There may be only one active SDO Upload Request. If more Upload Requests are
triggered via requestVariableValueFromOwner, they will be queued until either a
timeout happens (see below) or the ECU answers with a SDO Upload Response.
·
The ECU has to answer to an SDO Upload Request within 100ms. If the answer
takes longer or is not answered at all, an SDOAbort message will be sent (with
error code SDO Protocol Timeout).
·
The CANopen stack will only react to SDO Upload Responses if an SDO Upload
Request has been sent before (simulating a request with e.g. CANFreestyle will
not work).
