CANOpen Object Identification

[krishna123]

HI EveryOne,

I am Using NI PCI/2 2 port High Speed CAN Card. I am trying to communicate it with HMI712 from Selectron. The HMI works on CANOpen Protocol. I dont have CANOpen Library functions in labview. I have NI CAN Frame API in LabVIEW

How to write data to a specific object. i.e. for switching on LED in HMI. Firslty i have to write the index and sub index and then i have to write data to the object.

Can some one help me on how to specify the index and subindex and the data to CANOpen Slave.

Regards,
Krishna

Hi YouOne,

Well there are some LabVIEW Examples for the Frame API in this Forum:

But consider to buy the LabVIEW Library for CANopen. It saves you a lot of development time and headache. It is only a little more then 100 US $ and brings all the nice features you need.
