7.3 Control and automation software
A terminal program can be used to communicate with the constant tem-
perature equipment. For example, the freeware
RealTerm
, which can be
downloaded from the following address: https://realterm.sourceforge.io/
The following settings are required to establish a connection to the constant
temperature equipment:
1.
Start the terminal program on the connected system.
2.
Open the
Port
tab:
Select the preset baud rate in the
Baud
field.
Select the relevant COM port in the
Port
field.
Press
Open
to confirm your selection.
3.
Activate the option
Half Duplex
in the
Display
tab.
4.
Open the
Send
tab and activate the options
+CR
and/or
+LF
in the
EOL
area.
5.
Send a test command such as the read command "TYPE” to the
constant temperature equipment.
If the device type designation, for example "ECO", is received in
response, the connection has been set up correctly.
The program development tool LabVIEW
®
from National Instruments
https://www.ni.com/de-de/shop/labview.html can be used to create conven-
ient, personalized control software or automation software for operating
constant temperature equipment. In order to cater for the programming
needs of the interface used here, drivers designed specially for LABVIEW
®
can be downloaded free of charge from the download area of its LAUDA
website: https://www.lauda.de/de/services/download-center/filter/Software
