EPOS2 USB to can gateway

[Massif]

  Dear,

In my application, I used the maxon motor VIs to control 3 cards:  EPOS2 with an usb to canOpen gateway protocol.

• The first card is connected in USB.

• The 2 others cards are connected in canOpen. 
  First card =node 1,
  Second card = node 2,
  Third card = node 3.

The VI 'InitializeDlg VI' proposed only this type of configuration to establish the connection of my cards. (see the attached picture).

The VI don't  propose a USB to can protocol.

I can connected the first time all the card when I run the soft.

If the soft is interrupted (like an emergency stop) and I run this soft again, only the first card is detected. (the canOpen connection is lost).

How can I closed the previous the first canOpen connection and created a new one)?

Is there a mistake in my configuration?

Massif,

Thank you for posting on National Instruments' Forum.

Maxon Motors's VIs include a function close. Did you try to use this VI to stop the connection, and create a new one afterward?

   Dear Romain,

I try to close the connection before, but it's doesn't works.

The document 'EPOS Windows 32-Bit DLL.pdf' (August 2010) explain how to configure the cards.

See the picture.

The support of maxon explained that I should used:

DeviceName 'EPOS2'

ProtocolStackName 'MAXON SERIAL V2'

Interface Name 'USB'

But the VI 'Initialize.vi' doesn't recongnise the ProtocolStackName 'MAXON SERIAL V2'.

The VI 'InitializeDlg VI' doesn't propose the 'MAXON SERIAL V2'.

Is there an update of the EPOS' Library?

To update instrument's driver EPOS, I advise you to follow this link : here .

Did you try to use the USB only? This problem appears just with USB connection?

I give you an other link : here .

I wait for your reply.

 It's working with new dll 'EPOS2.dll'

Thanks

Hi,

i've developed a application in rs-232 protocol with only one card but i want to connect another card via can  and i don't know how to use can gateway protocol exactly.

i don´t know if i can use the same blocks of Epos' library. Once the second card recognition is started, should i use the CAN blocks?¿ or to continue using the RS232 protocol ??

i don't know anything about Can programming.. sorry

i would like to know a simple example with the basic steps or how i could do it....

Regards

  Hello,

You can use the same VI.

You have just to configure you cards with the Rs232 protocol (let's see protocolStackName).

Hi, 

i'm trying to comunicate the two cards but i can´t. I don't know if i can connect the next way:

Card 1 : USB

Card2 : CanOpen

  

A error appears: Bad Interface Name..

Massif, how did you connect it fisically?

Regards 

[Squal]

Someone have any idea about this?
