Modbus Slave Settings

When you have Modbus Slaves on the serial side of the IOLAN, configure the serial port to the Modbus Gateway profile acting as a Modbus Slave. There is only one Slave Gateway in the IOLAN, so all Modbus serial Slaves must be configured uniquely for that one Slave Gateway; all serial Modbus Slaves must have unique UIDs, even if they reside on different serial ports, because they all must be configured to communicate through the one Slave Gateway.

Modbus Master

Slave Gateway

TCP Network

IOLAN

IP: 10.10.10.10

Serial Port 1

EIA-422/485

Modbus Master	Modbus Slave
Modbus Master	Modbus Slave	UID: 7
	UID: 6	Modbus Slave
		UID: 8

To configure the Modbus Gateway on serial port 1, do the following:

1.Select the Modbus Gateway profile for serial port 1.

2.On the General tab, enable the Modbus Slave parameter.

3.Still on the General tab, specify the UID Range as 6-8as shown below:

4.Click the Advanced Slave Settings button to verify that the default settings are acceptable.
