Chapter 16

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. 

This sections provides a brief overview of the steps required to configure the IOLAN for your 
Modbus environment. You can read the 

 sections for more specific information about the Modbus settings.

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

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

Set the serial port that is connected to the serial Modbus Master to the 

 profile.

In the 

 profile on the 

 tab, set the 

 to 

.

Still on the 

 tab, click the 

 button to map the Modbus 

Slave’s IP addresses and their UIDs that the serial Modbus Master will attempt to communicate 
with.

For specialized configuration options, select the 

 tab and configure as required.

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

Set the serial port that is connected to the serial Modbus Slave(s) to the 

 

profile.

In the 

 profile on the 

 tab, set the 

 to 

.

Still on the 

 tab, specify the Modbus Slave UIDs that the TCP Modbus Master will 

attempt to communicate with.

Still on the 

 tab, click the 

 button to configure global Slave 

Gateway settings.

For specialized configuration options, select the 

 tab and configure as required.
