Modbus IP Slave TLM

Introduction

This document describes the intallation, usage, and functionality of a TOPDOC Loadable Module (TLM) for SoftPLC version 4.x and later. The TLM implements the slave (or server) side of the Modbus TCP protocol. As an extention of the standard, it also implements the same protocol on UDP/IP.

It may be used to talk to an MMI Graphical User Interface station or it may be used to talk between other controllers on an ethernet.
