Important Notes:
* RS receiving operation is only possible in the CANopen “operational”
state!
* After entering the operational state:
* The receive buffer is cleared.
* Any previous data remaining in the receive buffer are deleted.
* Object 2001
h
is deleted entirely (all bytes = 0).
=> The toggle bit of the sub-frame to be transferred with the
first PDO is set to 1.
* The end of the RS receive frame is detected by means of the
“receive timeout” (can be set with the DIP switch). In order to assure
detection of the end of the frame, no characters may be received
during the selected time period.
* RS receive frames may not exceed a length of 200 bytes.
* No further RS frames may arrive while the RS receive frame is being
transmitted via the CANopen interface (these would otherwise be
deleted).
