CANopen

CANopen - CANopen is a CAN-based higher layer protocol. It was developed as a standardized embedded network with highly flexible configuration capabilities. CANopen was designed for motion-oriented machine control networks, such as handling systems. By now it is used in many various fields, such as medical equipment, off-road vehicles, maritime electronics, public transportation, building automation, etc.

CAN-do Cable Solutions for Many Applications - Previously, automobiles utilized harnesses (many wires wrapped together) to directly wire individual devices, such as a brake pedal to the brake lights, creating a jumble of wires throughout the vehicle. Using as few as two wires, a CAN system connects the engine management ECU...

Fieldbus – Competent People will be at a Premium

Whatever digital fieldbus is your preference, if one wishes to maximise personal marketability it is time to think about gaining the competencies required to implement the technology.

Few would remember the last watershed in instrumentation, that is the change from pneumatics to electronics. Unfortunately I do and recollect it really hit home hard. At the time we had Scientific Instrument Makers who were responsible for the pneumatics and all...

Highway Addressable Remote Transducer Protocol (HART)

HART - The Premier Tool for Asset Management - Cut downtime and improve profits with the tools you already have - Do more with less. That’s the mantra of many industries today in North America or anywhere...

Industrial Ethernet

Industrial Ethernet - The use of Ethernet as an industrial network is a subject for which still very little documentation is available. This publication focuses entirely on this type of usage of Ethernet, and how this relates to the operation of Ethernet. A difference between an office-user of Ethernet and an industrial user of Ethernet is that the former is not interested in (seemingly trivial) details of internal Ethernet operation, while the latter must sometimes know...

MODBUS

Modbus has been around for years and is utilised comprehensively by Industry.

The following technical information is from Moore Industries-Pacific, Inc.
Using MODBUS for Process Control and Automation - MODBUS is the most popular industrial protocol being used today, for good reasons. It is simple, inexpensive, universal and easy to use. Even though MODBUS has been around for nearly 30 years, almost all major industrial instrumentation and automation equipment vendors continue to...

Profibus

PROFIBUS - This multidrop technology has been available for a number of years and is particularly suitable in the manufacturing environment. Does not have Control in the field option at present. Particularly favoured in Germany where it was developed. Lots of technical information can be found at this excellent Profibus site.  You have to register to get to it.

Why should you Choose Intrinsic Safety rather than Flameproof or FNICO for Fieldbus Applications?

The answer here is “why not” choose Intrinsic Safety since a fieldbus power supply is required for Exd, whilst a Fieldbus Non Incendive Concept (FNICO) power supply is required for FNICO (Zone 2 only) and a Fieldbus Intrinsically Safe Concept (FISCO) power supply for Zone 1.

Zone 0 applications can be accommodated by additional hardware and use of the Entity concept.The Entity concept limits...
