AS-I consortium
"[ AS-I ] is a low-cost electromechanical connection system designed to operate over a two-wire cable carrying data and power [...] It is especially suitable for lower levels of plant automation where simple - often binary - field devices such as switches need to interoperate in a stand-alone local area automation network controlled by PLC or PC. At its simplest, AS-Interface is a digital replacement for traditional cable architectures. [...]"
"The AS-Interface association groups users and manufacturers of equipments for the AS-I system.
The task of the user group consists to promote interfaces for sensors and actuators relevant with the AS-I bus."
The most frequently asked question about AS-I, its main features, its installation and how it works.
Design, implementation, wiring, topologies and architectures.
Introduction to the system and fundamentals, basic technology of AS-Interface,slaves and masters AS-I devices, implementation etc ...
The official site
"DeviceNet is a digital, multi-drop network that connects and serves as a communication network between industrial controllers and I/O devices. Each device and/or controller is a node on the network. [...]"

"ODVA is an international association of the most important manufacturers in automation and control solutions.
ODVA and its members support the Common Industrial Protocol (CIP) based networks technologies, which include DeviceNet, EthernetIP, CompoNet and its most important extensions : CIPsafety, CIPsync, and CIPmotion.
ODVA manages the development of these opened technologies, and assists the users and the manufacturers of the CIP based networks providing tools, training and marketing tools."
Interbus official site
"INTERBUS has been designed as fast sensor / actuator bus for transmitting process data in industrial environments. Due to its transmission procedure and its ring topology, INTERBUS offers excellent features like fast, cyclical and time-equidistant transmission of process data, optimal diagnostics to minimize stop periods, easy handling and installation (plug & play) as well as the optimal prerequisites for the use of optic fiber technology."
"INTERBUS is an open systems approach to a high performance, ring-based, distributed device network for manufacturing and process control. INTERBUS is a high-efficiency protocol designed for today's high-speed control requirements. [...] INTERBUS is supported by over 300 third-party I/O device manufacturers worldwide."
"The INTERBUS Club is a worldwide operating organisation. The target is to promote the distribution and positioning of automation technology, in particular INTERBUS, in cooperation with its members."
"The INTERBUS Club furthers the cooperation between its members, supports the further development of up-to-date issues, organises forums and workshops. Its task is to promote the further development and integration of technology, solutions and services.
The association provides a whole of informations about Interbus technologies and about Interbus safety technologies.

IO-link is a communication interface for the lowest field sensors and actuators.
This overview presents the IO-link technology basics, its main features, its architecture, a short resume about the communication mode and the protocol, how operating basically, and where to fin detailed informations.
Shortly, IO-link is a complement to the well knowed industrial networks, and is especially designed to dialog with smart sensors and actuators, adding dynamic adjustment capabilities, diagnostic functions and more.
P-Net official site | Infoside
"The P-NET Fieldbus has been used for many years, and more than 5000 applications are now in operation worldwide. Applications range from simple installations with a few I/O points, to very large and complex installations using many thousand I/O points.
P-NET applications are found in the process industry environment and in discrete parts manufacturing plants."
"The site of IPUO - the International P-NET User Organization] is for all who is interested in fieldbus systems for process automation, control and data acquisition."
