2.5.2.1 BACnet MS/TP or BACnet/IP: Assigning Specific Device Instances
With the default Node_Offset value of 50,000 the Device Instances values generated will be
within the range of 50,001 to 50,127.
• The values allowed for a BACnet Device Instance can range from 1 to 4,194,303.
• To assign a specific Device Instance (or range), change the Node_Offset value.
• Methods for changing the Node_Offset value are provided in Chapter 5
o This step cannot be performed until after the unit is connected and powered.
2.5.3 Metasys N2 or Modbus TCP/IP (FPC-N34): Setting the Node-ID
• The Modbus RTU Node-ID’s assigned to the devices attached to the ProtoNode in
Section 2.3.2 will be the Metasy N2 or Modbus TCP/IP Node_ID’s to the field
protocols.
• Metasys N2 and Modbus TCP/IP Node-ID Addressing: Metasys N2 and Modbus
TCP/IP Node-ID’s range from 1-255.
2.5.4 BACnet MS/TP or Modbus RTU (FPC-N34): Setting the Baud Rate for BAS
Network
• “B” bank DIP switches B0 – B3 can be used to set the Field baud rate of the
ProtoNode to match the baud rate required by the Building Management System for
BACnet MS/TP or Modbus RTU.
• The baud rate on ProtoNode for Metasys N2 is set for 9600. “B” bank DIP switches
B0 – B3 are disabled for Metasys N2 on ProtoNode FPC-N34.
• “B” bank DIP switches B0 – B3 are disabled on ProtoNode FPC-N35 (FPC-N35
LonWorks).
