7.3 Evaluating temperatures in non-Windows operating systems
For applications that do not run in Windows, temperatures can be evaluated with the help of the B&R implementation
guide. In addition to the implementation guide, there are also programs available in MS-DOS.
The implementation guide only describes device-specific functions, not the main functions of the sample programs.
If code from the sample programs is used, it is important to observe the notes in the implementation guide regarding
TODO statements, I/O access functions, etc.
Information:
Sample programs and implementation guides for all B&R Industrial PCs and Power Panels are available
at no cost from the B&R website (
7.4 Evaluating the measurement results
The maximum temperature value recorded by each sensor is not permitted to exceed the temperature limits spec-
ified in the user's manuals.
If the temperature tests cannot be performed in a climate-controlled chamber, they can still be performed in an
office environment. However, it is necessary to measure the ambient temperature in this case. Experience at B&R
has shown that values measured on passive systems (systems without a fan kit) can be projected linearly based
on the ambient temperature. In order to be able to project the temperature values for systems with a fan kit, the
fans must be running. It is also important to take values such as speed into consideration.
If the temperature tests are performed in a climate-controlled chamber with fans, the fans will cool the devices
being tested and distort the results. Measurement results for passive devices are therefore unusable. In order to
obtain accurate results in climate-controlled chambers with fans, the fans must be turned off and the device must
be allowed to run for a sufficient amount of time (several hours) before beginning the test.
