(I/O) interface

If MODE 4 is selected for the input signals, MODE 4 is
also set for the output signals and vice-versa.
** Status-controlled
*** Pulse-controlled
Digital control input modes:
MODE 0
Signals at the inputs are ignored.
MODE 1
E1 = Measurement period **
E2 = Start signal for master measure-
ment **
E3 = Takeover signal for master measure-
ment**
MODE 2
E1 = Start signal ***
E2 = Stop signal ***
E3 = Reset signal for clearing the MAX/
MIN memories**
MODE 3
E1 = Measurement period **
E2 = Signal for sending measured
value ***
E3 = Start and takeover signal for master
measurement **
MODE 4*
Enables the connection of control unit Millimar
S 1840/SG.
E1 = Measurement period **
E2 = Start signal for master measure-
ment***
E3 = Takeover signal for master measure-
ment ***
The functions can be assigned to the
digital control inputs either via the
Millimar or via the Windows based
configuration program D1000S.
While it is possible to assign specific
functions to a specific control input
via the Millimar, only preset function
packages (modes) can be assigned via
the D1000S. Here, the mode assigned
via the D1000S overrides the function
assignmets of the Millimar.
In case the Millimar function assign-
ment differs from the standard modes,
the Millimar transmits the "Mode 5"
signal while uploading data to the
D1000S. This means for the D1000S
„Do not override the Millimar function
assignment“.
The D1000S acknowlegdes this by
returning "Mode 5" to the Millimar
thus leaving the Millimar function as-
signment unchanged. If, however, the
D1000S sends a different mode, the
preset functions of this mode override
the Millimar function assignment.
