How to install drivers for Systec USB CAN Interface

There is a considerable amount of magic in this procedure, something like this will work with patience. Experts ONLY - you can mess things up !

There are instructions on the CERN IT Division web site


Follow those instructions but use the latest drivers from the systec webpage (see below). The installation windows appeared only eight rather than sixteen times.

Here is a somewhat different version of the installation instructions. These only seem to work temporarily, after a while the system starts complaining about the drivers not being installed. Disconnect the USB CAN connector.

Download drivers from Systec webpage, http://www.systec-electronic.com/html/index.pl/en_downloads_can_interfaces

  1. downloads -> CAN interfaces -> USBCANModul->USB-CANmodul Utility Disk (currently version 4.04 of file SO-387.zip)
  2. downloads -> CAN interfaces ->CAN Ethernet Gateway->CAN Ethernet Gateway Utility Disk (Driver) (currently file SO-1027.exe)
You need both drivers.

Uninstall previous systec USB can drivers, using the control panel -> add/remove programme

Then restart the computer

Install the downloaded drivers.

Then restart the computer again.

Reconnect the USB CAN connector.

Message appears that new hardware has been found.

Instead of using the wizard directly, right click My Computer, select properties, hardware, device manager. click USB-CAN-Hardware.

you should see one installed 'systec USB-CANmodul network driver' and several multi-port USB-CAN (this is unconfigured state).

Right click on one multi-port USB-CAN, select properties, driver, select update driver and thw wizard appears. select install software automatically, click next to install. After installation this changes to 'systec USB-CANmodul network driver' , so you now have two.

You can remove the remaining multi-port USB-CAN

You can use control panel -> USB-CANmodul control to connect the USB port to a network driver. You will see two entries in this. they should both show net in the final column. If not you can try selecting the device and select change. click usb-CANnetwork driver.

How to use the standalone ISEG HV control

Experts ONLY - normal users do not need this and should not use this.

First stop WinCC client DA8 in VEDCSHV project. You cannot use both ISEG HV control and WinCC client simultaneously.


This should say 'isegCANHVControl has been connected to SYS TEC USB-CAN ! Bus status:OK'

If you have been using a different CAN interace (e.g. peak) you need to go to the 2nd icon along which is for the 'CAN hardware setup'. Select systec USB CAN and save and press OK.

The list on the screen gives each board that is connected (each module has two boards). Clicking on a board opens another panel from which voltages can be set.

How to configure the OPC server

Experts ONLY - normal users do not need this and should not do this.

If you are changing interface type (e.g. peak to systec) change the name of the dll in case this is picked up by accident.

e.g. change C:\WINDOWS\system32\isegpcan.dll (this is the peak one) to isegpcan.dll_old

the systec dll is called isegscan.dll

run isegHVOPCConfiguration (C:\Program Files\iseg\OPC\isegHVOPCConfiguration->iseghvopccfg). There should be a short cut to this on vecc0103w from the Programs menu

go to CAN hardware setup (2nd icon) and select systec USB can. save and press OK.

edit ini file (1st icon) and select systec USB can. save and press OK. make sure the two configuration files have ticks by the side of them.

now select ECH crates. click configuration. new window appears. click on the Scan 'S'. the crate ID appears on the right hand column. click ID to order them by ID number (if more than one).

click add all to put in the left hand column. use the file menu to save, with the suggested file name replacing prev. file.

click remove all to leave the left hand column blank.

repeat this process for configuring the modules.

How to configure the WinCC OPC client (the list of can bus, crates, modules, channels)

Experts ONLY - normal users do not need this and should not do this.

open device editor and navigator.

click hardware tab

click iseg + to show can0

go to editor mode

right click can0. remove. so now all previous tree is removed.

right click can0. add. click OK.

now crate00 should appear under can0.

on crate00 click add. do create many. enter under the changing box numbers e.g. 00 to 11 will create for six modules. tick also create children. click OK.

the full tree should now be created.

How do I know which version of the OPC server I'm running ?

Experts ONLY - normal users do not need to know this.

device editor and navigator.

hardware tab

navigator mode.

click can0.

How do I install a new framework component ?

Experts ONLY - normal users should not do this.

From device editor and navigator, hardware tab, editor mode.

right click on VEDCSHV, select installation tool

(An alternative way of getting this is

From WinCC console, start User Interface -m gedi.

click on the vision icon ( cog with arrow, five along).

open: (pit) G:\online\ecs\PVSSShortcutProjects311\GlobalProject\panels\fwInstallation\fwInstallation.pnl (lab8) L:\pvss\VEDCSHV\panels\fwInstallation\fwInstallation.pnl

don't set up a link to the fw...DB

choose fwISEG, and select delete

use installation tool on left hand column. browse to find new component. click in install box, then install.

In addition you may need to migration panel, if the device classes change.

Again, From PVSS console, start User Interface -m gedi.

click on the vision icon ( cog with arrow, five along).

open (pit) G:\velo\pvss\fwComponents_VEDCSHV\panels\fwIseg\fwisegMigration.pnl (lab8) G:\velo\pvss\PvssDevelopmentComponents\fwComponents_VEDCSHV\panels\fwIseg\fwisegMigration.pnl

select devices to upgrade and method of migration (e.g. 8 channels rather than 16), then click

How do I change from EHQ to EHS mode of modules ?

Experts ONLY - normal users should not do this.

EHS with class 25 is the recommended operation mode.

close WinCC OPC DA client 8. (cannot do simultaneously with PVSS running)

open isegHVConfiguration

choose multi-channel modules and click on configuration

scan with S icon

click on padlock, the password is Config

a chip icon appears, click on this.

click required mode EHS or EHQ

the modules in the scan list have two digits after their number which show the device class, for example 0552 25, means device class 25 which is EHS. The digits for device class 07 correspond to EHQ.

How do I upgrade the firmware in the ISEG HV module ?

Experts ONLY - normal users should not do this.

NB: This procedure only works with the PEAK interface at the moment. Problem reported to ISEG with a request to fix the problem for the SysTec interface.

You can find the readme file about the Iseg firmwares to be used following this path :

C:\Program Files\iseg\OPC\isegHVOPCServer

The firmwares files are located following this path :

C:\Program Files\iseg\isegCANHVControl\HEX

The best way to update the HV modules with this older firmware releases is:

  1. Switch all modules together in a carte to EHS mode
  2. Perform a single update for each HV board with only one module in the crate
  3. Start isegCANHVControl (r 1.57)
  4. Click on the board to be upgraded to open the board-specific window.
  5. Click on the padlock and input the password hex2flash
  6. Click on the chip-icon that appears in the tool bar to open the update dialog.
  7. Brows to open the hex file (for instance e08f0_226.hex)
  8. Push the button "flash programming"
  9. A progress bar is running during the update. At the end of the update the LED on the front panel will blink three times, wait until the button "close" will be visible on the dialog. It should show the word 'Fiinished' in the status bar.
  10. Close the update dialog
  11. When update process has been made without failures switch to the second HV board and repeat the steps above from point 6 to 10.
When the update process has been stopped an the module is not accessible there is a possibility to repeat the update process by following steps:

  1. Close isegCANHVControl
  2. Power Off, power On of the module
  3. Start isegCANHVControl
  4. The update dialog should be open in a automatic way.
  5. Repeat the steps from point 7 to 10
Test the first module with the new firmware if the communication with the OPC server is possible (OPC QUALITY of the items are good).
