. . If a fault occurs at the spur, the output switches off quickly reducing the current to 1 mA (fold back). The output returns to normal operation when the fault has been cleared. Even in the unlikely event of multiple concurrent short circuits, the additional current demanded of the fieldbus power supply is minimized.

Fieldbus is simply a means of communicating with input devices (sensors, switches, etc.) and output devices (valves, drives, indication lamps etc.) without the need to connect each individual device back to the controller (PLC, Industrial PC etc.). Therefore, overall, Fieldbus can reduce costs.

4416.254 Rev. 3 Enraf B.V. P.O. Box 812 Fieldbus interface 9 1 Introduction 1.1 About this manual This manual describes the fieldbus specifics for products in a fieldbus network addressed via CANopen DS301. 1.2 CAN-Bus The CAN bus (Controller Area Network) was originally developed for fast, economical data transmission in the automotive industry. Today, the This parameter is used for configuration of the fieldbus communication. Connecting the PSE Softstarter to the Fieldbus plug automatically enables fieldbus communication. To enable control of the softstarter using fieldbus, this parameter must be set to On. If Fieldbus Con-trol is set to OFF, fieldbus can only be used for monitoring softstarter data. Intelligent Fault Protection: Improved Availability for the Chemical Industry In the chemical industry, fieldbus technology must work under the most difficult of ambient conditions.

Several digital bus protocols have been developed and introduced into a variety of industries, including the power generation industry. Geraint Thomas from Control Techniques offers some insight into fieldbus systems, and explains how and why they benefit machine builders. Fieldbus systems have grown into an essential part of any device used today in homes and workplaces; from smart energy meters showing where we are using our electricity, to a printing machine that prints the daily newspapers.

Innovative Graphic Display is used for easy . commissioning, visual status & diagnostics. Commissioning . Capabilities • Set network address (including IP & Subnet mask for Ethernet) • Set baud rate • Set brightness • Set factory defaults. Visual Diagnostics • Shorted and open load detection Fieldbus is a digital two-way multidrop communication link between intelligent field devices. It is a local area network dedicated to industrial automation. It replaces centralized control networks with distributed control networks and links the isolated field devices such as smart sensors/ transducers/actuators/controllers.
