6.3.5 Graphical test operation
In the "Graphical test operation" menu (M59) you can perform measurements in one or more
measurement programs and use the recorded measurement curve(s) to define the graphical evaluation
elements such as "Window", "Trapezoid", "Threshold" and "Envelope". The 10 most recent measurement
results from each measurement program are saved. You can select
[CrvArray]
to display this set of
recorded measurement curves as a curve array. When calculating an envelope, the DIGIFORCE
®
9311
uses these measurement curves as the basis for generating the "Envelope".
Note:
Note that on activation of the "IN_AUTO" control input, the "Graphical test operation" menu
(M59) will close automatically and the DIGIFORCE
®
9311 will switch to measurement mode. In
"Graphical test operation", the other PLC I/O control signals respond in exactly the same way as
in measurement mode, and the online switching points are also active.
