3.5.3 Evaluating temperatures in non-Windows operating systems
For applications that do not run in approved operating systems, temperatures can be evaluated using the B&R
MTCX Development Kit. The MTCX Development Kit also contains executable EFI sample programs.
The implementation guide describes only device-specific functions and not the main functions of the sample pro-
grams.
If the code from the sample programs is applied, the notes in the implementation guide for the TODO instructions,
I/O access functions, etc. must be taken into account!
Information:
For current B&R PC series (APC910 and later), the MTCX Development Kit can be downloaded at no
Sample programs and implementation guides for all other B&R PC series can be downloaded at no
3.5.4 Evaluating the measurement results
The recorded maximum temperature value of each individual sensor is not permitted to exceed the temperature
limit specified in the user's manuals.
If the temperature tests cannot be carried out in a climate chamber, they can be carried out in an office environment,
for example. It is necessary to record the ambient temperature, however. Based on experience gained at B&R,
the measured temperature values can be extrapolated linearly to the ambient temperature for passive systems
(systems without a fan kit). In order to also be able to extrapolate the temperature values for systems with a fan
kit, the fans must be running. The speed, etc. must also be taken into account.
If the temperature tests are carried out in a controlled climate chamber with a fan, the devices to be tested are cooled
by this fan and thus the measurement results are distorted. With passive devices, the measurement results are
therefore unusable. In order to be able to carry out temperature tests in climate chambers with fans without distorting
the measurement results, however, the fan of the climate chamber must be switched off and a correspondingly
long lead time (several hours) must be observed.
