In the new release, the plug-in concept for measurement hardware can also be used for analysis operations. IPEmotion thus now supports three plug-in interfaces for the areas of measurement/signals, online/offline instruments and analysis operations. The plug-in interface for analysis operations enables users to integrate their own evaluation algorithms and calculation rules into the standard user interface. This allows complex evaluations to be encapsulated in a single operation, the calculation integrated into the overall analysis sequence and automatically executed. 

The extensions in the protocol and traffic measurement relate to the synchronisation of signal descriptions from different sources, which is particularly useful for measurements on vehicle bus networks. This is because at the moment in which the existing measurement task has to be synchronised with a new signal description, the synchronisation process compares the previous version with the current description file. This normally happens on message ID level, with the result that an existing channel will drop out of the synchronisation process if this is moved into a different message. However, if the check is performed on name level, the channel is always found, no matter which message it is assigned to. In addition, for traffic measurement and evaluation, the standard traffic BLF import format is available, allowing users to evaluate CAN, CAN-FD, FlexRay and traffic files offline via advanced filter functions.

The new templates implemented in the TEDS editor software for writing calibration data to sensors simplify the transfer of sensor scaling into the IPEmotion measurement configuration. Particularly for strain gauge sensors and accelerometers, a great deal of information is often required for the correct sensor parameterisation. If this information is stored in the sensor, it is immediately read out for sensor recognition and entered into the configuration. This reduces the susceptibility to errors and saves a great deal of time. Using the TEDS editor it is possible, via a compatible interface box, to write sensors with various templates with all the important calibration data such as scaling, feed, calibration date, validity, SN number, manufacturer, etc. IPEmotion thus offers the complete tool chain for the recognition and writing of TEDS sensors via the modules Sx-STG, Mx-STG2 6, Mx-SENS2 4 and M-SENS2.
