ACK frame in CANopen library

I am using CANopen library to develop code in LV2009 and PCI8511 card. 

 

The proportional valve connected to the system issues a NMT Boot Up message 0x701 with zero Data byte. I now have to acknowledge this to proceed further. But there does not seems to be any function the CANopen Library to do this. ( Since I am able to read the 0x701 boot up message the hardware link up is OK )

 

How to generate an ACK frame using CANopen library ?

 

Thanks

Hi,

 

Typically if a CANopen slave device uses heartbeat alive meassages it will start sending a single heartbeat message when the master initializes it to pre-operational state. That means you ahve to setup the heartbeat protocoll before you do send the state change command in order to handle the heartbeat protocoll correctly. There is a Library available for heartbeat that installs with the driver.
