4.4.3 CONFIGURING A SLAVE ADDRESS
The 7828 factory configuration sets the slave address to 1. However, in many
applications it will be necessary to allocate another address. In a multi-drop application,
where several Modbus devices are connected on the same network, it is essential to
configure unique slave addresses for each device.
To do this, you will need to run ADView and use the Register Read/Write facility, detailed
in section 4.4.7. Check the value in Register 30 (Modbus Slave Address). If it is not the
required value, enter the desired value and click on the write button. The 7828 will now be
configured with the new slave address.
