To do this, import the corresponding GSDML
file into the customer’s Field Device Tool and
integrated it into the customer’s network
structure for the MQL system.
Two input and output bytes are available for
communication. Additionally, measurement
values are transmitted from the MQL system
to the machine control unit using 7 input
words (16-bit integer values).
Observe the following information:
o If the optional AM1000 aerosol monitor is
operated on the MQL system, data on the
prevailing aerosol density is transmitted
to the MQL system, from which it is fur-
ther transmitted to the machine tool (see
Chapter 7.1.1, Table 7).
8.2 Process image of MQL systems
Communication between the machine and
MQL system is performed using two output
and input bytes per aerosol generator and
seven input words (16-bit integer values).
The GSD/GSDML files for offer appropri-
ate configurations. Chapters 8.2.1, 8.2.2,
and 8.2.3 show the assignments of the
input and output bytes as well as their input
words.
o If the AM1000 is used, DIP switches 4, 7,
and 8 in the MQL control unit must be set
to the ON position
(see Chapter 7.1.1).
o Even if an aerosol monitor is not used,
analog measurement data can be trans-
mitted from the MQL system to the ma-
chine tool, though it is limited to the data
recorded in the MQL system.
The machine tool’s control unit receives dis-
crete information on the current state of the
MQL system via the two
input bytes
.
Through the
input words
, the machine tool’s
control unit receives digitalized measure-
ments as 16-bit integer values from the
MQL system (e.g., the variable for inlet pres-
sure) or the values of optional connected
components (e.g., AM1000) These values
are for information and can be utilized for
process monitoring.
The machine tool controls the MQL system
using the
two output bytes
.
