7. UPDATES, FIRMWARE AND LOGS FOR PCO CONTROLLERS

The following systems can be used to update and acquire the firmware and logs to/from the pCO controllers:

•

Winload;

•

SmartKey.

7.1

WINLOAD

In all CAREL 16-bit pCO sistema controllers the resident software can be updated from a PC. To do this, CAREL provides the WinLoad32.exe program and an RS485

serial converter for the pCO. The special driver needs to be installed on the PC, again supplied by CAREL.

WinLoad32.exe is included in the installation of the "Easy Tools" program suite, inside the pCO Manager program or alternatively is available separately at the site

http://ksa.carel.com in the "download : support : software utilities" section.

The installation includes, as well as WinLoad32.exe, the user manual and the driver for the RS232-485 converter. The pCO controller can be connected directly to the

PC via the RS485 serial port used for the "pLAN" connection, or alternatively via the optional BMS serial port used for the "supervisor" connection, with the RS485 serial

board.

The BMS serial port and the optional RS232 serial port can be used to connect the pCO to an analogue (PSTN) or GSM modem and consequently establish a remote

connection to WinLoad32.

Winload can communicate with all the pCO family programmable controllers.

The program is used in general to update and download to the PC the BOOT, BIOS, application, configuration files and logs, and in special cases, such as with the

pCO

, also save files to the new NAND flash.

It should be stressed that updating the BOOT is generally NOT RECOMMENDED by Carel; Carel always loads the BOOT required for the correct operation of the unit

directly during production. Only in very special cases will Carel ask the user to update the BOOT.

The BIOS can only be loaded using the pLAN serial connection. Updating the BIOS changes the unit operating mode to low level. In this mode, the data logs cannot be

downloaded to the PC nor the application loaded in compressed format. To restore the unit to normal communication mode with Winload, reset the pCO after having

successfully loaded the BIOS.

Winload is configured automatically for the unit connected, for example, certain versions of Bios can be loaded or are inhibited, the log configuration may or may not

be available for download, the possibility of the unit to use the expanded RAM is recognised and therefore an application that uses all the RAM available may or may

not be loaded.

In special cases, nonetheless, certain options need to be set, for example, the baud rate if the pCO is a pCO with 14.7 MHz or 16 MHz quartz, using the command line

of a normal Windows connection with the Winload32.exe executable.

The on-line help and the "CHANGELOG" register file in any case provide help to the user.

In general, the sequence of operations for establishing communication between Winload in graphic mode and pCO is as follows:

•

connect the serial converter or USB to the PC and to the pCO;

•

open the Winload program on the PC, by double clicking the icon after having activated any options by command line;

•

on the main screen, set the serial port on the PC that the serial converter is connected to and the pLAN address of the pCO in question;

•

power up the pCO;

•

wait for the controller to come online, as indicated at the bottom left of the main screen;

•

then select the desired directory on the main page to perform the desired operation.

For "EASYWINLOAD" mode, used for automatic loading with the settings made before running the program, and for the remote connection via MODEM, see the

online help in the Winload program.
