Bosch Rexroth ID 40 Manual page 43

6.4.2.1 Single transmit
Write commands that are executed only once for the next MDT entering the HF field
of the SLK are known as single transmit (ST).
6.4.2.2 Multiple transmit
Multiple transmit (MT) commands are repeated for all subsequent MDTs. This makes
them particularly suitable for initializing data carriers, e.g., at the first process
station of an assembly line.
Multiple transmit automatically overwrites every MDT passing the SLK without
prompt on the fieldbus. There is the risk that accidentally either important data
on the MDT is deleted or incorrect data is entered on the MDT.
