ABB AC500 Remote Access via Router Port Mapping Guide

About this manual

This technical document provides instructions for customers to achieve remote access to multiple ABB AC500 series PLCs. It details the process of using router port mapping (port forwarding) to allow remote login for programming and remote Modbus-TCP communication, where the PLC acts as a Modbus-TCP server.

The guide covers system configuration, including setting up the PLC Ethernet ports, configuring the TP-LINK TL-WDR3310 router (WAN/LAN settings, static IP allocation, and virtual server rules), and establishing connections. It includes specific steps for remote login using Control Builder Plus and Modbus-TCP client software like ModScan32. This manual is written in Chinese.
