May 2014 - It is a pleasant feeling when your audience agrees with you. Recently at the Tridium Conference, Contemporary Controls was presenting "5 ways to Enhance your JACE". One of the primary ways to enhance the JACE was to offload the BACnet MS/TP traffic from the JACE. Instead of using an MS/TP driver in the JACE a BACnet/IP client driver was installed in the JACE and a Contemporary Controls BASrouter was used as the interface to the MS/TP devices. Let's take a look at what we discovered.
The test setup included:
With the JACE utilizing an MS/TP driver the CPU load was between 40% to 80%.
With the JACE communicating to the MS/TP points via BACnet/IP through the BASrouter the CPU load was 20% to 40%.
More JACE CPU time is available for performing other activities in the JACE when using the BASrouter solution.
Other concepts to consider.
We received many positive comments about our presentation for "offloading the JACE". For more information, visit enhanceyourjace.com.
