Alicat devices are compatible with a variety of analog, serial, or industrial communication protocols for easy data collection and analysis. Options include analog (4-20 mA, 0-10 Vdc, 0-5 Vdc, or 1-5 Vdc), ASCII and Modbus RTU over RS-232, ASCII and Modbus RTU over RS-485, Profibus, DeviceNet, EtherNet/IP, Modbus TCP/IP, and EtherCAT.
In this article, we provide answers to common questions about EtherCAT.
Introduced in 2003 by Beckhoff Automation, EtherCAT is a high performance industrial Ethernet technology with a flexible topology. EtherCAT’s key functional principle lies in how its nodes process Ethernet frames. Each node reads data addressed to it and writes its data back to the frame, all while the frame is moving downstream. This leads to improved bandwidth utilization and eliminates the need for switches and hubs.
