A VT Win project which had a size of a few MBytes becomes after storing more then ten time bigger (100-200MBytes).

Problem
The size of the project increase after storing to a really hughe size.

Reason
If unicode fonts are used which are not present in the PC the project can become so big because each character has to be stored as bitmap.

Solution
Check the fonts you are using and change to a font which is installed on the PC.

This is possible if following rules are respected:

• Both Terminals must be of same type
• PCD8.D80E SW must be as old as Revision-Version of terminals or more recent.

Recent versions of Windows OS do not allow the access to COM-ports in the way which is used for DOS.

Use an operating system which is based on DOS (DOS, WIN 3.11, Windows 95 or Windows 98) instead.

PCD7.D8 is a DOS-program which access directly the COM-Ports of PC. Windows NT, 2000, ME and XP does not allow such accesses and therefore it's not possible to download anything to terminal from a PC which is running on one of those Operating systems

• Power on the terminal keeping pressed the ENTER key until you read on the display the text " wait for boot forced ".
• If you aren't able to see this text, you can power off/on the terminal quickly, without never release the ENTER key.
• When the message appears on the screen, you can release the ENTER key and download the right firmware
• Choose the item " TX  FW / DRIVER ", e.g. SBC. ( it must be the right for the project you need to load in the VT )
• After the FW downloading, you can download the project

Before a firmware or application download is possible, the PCD7.D8xx terminals must be put in download mode.

Procede as follows:

• remove the power supply

• press enter and keep it pressed

• apply the power supply

The display has a frozen screen (can be black if in standby mode) and can't be operated. After a powerup the project's start page is displayed but the touch screen doesn't respond, because the calibration has been lost!

Solution
The firmware (PCD7.D761) needs to be updated! The firmware update is done when downloading the project to the panel when the option "Update operating unit firmware" is activated.
If the display can't be forced in transfer mode (download mode) it might be necessary first to recalibrate it as explain in FAQ 100868 (see link below).
Use the latest PCD8.D81W 5.18 version which contains the newest FW!
If you haven't le possibility to use this version and you have the version 5.12 you can also add the new Fw in attachment. So, please execute the following steps:

• Download the files attached to this FAQ and unzip the archives.
• Copy the firmware files "VT155W.BIN" into the following folder:
  "C:\Program Files\SAIA\PCD8.D81W_512\\firmware\"
• Open the VTWIN project, compile it again and download it to the panel and active the download option "Update operating unit firmware".
• When the download has finished, after a powerup of the panel, please verify that the new firmware version is: 1.13.

New: Use the actual programming tool version PCD8.D81W V 5.18 which contains already the new firmware version. So no need to copy the fw files in attachment!

On a Profi S-Bus network when PCD7.D76_ terminals are connected to PCD3.Mxxx or PCD2.M480 PLC's over Profi S-Bus, the terminal loses the communication after some time and get even frozen. This problem is corrected in the new boot, FW and driver. The PCD8.D81 V 5.09 is needed , the attached files have to be copied in it (see procedure below).

It is also necessary to update the PCD3.Mxxx and PCD2.M480 FW with the version PCD3.Mxxx_023.blk / PCD2.M480_$27 or newer! Ask the PCD technical support or your representation for it!

Attached you can find the new boots, firmwares and driver that resolve the problem with the Profi-S-Bus network.
The booter file " BT155MTF" and BT525MTF have to be copied in the following folder
C:\Program Files\SAIA\PCD8.D81W 5.09\Boot

NEWS: In the latest version PCD8.D81W V 5.12 contains all thoses updated FWs, drivers and boots! Ask the technical support or your representation for it!

It is possible to convert all the variable from a S-Bus driver to Ether S-Bus driver if an existing project has to be used on another terminal type (e.g. PCD7.D786 convert to PCD7.D786ET)!

Hereby the procedure to convert your project from VT585W (PCD7.D786) rev 4 to VT585WB ETH  (PCD7.D786ET) in order to save the addresses of the project variable when you change the driver from SBC S-bus to SBC Ethernet S-bus:

Since the version V5.07, it is possible to import the global symbols from a Saia PG5® project. Because the online help doesn't explain the import procedure correctly, you can find a corrected version attached to this FAQ!

If you need an update of your VTWIN version to this beta version, please contact your local Saia-Burgess Controls AG representative.
The beta version 5.09 is now available!

If you would like to insert special characters like "é", "ö", "@", etc. in field "Multilanguage label" just press "F12" and a character table will apear.
