Changing the Modbus Address
Overview
Each port can be assigned a Modbus network address in the range 1 ... 247. That
address must be unique with respect to all other device addresses on the same
Modbus networks.
Since Modbus port 1 and Modbus port 2 are always on different Modbus networks,
they can both be assigned the same address value without conflict. The factory-set
default for both ports is address 1.
Procedure
From the Modbus Port Settings dialog box, perform the steps in the following table
to change the Modbus Address:
Step Address
1 Click on the Address field for the appropriate Modbus port.
2 Type a new value in the range 1 ... 247.
