Quickstart Guide
ABB PLC and drives integration using Modbus RTU
Introduction
This guide will take you through the hardware installation and configuration of ABB ACS Drives and PLC in order to
prepare for Modbus RTU control. ABB‐specific ready‐made function blocks and visualizations from the PS553‐
DRIVES library will be used for the control of the drives. While the guide is applicable to all AC500 PLCs and all
Modbus RTU compatible ABB ACS drives, the example is built up with an AC500‐eCo PLC and an ACS355 drive.
Note! The material in this application might need to be adapted according to actual equipment and function
before it is used. Testing of the equipment must always be performed by the responsible start‐up person according
to current legislation before the equipment is placed in service. ABB does not take any responsibility for possible
damage caused by using the material in this application (shown examples, data, project tools, etc.).
Safety instructions
Follow all safety instructions delivered with the used components:

Read the complete safety instructions for the used drive before you install, commission or use the drive.
The complete safety instructions are given at the beginning of the drives user's manual (e.g. for ACS355:
3AUA0000066143 [English]).

Read all safety and installation instructions of the used PLC. See the online help in CoDeSys (Help →
Contents → Target System → AC500 / S500 → Introduction → Overview → Regulations).
