Viconics VWZS Integration Guide - Manual (Page 29)

Device Info, Address Info & Communication Module Info: All read only properties related
to the local controller and are given as general information.
Wireless Signal Info:
CRSS - Coordinator Receiving Signal Strength (in %)
TRSS - Controller Receiving Signal Strength (in %)
These values can be known before implementing the Viconics wireless system by using the
Viconics Survey Tool (VST5000W5000W). It will determine if the area is suitable for using
Viconics wireless products. Any value from 10 to 100% indicates good ZigBee connectivity.
Any
value below 10% “may” indicate that an extra Router VRP 5000W1000W may need to be
installed.
Controller Objects Supported
Please note that the wireless objects related to any specific controller exchange present value
to and from the JACE on a fixed COV subscription base.
Back and forth from the JACE to the wireless controllers, the COV values are fixed to:

2.5% for PI demand Numeric objects

0.5 for all temperature ( C & F ) and humidity Numeric objects
 On change for all Enum’s & Boolean’s
A “recommended” typical maximum of:

30 network able controllers can be supported by a single JACE2.

50 network able controllers can be supported by a single JACE6.
The total number of controller supported is also dependent on the resources available for the
“WirelessTstatNetwork” driver Jar file and the extent of integration added to the JACE
station itself.
