To change the address of Device you can use the script function as below:

Con_SlaveEquipmentAddress example:

int [ ] slaveAddress = {10.EN_US};

ModbusEquipment01.openConfig();

ModbusEquipment01.setProperty( "Con_SlaveEquipmentAddress", slaveAddress );

ModbusEquipment01.commitConfig();

As per the above example you need to first use Openconfig function where ModbusEquipment01 is the name of the equipment.

You can use setProperty function to set the property and Con_SlaveEquipmentAddress is the property of address.

After setting the property you need to call function commitConfig to save the configuration.

In the above example slaveAddress is a int variable which has been set to the value 10 to set the slave ID 10 for that particular equipment.
