Introduction

This chapter provides examples of how to integrate the IOLAN within different network environments or applications. Each scenario provides an example of a typical setup and describes the configuration steps to achieve the IOLAN functionality feature.

Configuring Modbus

This sections provides a brief overview of the steps required to configure the IOLAN for your Modbus environment. You can read the Modbus Gateway Settings on page 322 and Modbus Serial Port Settings on page 323 sections for more specific information about the Modbus settings.

Overview

This section describes the high-level steps required to configure the IOLAN as a Modbus Master or Slave Gateway.

Configuring a Master Gateway

To configure a Master Gateway (Modbus Master connected to the serial side of the IOLAN), do the following:

1.Set the serial port that is connected to the serial Modbus Master to the Modbus Gateway profile.

2.In the Modbus Gateway profile on the General tab, set the Mode to Modbus Master.

3.Still on the General tab, click the Destination Slave IP Mappings button to map the Modbus Slave’s IP addresses and their UIDs that the serial Modbus Master will attempt to communicate with.

4.For specialized configuration options, select the Advanced tab and configure as required.

Configuring a Slave Gateway

To configure a Slave Gateway (Modbus Master resides on the TCP/Ethernet network), do the following:

1.Set the serial port that is connected to the serial Modbus Slave(s) to the Modbus Gateway profile.

2.In the Modbus Gateway profile on the General tab, set the Mode to Modbus Slave.

3.Still on the General tab, specify the Modbus Slave UIDs that the TCP Modbus Master will attempt to communicate with.

4.Still on the General tab, click the Advanced Slave Settings button to configure global Slave Gateway settings.

5.For specialized configuration options, select the Advanced tab and configure as required.
