The Common Industrial Protocol (CIP) is an industrial protocol for industrial automation applications. It is supported by ODVA.
Previously known as Control and Information Protocol,[1] CIP encompasses a comprehensive suite of messages and services for the collection of manufacturing automation applications – control, safety, synchronization, motion, configuration and information. It allows users to integrate these manufacturing applications with enterprise-level Ethernet networks and the Internet. It is supported by hundreds of vendors around the world,[2] and is media-independent. CIP provides a unified communication architecture throughout the manufacturing enterprise. It is used in EtherNet/IP, DeviceNet, CompoNet and ControlNet.
ODVA is the organization that supports network technologies built on the Common Industrial Protocol (CIP). These also currently include application extensions to CIP: CIP Safety, CIP Motion and CIP Sync.

ControlNet is an open industrial network protocol for industrial automation applications, also known as a fieldbus. ControlNet was earlier supported by ControlNet International, but in 2008 support and management of ControlNet was transferred to ODVA, which now manages all protocols in the Common Industrial Protocol family. Features which set ControlNet apart from other fieldbuses include the built-in support for fully redundant cables and the fact that communication on ControlNet can be strictly scheduled and highly deterministic. Due to the unique physical layer, common network sniffers such as Wireshark cannot be used to sniff ControlNet packets. Rockwell Automation provides ControlNet Traffic Analyzer software to sniff and analyze ControlNet packets.
ComfyUI is an open-source, node-based program that allows users to generate images from a series of text prompts. It uses free diffusion models such as Stable Diffusion as the base model for its image capabilities combined with other tools such as ControlNet and LCM low-rank adaptation, with each tool being represented by a node in the program.
ODVA, Inc. (formerly Open DeviceNet Vendors Association, Inc.) was founded in 1995 and is a global trade and standard development organization whose members are suppliers of devices for industrial automation applications. To qualify for membership in ODVA, applicants must be an entity that makes and sells products using ODVA technologies. ODVA technologies include the Common Industrial Protocol or "CIP" - ODVA's media-independent, object-oriented protocol - along with ODVA's network adaptations of CIP - EtherNet/IP, DeviceNet, ControlNet, and CompoNet. ODVA has more than 15 technical working groups, overseen by its Technical Review Board, which develop and enhance ODVA's implementation specifications for its technologies. These specifications define how a product shall be designed in accordance with the specifications. ODVA maintains a conformance testing practice to validate that products designed using ODVA technologies comply with the specifications and interoperate in multivendor systems. ODVA also provides other services to its members to promote the adoption of ODVA technologies by industry. ODVA is a US 501(c)6 corporation incorporated in the state of Wisconsin. Its headquarters are in Ann Arbor, Michigan U.S. It also has conformance test service providers in North America, China, Germany, and Japan.

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
