User Interface Card - ProFire PF2200-SB Product Manual

2.1.1 USER INTERFACE CARD

The User Interface Card allows interaction with the system through the use of the keypad and a display.
This card interacts with the BMS card through a proprietary communication protocol, called PFN, which
utilizes the RS-485 physical transport layer. PFN and power to the User Interface are factory wired to
the BMS card through a wiring harness.
2.1.1.1 MODBUS
Remote access to status information and non-safety critical settings can be achieved via the Modbus
port of the User Interface card. The Modbus port supports Modbus RTU over the RS-485 physical layer.
For a complete register list, see PF2200 Single Burner BMS – Modbus Registers. By design, safety critical
settings are not accessible via Modbus.
2.1.1.2 USB
The USB port of the User Interface Card has two main uses: data-logging and updating firmware. Data-
logging is enabled by going to the Firmware Update screen on the User Interface and is limited by the
size of USB stick-- a USB stick of size 1GB or larger is recommended. Firmware update is only
supported using authorized firmware bundles. Contact Profire Energy for an authorized firmware
bundle.
