Data Logger SL-Data composed by GAB H844 that acquires both Analog and Digital lines from the field and an S-LOG capable to store data and time on a Secure Digital card.


SL-Data is a product capable to acquire analog data, supplied by the field, and to save them on a removable memory card , like the SD (Secure Digital) and MMC (Multi Media Card) types.
This product is the result of numerous experiences, collected in many years by grifo®, during the development of Data Logger applications. The equipment acquire and save different analog signal in a simple, reliable and cheap manner. Moreover it allows to examine and/or process the saved information, later and in a different place.

The logged data are saved on the memory cards managed by S-LOG, that are the SD and MMC, with FAT16 format.
The logged data can be moved to a PC through a simple extraction of the memory card and a following insertion on a PC provided of a standard multicards interface. The data are availbale under file/s with ASCII format and they are organized in order to be opened with EXCEL spread sheet. Then these data can be saved in different files, or they can be examined, processed, printed, arranged, registered, displayed on graphs, etc. according with user requirements.

The SL-Data is composed by a group of hardware, firmware and software. This division allow the customers to select two different working modalities:
A) Use the package directly, as it has been supplied, by taking advantage of the provided configurations in order to satisfy the application requirements.
B) Modify the program Source in order to change, or add, some new required functionalities.

The operative features, already available or to be added, of the SL-Data are briefly described below.

  • Logging of analog signals supplied by temperature, pressure, humidity, flux, capacity, position, voltage, corrent, consumption, etc. transducers.
  • Closed loop controls that mantain the checked signals to a preset set point.
  • Alarm controls with periodic saving of their status.
  • Logging of digital signals supplied by switches, selectors, proximities, allarms, stroke ends, etc.
  • Pulses count and saving of their number, frequency, distribution, etc.
  • Management of serial communications with different protocols (RS 232, RS 422, RS 485, CAN, I2C BUS, etc.) and saving of exchanged data.
  • TTL digital signals controller, either input or output, that can be connected to other electronic circuits, with saving of the same signals status.
  • Teleacquisition of the input signals on a long distance communication line, either standard or wireless.
  • Telecontrol of the available signals on a long distance communication line, either standard or wireless.
  • etc.
  • The firmware and the software normally provided with SL-Data acquire and save the analog inputs available on GAB H844, coupled with a selected Mini Module. The supplied program, even in source format widely remarked, includes all the necessary Procedures and Data Structures and allows the user to develop his firmware and to satisfy his specific requirements. In this manner the SL-Data considerably reduces the development time of data logger applications.

    A comfortable configuration mode let the user arrange the SL-Data for the application to develop. As an example, it defines the type of the connected analog signals, the acquisition time and mode, the features of the physic values acquired (engineering format), etc. Normally the configuration mode is used only one time before the installation of the complete system.

    One of the most important features of SL-Data is that it is a ready to use product: the user is not forced to know the selected and used hardware. Thanks to the Utility programs and the sources provided with the product, it is possible to set up, test and use the data logger in few minutes.


    The most important features of SL-Data are summarized in the following points. In order to simplify the description we define:
    - Acquisition Hw -> system dedicated to field signals connection (usually GAB Hxxx + Mini Module).
    - Saving Hw -> system dedicated to data saving (S-LOG: for details please proper documentation).

    For further information please refer to proper SL-Data user's manual.
