Using the push button
The push button restarts the pCOnet controller and recalls the factory configuration.
Restarting the pCOnet controller
With the board on and operating normally (status LED flashing continuously), hold the button between five and
10 seconds.
Approximately ten seconds after releasing the button, the Status LED stops flashing. Fifteen seconds later, the
pCOnet restarts and the Status LED quickly flashes red-green-red-green.
Recalling the factory configuration (factory boot switch mode)
The pCOnet card comes with user parameters set to factory configuration values. See “Using the pCOnet
parameters” on page 87 for factory values. In the “factory boot switch¨ mode, pCOnet does not save the
recalled values. When restarted without pressing the button, the pCOnet card again loads the user settings.
The following procedure sets the default pCOnet parameters:
1. Switch the pCOnet controller on with the pCOnet board inserted by pressing and holding the button for
at least 20 seconds. The red status LED flashes slowly three times.
2. After three red flashes on the LED, release the button. The LED turns green. The LED then confirms
recognition of the button by flashing three times red-off, and then returns to green.
Complete start-up of the pCOnet controller takes another 40 seconds and the RS485 LED starts flashing. At
this point, pCOnet controller be accessed via a remote connection.
Additional documentation
Additional documentation relating to the pCOnet BACnetÆË protocol, PICS (Protocol Implementation
Conformance Statement) and the BACset configuration tool are available at http://ksa.carel.com.
Configuring pCOnet parameters
This section provides procedures to configure the pCOnet parameters for correct communication over an MS/
TP network.
1. Connect to pCOnet via a RS485 connection to a computer. During configuration, the Carel product code
CVSTDUMOR0 for USB ports can be used. USB converters should not be used in the installation due to
the large volume of data transmitted across a complex BACnet network
2. Install the Carel “BACset” configuration tool available at http://ksa.carel.com.
N
OTE: If the values of the pCOnet parameters are not suitable, communication with BACset may not be
possible. To connect to pCOnet, restart the pCOnet controller using the “factory boot switch” mode.
Using the pCOnet parameters
The following table and definitions provides details on parameter usage.
Green and red on together (BACnet MS/TP meaning: continuous Poll-For-Master):
communication not established (connection problems, or
no network device found); this may depend on electrical
connection difficulties or communication settings that are
not compatible with the other network devices
connected.
