10. UPDATING THE SOFTWARE
The pRack PR100 boards are supplied with the software already loaded. If
an update is required, the following can be used:
• pRack Manager
• SmartKey programming key
10.3 Saving parameters between different
software versions
The configuration parameters can be saved and loaded after having
updated the software. The update requires the files relating to the new
version being loaded (files with the following extensions: .iup, .blx., .blb,
.grt, .dev) and the connection files (files with the following extensions:
.2cf, .2ct, .2cd) for the installed version and the new version.
The connection files must be copied to the ''2cf'' directory under pRack
Manager, for example C:\Program Files\CAREL\pRackManager\2cf.
Note: The pRack PR100 software is protected by digital signature
and cannot be loaded onto hardware other than pRack PR100 (e.g.
pCO3), otherwise after 5 minutes of operation the software locks up, all
the relays open and the warning “INVALID OEM IDENTIFIER” is shown’.
The update files are available at http://ksa.CAREL.com.
The update procedure including saving the parameters is as follows (for
details on the functions of the pRack Manager software see the online
manual):
1. Switch the unit off from the user terminal or supervisor or digital input
2. Connect the PC where pRack Manager is installed using the pLAN serial
(disconnect the terminal if necessary) and disconnect any BMS
connections
3. Start the pRack Manager software
4. In the ''Connection settings'' panel, set Baud rate to ''Auto'' and
SearchDevice to ''Auto (pLAN)'' and select the COM port under
PortNumber (if necessary, use the Wizard to detect the correct COM)
5. In Commissioning/Settings select the .2cf file relating to the version on
pRack PR100, e.g. 1.0
6. Power down pRack PR100, power up again and wait for the controller to
come “On line”
7. In Device Configuration read all the variables and save them to an .txt
file (required)
8. Update the software version on pRack PR100, selecting from pRack Load
the following update files and selecting ''Update graphic resources
and ''Enable zipped upload'':
• .iup (maximum 2 files)
• .blx
• .blb
• ClearAllx.dev, where x is the pLAN address of the board being
updated
9. Wait for the update procedure to end.
10. Power down, disconnect the PC and if necessary reconnect the terminal
11. Power up again and run a quick start-up procedure (pre-configurations
or Wizard, confirming the default parameters)
12. Power down
13. Reconnect pRack Manager and power up again
14. In Commissioning/Settings select the .2cf file relating to the new version
now loaded on pRack
Important: each version of the pRack PR100 software is associated
with a specific controller firmware version (BIOS), therefore if
updating the version, always check and where necessary update the BIOS
on the board. The appropriate BIOS version is supplied together with the
pRack pR100 update files.
10.1 Updating using pRack Manager
The software resident in the pRack PR100 boards can be updated from
a PC.
For the connection procedure see Chapter 9, while for further details see
the pRack Manager program online help..
Note: The pCOLoad program can also be used to update the pRack
PR100 software, however Winload cannot be used.
10.2 Updating using SmartKey
The SMARTKEY programming key can copy the contents of one pRack
PR100 board to another identical board, using the telephone connector
on the terminal (the pLAN must be disconnected).
From a PC, with the SmartKey Programmer software running, the key can
be configured to perform specific operations: acquire log files, program
applications, etc.
The SmartKey Programmer software is installed together with pRack
Manager.
The following figure shows the connection of the SmartKey to the PC
using the PCOSO0AKY0 converter.
,
Important: if using the BMS serial port to read/write variables,
pRack pR100 continues operating, and therefore software
malfunctions may occur. Consequently, use the RS485 serial port
provided for the pLAN connection when carrying out the software
update operations described above.
Note: to update the software without maintaining the parameter
configuration, simply complete steps 1 to 4 and 8 to 10 in the
previous procedure. In this case, the unit will need to be reconfigured
using the complete start-up procedure.
