Technical Informations
OPC DA – OPC Data Access
The process data interpreter
basics
In automation technology, hardware components from a wide variety of manufacturers are usually assembled into a system. In the past, each manufacturer pursued its own way of passing on process data to the software level. This affects both the physical communication path and the data format.
OPC UA – OPC Unified Architecture
OPC support out of the box
MQTT – Message Queue Telemetry Protocol
Data exchange without direct connection
The special feature of MQTT is that two communication partners who exchange data with each other never do so via a direct connection.
REST – REpresentational State Transfer
Industrial communication based on standardized HTTP requests
REST does not describe an actual protocol structure. Rather REST prescribes properties which should be met for data communication in industrial environments.
Modbus TCP
Standard protocol for automation technology
Modbus was originally developed as a serial field bus by Modicon (today Schneider Electric) as a communication path between their controls.
Data Formats And Protocols
From simple bytes to industrial protocols
What is data?
Whether digitalization, Industry 4.0 or IoT (Internet of Things), ultimately it is about the fact that various, often industrial components and their users, exchange data with each other.
