Industrial Communications
Communication protocols and standards in automation: OPC, MQTT, REST API, Modbus, PROFINET and more.
Industrial communications are the backbone of any modern automation system. From classic protocols like OPC DA and Modbus to the latest such as OPC UA, MQTT, and REST API interfaces, in this section we bring together articles on configuration, integration, and best practices for the main standards.
OPC DA and OPC UA standards: KEPServer, RSLinx, Simatic Net, OFS, DAServer, TwinCAT OPC configuration and more.

Modbus is one of the most established and widely used protocols in industrial automation. Available in serial (RTU/ASCII) and Ethernet (TCP) variants, it remains essential for communication with PLCs, drives, and field devices.
SNMP — Simple Network Management Protocol
SNMP enables monitoring and managing network devices (switches, routers, industrial gateways) from monitoring systems.
