CAN in Automation (CiA) is the international users’ and manufacturers’ group for the CAN network (Controller Area Network), internationally standardized in the ISO 11898 series. The nonprofit association was established in 1992. The aim is to provide an unbiased platform for future developments of the CAN protocol and to promote the image of the CAN technology. CiA supports all CAN applications from road vehicles via industrial machine control to medical devices and lift control systems. CiA is highly committed to international standardization submitting its specifications to international and national standardization bodies such as ISO and IEC as well as SAE and DIN, for example. CiA provides seminars and other education opportunities. Additionally, CiA organizes the international CAN Conference (iCC). Other services include the publication of the CAN Newsletter magazine and its online sister (https://www.can-newsletter.org).

The OPC Foundation is dedicated to ensuring interoperability in automation by creating and maintaining open specifications that standardize the communication of acquired process data, alarm and event records, historical data, and batch data to multi-vendor enterprise systems and between production devices. Production devices include sensors, instruments, PLCs, RTUs, DCSs, HMIs, historians, trending subsystems, alarm subsystems, and more as used in the process industry, manufacturing, and in acquiring and transporting oil, gas, & minerals.

ODVA is a global association whose members are comprised of the world’s leading automation companies. ODVA’s mission is to advance open, interoperable information and communication technologies in industrial automation. ODVA recognizes its media independent network protocol, the Common Industrial Protocol or “CIP™” – and the network adaptations of CIP – EtherNet/IP™, DeviceNet™, CompoNet™ and ControlNet™ – as its core technology and the primary common interest of its membership. For future interoperability of production systems and the integration of the production systems with other systems, ODVA embraces the adoption of commercial-off-the-shelf (COTS) and standard, unmodified Internet and Ethernet technologies as a guiding principle wherever possible. This principle is exemplified by EtherNet/IP – the world’s number one industrial Ethernet network.
