This document serves as a quick reference guide for various protocols utilized in industrial control systems and operational technology. It categorizes protocols into three main groups: common protocols, vendor-specific protocols, and database protocols.
Common Protocols
The common protocols listed include:
- IEC 60870: A standard for telecontrol equipment and systems.
- IEC 61850: A standard for communication networks and systems in substations.
- OPC: A series of standards for interoperability in industrial automation.
- ModbusTCP: A widely used protocol for communication in industrial devices.
- MQTT: A lightweight messaging protocol for small sensors and mobile devices.
Vendor-Specific Protocols
The document also highlights specific protocols developed by certain manufacturers:
- ADS (Beckhoff): A protocol for communication with Beckhoff devices.
- CC-Link IE (Mitsubishi): A high-speed network protocol for automation.
- CIP (Rockwell): Common Industrial Protocol used in Rockwell automation products.
Database Protocols
For database management, the document mentions:
- Microsoft SQL
- Oracle
- MySQL These protocols facilitate data storage and retrieval in industrial applications.
IT Protocols
Additionally, it covers essential IT protocols such as:
- DHCP: For dynamic IP address allocation.
- DNS: For domain name resolution.
- FTP: For file transfer.
- HTTP: For web communication.
- SNMP: For network management.
Port Assignments
Each protocol is associated with specific ports, which are crucial for network communication. For example, TCP port 135 is designated for OPC, while TCP port 502 is used for Modbus.
Overall, this document provides a comprehensive overview of the protocols that are fundamental to the functioning of industrial control systems, ensuring interoperability and efficient communication across various devices and platforms.
