Trans Mode according to the Transmission Type value:
0: at the occurrence of SYNC, the CANopen Option creates TPDO, which is
transmitted only when the data has been changed from the previous
value.
1~240: receiving SYNC for preset frequency, the TPDO is transmitted once.
252: at every occurrence of SYNC, data is updated to PDO, and TPDO is
transmitted when the master transmits a remote frame requesting TPDO.
253: receiving the remote frame from the master requesting the TPDO, data
is updated and TPDO is transmitted.
