If the controller is communicating properly with the building automation system, both numbers will continue

increasing in value. For Modbus protocol, the read and write numbers should be equal and increasing with every

poll. For BACnet, both numbers should be increasing, but they will not be equal. The write value will increase

even when not connected.
For the JC Metasys N2 protocol, both numbers should be increasing but may not be equal. If both numbers are

not increasing in value, the controller is not communicating properly. Check the wiring at the terminal blocks. See
