5.
In the
Device Settings
section
(configuring the Room Unit port), do one of the
following:
If using a sensing only Room Unit, the baud rate can be 1200 to 38400.
Use
38400
for optimal use with WCIS.
If using a communicating digital Room Unit, the baud rate uses whatever
rate the network is using or sets it to 19200 after the controller address
is configured.
6.
In the
Device Settings
section:
Set
MMI Baud Rate
to
38400
.
7.
Press the
Write
button. The controller accepts the configuration values and
then resets.
When the BACnet MS/TP TEC is successfully installed, the RX and TX
LEDs continuously flashes On/Off rapidly. This indicates a proper
communication with other devices on the network.
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.
