MODBUS FEATURES

Supported Modbus Functions

The R9120-5 transceiver responds to the following Modbus query functions:
• 0x11 Report slave id
• 0x03 read holding registers (multiple) 0x06 preset single register
These should be sufficient to perform all operations (read many values, make single change, and identify) In addition, the
device will respond to with Modbus exceptions for invalid function, value, and register if out-of-bound requests are made
Modbus function 0x11 Slave ID function will respond with ID=49 "Badger Meter, ModHopper, R9120-5"
