BACnet 802.3 Master

08 May 2026

PROTOCOL IMPLEMENTATION CONFORMANCE STATEMENT 

 

APPLICABLE PRODUCTS

  • All Products Using Crimson 2.0 or Crimson 3.0 BACnet Slave Drivers 
  • G3 Series of HMI
  • Data Station Plus Series and Modular Controller Series 

 

PRE-REQUISITES 

  • Crimson 2.0 Build 2.0.0.324 and Later
  • All Builds of Crimson 3.0 and up 
  • BACnet Version 1, Revision 5 

 

IN THIS ARTICLE 

The products are advanced data-management devices that perform protocol conversion and data logging, and also provide a web-based virtual HMI facility. The G3 HMI products combine this functionality with color touchscreens for local viewing. The products support BACnet slave and master modes, over MS/TP, 802.3 and UDP/IP. 

*While BACnet is a peer-to-peer protocol, the Red Lion Controls implementation configures as a Master (client) or Slave (server).
