<div class="markdown_content"><p>Hello everyone,<br/> I am trying to implement a CAN layer 2 FB for a Cross Control Pilot VI where the manufacturer at this stage is providing the normal CANopen interface.<br/> Did follow the example from Codesys CANbusAPIExample but it seems that this require to periodically call the method CL2.Read().<br/> So, even if the timer is set to 5ms but the program which implements this call is run every 20ms, this will create a min latency of 20ms on the CAN bus.<br/> My question is if there is any way to use interrupt or call back so to run a message processor everytime a specific CAN ID is received.<br/> Thank you to everyone able to help.<br/> Cheers</p></div>
