3. COMMISSIONING
The following systems can be used to update and install the Smart HP
application on the pCO controller board:
•
pCO Manager (Winload);
•
SmartKey programming key.
Support files
Following development of the application, 1tool generates various files during
compilation; these include two that are required for commissioning:
<applicationName>.2CF (descriptive of variables)
<applicationName>.2CD (descriptive of categories and access profiles)
3.1 pCO Manager
As well as these files, the <applicationName>.DEV file that contains the predefined set of unit parameters can also be managed.
On all CAREL 16 bit pCO sistema controllers (see the pCO sistema manual) the
resident software can be updated using a PC.
For this purpose, CAREL provides the pCOLoad program and a serial converter
with RS485 output (code CVSTDUTLF0) to be connected to the pCO. The
special driver also needs to be installed on the PC, also provided by CAREL.
The program is included in the installation of the “1Tool” program suite or with
the pCO Manager program, downloadable separately from
http://ksa.CAREL.com, under “download  support  software utilities”.
The installation, as well as the program, also includes the user manual. The pCO
controller can be connected directly to the PC via the RS485 serial port used for
the “pLAN” connection or using the BMS serial port with optional RS485 serial
card used for the “supervisor” connection.
When the commissioning procedure is complete, or for configuration or
monitoring, the user can generate the following files:
<applicationName>.2CW (descriptive of categories, access profiles, monitoring
groups)
<CommissioningLogFileName>.CSV (commissioning log file, containing the data
on the variables recorded during monitoring)
For the configuration phase of the commissioning procedure, the following files
must be available: .2CF, 2CD and where necessary .DEV, which can be imported
and exported.
For the monitoring phase, as well as the files mentioned above, the .2CW file
with the definition of the working environment may be required. The
commissioning log file is an output file only.
Connection modes
Each controller has three serial ports (0, 1 and 2), each with its own default
protocol:
Fig. 3.a
Default protocol
Description
Serial 0
pLAN
Connection to terminal and pLAN network
Serial 1
BMS
Connection to supervisor
Serial 2
FieldBus
Connection to field devices
There are two modes for commencing local communication between pCO
Manager and the controller:
1) Activate the WinLoad protocol on the required port
2) On BMS and FieldBus only, irrespective of the protocol set on the pCO,
simply connect pCO Manager and from “Connection settings” select
SearchDevice = Auto (BMS or FB). In this case it will take around 15-20
seconds to go online.
It must be underlined that updating the BOOT Updating the BOOT is generally
NOT RECOMMENDED by CAREL; during production CAREL always loads the
BOOT required for the correct operation of the unit. Only in very special cases
will CAREL ask the user to update the BOOT.
The BIOS can only be loaded via the pLAN serial connection.
When updating the application and the BIOS, the pCO operating mode switches
to low level. In this special mode, the logged data cannot be downloaded to the
PC nor can the application be loaded in compressed format. To return the unit
to normal communication mode, reset the pCO board.
If uploading the BOOT or BIOS files only, the other application files then need to
be uploaded again.
The consequences of interruption to the upload procedure depend on the
instant this occurs. In any case, the upload needs to be repeated. If pCOLoad
cannot connect to the pCO, a Smart Key must be used to download the BIOS
and any other operating application (e.g.: pCO functional test). This refreshes
the pCO memory, allowing connection to pCOLoad.
Memory limits
The periodical monitoring of the application variables is limited to a maximum
of 250 WORDS, freely selectable from the entire memory available to the
application. The virtualisation of application variables is limited to a maximum of
50 WORDS, selectable from the entire memory available to the application.
There are no address limits for “one-shot” read/write of individual variables: all
memory addresses reserved for the application in all types of memory available
on the pCO can be used: X memory, T memory, P memory, E memory.
3.1.1
Commissioning Tool
Commissioning tool is configuration and real-time monitoring software used to
check the operation of an application installed on a pCO, for commissioning,
debugging and maintenance.
Note: for further details on installing and updating the software on the
pCO controller, see the online help for the pCO Manager program.
This tool can be used to set the configuration parameters, set the values of
volatile and permanent variables, save the trend in the main values of the unit to
a file, manually manage the unit I/Os using a simulation file and monitor/restore
the alarms on the unit where the device is installed.
The configuration functions available on the commissioning tool allow the
designer to decide which variables will be monitored/logged/plotted or
monitored by event, to organise the variables into categories, and to choose the
set of configuration parameters.
