• BACnet® MS/TP on Saia PCD®

    PCD2.F2150 and PCD3.F215

Introduction

The communication modules PCD2.F2150 and PCD3.F215 with BACnet MS/TP allow the direct connection of max. two BACnet MS/TP lines and can be plugged on a PCD1.M2, PCD2.M5 or PCD3.

 

Furthermore these modules are equipped with an RS485 interface and one slot for PCD7.F1xx cards. They are fully compatible with SBC Mode-C and S-Bus communication, so all the usual serial protocols and F-Boxes for F2xx interfaces are supported.

You will always need an BACnet card PCDx.R56x to work with BACnet MS/TP.

 

Module overview

There exist 2 different  module types to be plugged into PCD I/O slot 0..3.

Good to know

  • There is an example of a PG5 project for BACnet MS/TP communication available in the Getting Started area.
  • The BACnet MS/TP option is supported from PG5 2.1.100.
  • The PCD needs firmware version of 1.20.25 or more recent.
  • The usual instructions for RS485 installation must be followed.
  • The BACnet Network nr. must be unique. Do not use double network numbers or the local network (0). In case you have BACnet IP and MS/TP networks connected to the same PCD use different network numbers for the two networks.
  • Baudrate must be the same for all devices, BACnet MS/TP does not demand autobauding!
  • Amount Master per Network max. 126 + the modul itself
  • Take care about the BACnet Networklayer configuration. Details you can fnd in the Online Help of the BACnet Configurators.
  • Telegram lenght for MS/TP is limited to max. 480 Byte.
  • When extending existing BACnet projects with BACnet MS/TP, the data link settings must be transferred from the Saia BACnet Configurator to the Saia Device Configurator. The BACnet data link settings of the Device Configurator have priority!
