BACnet MS/TP
What you will find in this section:
BACnet MS/TP
BACnet MS/TP operates on a serial RS-485 token-passing network, which is cost-effective for smaller or legacy systems. However, it suffers from slower data rates, limited scalability, minimal security, and more challenging fault diagnosis. Devices in a MS/TP network are only found from superimposed networks, if BACnet routers are installed and configured.
The Empro acts as BACnet MS/TP master. The baud rate and address (between 0 to 127) must be defined to ensure smooth communication within the serial line.
If EMpro is the last device in a serial chain the 120 Ω resistance (integrated to the RS-485 clamps) needs to be activated.
By default BACnet MS/TP communication is deactive. If BACnet IP or Modbus RTU communication is activated, BACnet MS/TP connection gets interrupted.
