IO-Link PDI to Modbus TCP Master(s) and the Comtrol IO-Link Master

5/26/2015 Page | 2

Introduction

This Applicat ion Note illustrates IO-Link PDI to Modbus TCP Master using:

• Comtrol IO-Link Master (IOLM)

• ifm TD2807 Temperature Transmitter

Your implementation may vary depending on the Modbus TCP Master that you are setting up to operate with the IOLM.

The intent of this is to provide an example that you can use during initial installation of the IOLM.

The IOLM can provide connectivity of Process Data and Service Data from IO-Link sensors and actuators to a Modbus

TCP Client. You can connect more than one Modbus client simultaneously. This connectivity is independent of using of

the EtherNet/IP connections, which may be present on the same gateway at the same time. Clients running

simultaneously do not affect each other when activated or deactivated.

subdirectory. Application Notes are typically protocol-based and function on multiple hardware platforms.

Audience

This Applicat ion Note is intended for system integrators or operators who are responsible for programming or configuring

communications between the IOLM and a Modbus TCP Master.

Prerequisites

If you need procedures for the following, you can refer to the appropriate User Guide or the IO-Link Master Initial

Installation and Configuration Application Note.

• IOLM powered and connected to the network

• IOLM IP address configured

• If necessary, update the IOLM with the

latest images or applications.
