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).
