Software update boosts data logger operation

Version 3.22 of IPETRONIK's TESTdrive measurement software is available for download. This software update reduces the start-up time of the company's data logger (M-/S-LOG, FLEETlog), permits postprocessing of data during acquisition and enables the sending of status e-mails.

The measurement program supports OBD-II measurements on the vehicle, allows automatic import of signals into the DAQ lists with using  XCP service, and provides a new hardware driver for MultiDAQ measurement modules.

Depending on construction and size of the configuration, the start-up time of an IPETRONIK data logger can be up to 15 times shorter than normal. The latest TESTdrive version uses a special format to store the image of the system configuraton on the logger. This means, once initialized, later measurement starts will be executed faster because of the accelerated initialization process.

Another function added is the 'postprocessing during acquisition' feature which when activated, enables postprocessing functions – such as copying, zipping, encoding, splitting, and data transfer – to be executed during a running acquisition.

This is particularly advantageous for data acquisition series with short pause durations between single data acquisitions or for test bench applications. By allowing postprocessing in parallel with data measurements, data can be acquired continuously for extensive data acquisition series.

It also makes it possible to transmit data packets more effectively, it ensures that data can be transmitted reliably, even when network coverage is limited.

Once updated, the measurement program also enables users to send status e-mails. Such an e-mail contains the logger’s serial number as well as the number of the corresponding measurement file. Depending on the configuration, the e-mail attachment includes the log file, the measurement status file, as well as the min./max. and average values. This feature offers all important information to the user right after the end of data acquisition.

TESTdrive V3.22 supports OBD-II measurements on the vehicle. This means that an IPETRONIK data logger (M-LOG, S-LOG, FLEETlog) can now be used to acquire the vehicle’s operational data in accordance with the OBD-II diagnostics standard. Within the EU, implementation of the OBD standard has been mandatory for all new passenger cars since 2001 (for gasoline-powered cars) and 2003 (for diesel). For trucks, this standard has been obligatory since 2005.

This makes it possible to acquire the vehicle’s emission-relevant data and its most important operating data at a measurement rate of 1 Hz. To make this possible, the configuration software IPEmotion offers 96 predefined measurement signals, which can be active as needed to record data. Besides mere data storage, it is, of course, also possible to use familiar functions, such as performing online calculations and defining limit values.

The updated software allows automatic import of signals into DAQ lists with using XCP service. By activating the 'automatic service administration' in the IPEmotion options,  all active signals are automatically added to the three DAQ lists of the XCP service. After starting the acquisition in IPEmotion, this measurement values are displayed in the signal list.
