ProfiBus
PROFIBUS is an industrial communication protocol that has been widely used in automation systems since its development in the late 1980s. It is a fieldbus communication system used to connect various industrial devices such as sensors, actuators, drives, and programmable logic controllers (PLCs) to a central controller.
PROFIBUS uses a master-slave architecture, in which a single master device controls and communicates with multiple slave devices. The master device controls the communication process by sending polling messages to the slave devices, which respond with data. PROFIBUS supports both cyclic and acyclic communication, which allows for real-time data exchange and on-demand data transfer as needed.
One of the key advantages of PROFIBUS is its flexibility and adaptability to different industrial applications. It can be used in a wide range of industries, including automotive, food and beverage, chemical, and pharmaceuticals. Additionally, it offers a high level of reliability and fault tolerance, enabling efficient communication even in harsh and noisy industrial environments.
Overall, PROFIBUS is a widely used and well-established industrial communication protocol that has proven to be reliable, flexible, and efficient in connecting various devices in automation systems. However, it is important to note that newer communication protocols such as PROFINET have been developed to offer greater performance and functionality in modern industrial applications.
DeviceNet
DeviceNet is a communication network protocol used in industrial automation systems. It is a part of the family of networks known as the Common Industrial Protocol (CIP) developed by the Open DeviceNet Vendors Association (ODVA).
DeviceNet uses a multi-drop network topology, meaning that multiple devices can be connected to the same network or "trunk" using a single cable. This allows for simplified wiring and reduces the cost of installation and maintenance.
One of the main advantages of DeviceNet is its ability to provide real-time data exchange between devices, enabling high-speed communication and control within an automation system. This is especially important in applications where timing and precision are critical, such as in motion control, robotics, and assembly line production.
DeviceNet uses the Controller Area Network (CAN) protocol for communication, which is a message-based protocol that enables devices to communicate directly with each other without the need for a central computer or controller. This makes it a highly flexible and efficient communication protocol for industrial automation.
DeviceNet also supports plug-and-play installation of devices, making it easy to add or remove devices from the network as needed. It also provides diagnostic and monitoring capabilities, allowing for easy maintenance and troubleshooting of the network and connected devices.
Overall, DeviceNet is a widely used and reliable communication protocol for industrial automation systems, providing high-speed communication, real-time data exchange, and simplified wiring and installation.
CC Link - Control & Communication Link
CC-Link is a popular open-architecture industrial communication network that provides high-speed, deterministic communication between devices in an automation system. It was developed by the Mitsubishi Electric Corporation and is widely used in various industries, including automotive, food and beverage, and pharmaceuticals.
CC-Link is designed to support both cyclic and acyclic communication, providing real-time data exchange and on-demand data transfer as needed. It is a scalable and flexible network that allows for easy integration of new devices and expansion of the network.

RelayUnit
The relay unit is an I/O module (input/output module) and connects binary sensors and actuators with the robot controller. It is used to evaluate sensor signals and to control actuators, e.g. valves.
The I/O communication that can be realised with a relay unit is the simplest form of connecting the robot controller with the periphery.
It is inexpensive and not susceptible to faults but requires a not inconsiderable amount of wiring.
This type of communication has no protocol and no independent detection or correction of transmission errors.
Troubleshooting can also be relatively time-consuming.
A relay unit is limited to a maximum of 32 inputs and 32 outputs.
A maximum of 3 relay units can be installed in a robot controller.
