The meter’s Factory module stores meter details such as device type, serial number, and vendor
name. You can use ION Setup in advanced mode to view the contents of the Factory module’s
setup registers. Similarly, you can use Modbus commands to read the Modbus registers mapped
to the corresponding Factory module’s registers.
NOTE: Not all ION device setup registers are mapped to Modbus registers by default.
Other device-specific details, such as Product Code, are not stored in the Factory module.
Product Code (also known as Modbus Product ID) is a number that the manufacturer assigned to
a product to uniquely identify it, for use by systems that specifically require this information. You
can use the device’s Modbus map and Modbus commands to read the Modbus Product ID.
