CAN Controller Area Network in Automation

CAN (Controller Area Network) is a serial bus system, which was originally developed for automotive applications in the early 1980’s. The CAN protocol was internationally standardized in 1993 as ISO 11898-1 and comprises the data link layer of the seven layer ISO/OSI reference model.

CAN Controller Area Network in Automation

CANopen is a CAN-based higher layer protocol. It was developed as a standardized embedded network with highly flexible configuration capabilities.

In the year 1992, several companies founded the CAN in Automation (CiA) non-profit group, in order to provide technical, product and marketing information.

CANopen-based dust-filtering systems

CANopen-based dust-filtering systems

Hesch (Germany) has developed an industrial dust-filtering systems. The HE 5750 host-controller provides a CANopen NMT master interface to communicate to the sub-layered valve units operating the dust-filters. The entire system can be controlled by means of the Profibus or Modbus interfaces. The embedded filter control software supports the reduction of emission values and energy costs.

The valve controllers are uses to pulse solenoid valves in industrial dust extraction technology. They are controlled via an embedded CANopen network by means of the HE 5750 host-controller. The NMT slave units are attributed locally and technically to one filter chamber each. This concept adapts to any desired number of filter chambers and valves.

Safety and Health Standards – CSA

The Canadian Standards Association is a not-for-profit membership-based association serving business, industry, government and consumers in Canada and the global marketplace.

Safety and Health Standards – CSA

CSA Group works closely with leading independent agencies and associations to promote safety standards in North America and around the world.

CSA marks confirm that a product has been tested and has met the applicable standards for safety & performance as outlined by ANSI, UL, CSA, NSF and more.

CSA Marks & Labels for North America

Special inspection for electrical health care products – “Your electric health care product is tested against the provincial guidelines Field Approval of Health Care Equipment plus any applicable CSA Group health care product standard requirements.”

CE – Conformite Europeenne – Safety Standards

The CE marking is required for many products. It states that the product is assessed before being placed on the market and meets EU safety, health and environmental protection requirements.

CE marking – Enterprise and Industry

The CE marking (also known as CE mark) is a mandatory conformity mark on many products placed on the single market in the European Economic Area (EEA).

CE – Conformite Europeenne – Safety Standards

CE marking signifies that the product conforms with all EC directives that apply to it. For example, most electrical products must comply with the Low Voltage Directive and the EMC Directive; electrical toys must also comply with the Toy Safety Directive.

CE – European Economic Area – EEA – Safety mark

“It is the manufacturer’s responsibility to carry out the con- formity assessment, to set up the technical file, to issue the EC declaration of conformity and to affix CE marking on a product. Distributors must verify the presence of both the CE marking and the necessary supporting documentation. If the product is being imported from a third country, the importer has to verify that the manufacturer outside the EU has undertaken the necessary steps and that the documentation is available upon request.”
