model, CAN specifies the physical and data link layers, while CANopen addresses the […]

When sensors, actuators, and other lower-level components are used in a functional safety capacity, AS-Interface Safety at Work offers a simple, efficient, bus network for monitoring these safety devices — alongside standard, non-safety devices — on the AS-Interface cable. Recall that actuator-sensor interface (AS-Interface, or simply AS-I) is a master-slave bus that operates at the […]
