There are two methods for process control:
1. With full storage of the process data, i.e. storing curves and results without
loss of data.
2. With a sequence optimized to the process, where, when there is a new
process, data storage is interrupted, so that the next process can be
started again even more quickly.
Both methods are described in the following sections, all signal diagrams are
based on positive circuit logic.

8.2 Test process sequence over time

a) Storing curves and results without loss of data
When you opt for the "without loss of data" storage method and want to save
the curves and/or results on the memory card or externally via the bus, the
following diagrams apply.
The ready signal is then only 1 again, if
− the process is completely finished,
− all the data have been fully stored and
− the device is ready to store the data for the next process.

Stores the statistical data present in the RAM
in the Flash EPROM
For MP85A(DP)-S only:
Specify which inputs must be used for the test
with regards to a switch test. The inputs must
be connected to a supply voltage via the
switch to be checked so that the status can be
detected. As the MP85ADP-S only has one
digital input available, you can use the four
so-called virtual inputs: The status of the vir-
tual input is set via a PROFIBUS command
(cyclical transmission).
The switching moments are also shown du-
ring a haptic test if an input is assigned
