Auto Discover and Auto Addressing
An improved commissioning workflow has been designed for all BACnet PTEC
controllers (standard 66
xx
applications) along with WCIS (Revision 4.0 and later). This
provides the option to use the MS/TP network (using the field panel or a router) and
the WCIS tool to discover and auto-address each controller. For more information, see
the
WCIS Online Help
.
NOTE:
The current workflow will continue to support setting the baud rate and address for
each controller using the HMI port or at the room unit.
All BACnet PTEC controllers (standard 66
xx
applications) have an internal unique
serial number and a two part serial number label.
1. Connect WCIS to the field panel or use a router connected to the MS/TP network.
2. Assign one PTEC a valid address (using the serial number). This will establish and
set the baud rate for the entire network.
Auto Discovery allows you to automatically discover and identify PTEC/ATEC
controllers on the BACnet MS/TP Network. There are two basic configurations:
Devices not configured with an address. (Devices are discovered by their unique
serial number.)
Devices configured with an address and available for modification.
Filtering
These buttons allow you to select what you see in the Auto-discovery window. All three
buttons are selected by default.
Unaddressed - Displays unaddressed devices
Failed - Displays failed devices
