The commands are always triggered by the DPV1 master by means of a corresponding entry in its
output data area. The controllere responds then in the input data area of the host system.

If a command is to be executed, the value 65

must be entered in the command request. Changing
the command number does not start the execution. If a command is to be executed several times, the
user ID must be changed accordingly, e.g. by counting up. Before starting a command it should be
verified in the command status whether the previous command has been completed.
