9. SUPERVISORY AND COMMISSIONING SYSTEMS

pRack PR300T can be connected to various supervisory systems,
specifi cally the Carel and Modbus communication protocols can be used.
For the Carel protocol, the PlantVisor PRO and PlantWatch PRO models
are available. In addition, pRack PR300T can be connected to the pRack
Manager commissioning software.
9.1 PlantVisor PRO and PlantWatch PRO
supervisory systems
Connection to Carel PlantVisor PRO and PlantWatch PRO supervisor
systems uses the RS485 card already fi tted on some models of pRack
PR300T. For details on the models of card available, see Chapter 1.
Note: In general, the pRack boards that manage the suction lines
must be fi tted with the supervisor connection card, consequently
boards with pLAN address 1 or 2.
Three diff erent models of PlantVisor PRO and PlantWatch PRO are
available, used to supervise system confi gurations with one or two lines:
•
L1 – one line: can be used for system confi gurations with just one
suction and/or condenser line.
•
L2 – one line: can be used for system confi gurations with two suction
and/or condenser lines, and the two suction lines are managed by
separate boards.
•
Two lines: can be used for system confi gurations with two suction and/
or condenser lines, and the two suction lines are managed by the same
board.
Important: model L2 – One line must be used only in association
with model L1 – One line. For supervision of system confi gurations
with just one line only model L1 – One line can be used.
Tutorial: the rule applied for using the models is summarised
below:
•
cconfi guration with board with pLAN address 2
•
confi guration without board with pLAN address 2
A connection example for using PlantVisor PRO and PlantWatch PRO is
shown in the fi gure.

9.2 Commissioning software

pRack Manager is confi guration and real-time monitoring software used
to check the operation of pRack PR300T, for commissioning, debug and
maintenance operations.
The software is available on the internet at http://ksa.CAREL.com in the
section "download à support à software utilities".The installation includes,
in addition to the program, the user manual and the necessary drivers.
pRack Manager can be used to set the confi guration parameters, modify
the values of volatile and permanent variables, save graphs of the main
system values to fi le, manually manage the unit I/Os using simulation fi les
and monitor/reset alarms on the unit where the device is installed.
pRack PR300T is able to virtualise all the inputs and outputs, both digital
and analogue, therefore each input and output can be overridden by
pRack Manager.
pRack Manager manages <fi le name>.DEV fi les that contain the user
parameter confi gurations and that can be downloaded from the pRack
PR300T board and then subsequently uploaded.
To use the pRack Manager program, a serial converter output RS485 with
CVSTDUTLF0 (telephone connector) or CVSTDUMOR0 (3 pin terminal)
must be connected to the board.
The connection to pRack Manager can be made:
1.
Via the RS485 serial port used for the "pLAN" connection
2. Via the BMS serial port with RS485 serial card and activating
the pRack Manager protocol by parameter on screen Fca01 or
connecting pRack Manager and selecting SearchDevice = Auto (BMS
or FB) on the "Connection settings" tab. In this case, the connection is
established after around 15-20 seconds.
Important: the BMS serial port should only be used for monitoring
the variables, while to update the software use the RS485 serial
port dedicated to the pLAN connection.
The following fi gure shows an example of connection to the PC via the
RS485 serial port used for the "pLAN" connection
