nd
parameter: selects function/enters volume
The DOS command is used for controlling Dosimats and Dosinos. Up
to 3 Dosinos or Dosimats can be addressed individually or simultane-
ously via the MSB bus control.
The 1st parameter selects the dosing device and the corresponding
dosing port, at which the required function is to be carried out. If '*' is
entered then the default port for the corresponding function will be used
(e.g. dosing port = 1, filling port = 2, etc.).
