SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides expert guidance for configuring and using Apache PLC4X across industrial protocols, simplifying integration with NiFi and cleanly handling connection strings and field addressing.

Core Features & Use Cases

  • Protocol coverage across major industrial standards (S7, Modbus, OPC-UA, EtherNet/IP, KNX, BACnet).
  • Connection string guidance with practical examples and parameter handling.
  • NiFi integration guidance and practical workflow patterns using PLC4X processors.
  • Field addressing and data type mapping references to translate PLC concepts to software.

Quick Start

Use the plc4x skill to outline a basic NiFi flow that reads a Siemens S7 tag via s7://192.168.1.100:102 and a Modbus TCP tag via modbus-tcp://192.168.1.200:502.
