The basis for the control, measuring and evaluation operations on the screen is the signal flow chart,
in which the physically present laboratory instruments are shown as functional units. Other virtual
functional units for control , measured value calculation and result display can be integrated and
interconnected depending on the measuring task.
Creation or modification of a measurement sequence schedule may be limited by activated User
Managment !
The following topics can be selected for the generation, configuration, execution and archiving of
the signal flow charts:
(In this document the terms "configuration" or "configuration file” are used in places. They should
be understood in the same way as measurement sequence schedule.)
General information on generating signal flow charts
Usually, the functional units are positioned so that a horizontal signal flow results from left to right. This
means that the control functions (red functional units) are to be arranged on the left-hand of the
working area and the result displays (green functional units) more on the right-hand side. Therefore,
the "laboratory instruments" (blue functional units), by which the set-up of the signal flow chart usually
begins, should be placed as close to the center of the working area as possible. The yellow functional
units for averaging and arithmetical operations must be positioned between the laboratory instruments
and the result displays.
With this basic structure, any complex signal flow charts containing up to eight laboratory instruments
(blue functional units) can be generated with labworldsoft.
Selecting functional units from the tool bar
Carry out the following actions with the OHIW PRXVH EXWWRQ :
1. Select the first functional unit in the blue field, e.g. /DERUDWRU\ LQVWUXPHQW 5(7 FRQWURO :
The enlarged symbol for the magnetic stirrer RET control appears in the upper left-hand
corner of the working area. A number field is located on the right-hand side which
corresponds to an origin path for a measuring result (basic setting).
2. Select the second functional unit in the yellow field, e.g. for $YHUDJLQJ : The enlarged
symbol appears under the laboratory instrument RET control. Number fields representing
an input and an output are located on the left and right-hand side (basic setting).
3. Select the third functional unit in the red field, e.g. Control unit for UDWHG YDOXH VHWWLQJV .
The enlarged symbol of the control unit (slide controller) appears in the working area. A
number field representing the output path for the controlling variable is located on the
right-hand side.
4. Select the fourth functional unit in the green field, e.g. Result unit for JUDSKLF GLVSOD\ .
The enlarged symbol of the graph display appears in the working area. A number field is
located on the left-hand side which corresponds to an input path for a measuring variable
(basic setting).
