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).
