    10.1.2 File structure There are two file categories: − files containing structured information, whose fields have an assigned type (structured files) − files containing “raw” data, without defined fields, or field types (raw files) Raw files are distinguished by the RAW FILE flag in the record definition structure 10.1.3 Structured Files Structured files are mostly used to save on disc the values of variables allocated in the device volatile memory.

    10.1.5 Homogenous files Homogenous files always contain a single “variable definition structure” allocated in the header and contiguous to the “record definition structure”. All the descriptors contained in this structure define a variable that can be allocated either in the file header (in the descriptor) or in the data area. The area where the variable is allocated is described by the status of the external allocation flag contained in the descriptor.

    11.9 Output format This command gives the possibility of rendering a file content into a structured and commented format for easier readability. The file structure is the one better described in the instrument manual; it is divided in records with the first one describing the structure of the file itself, the others records being the data. The comments, or variable descriptors, used are taken from the X3M_01.map file that is resident in the same folder of the xmbf.exe file.
  • Page 135 The comments are identified by the // characters. Should this be a configuration file, the data part may be edited with Notepad, reconverted into a binary file by means of the hex2bin command and stored in the instrument by means of an Upload command. This is the procedure that enables to modify the configuration of the various Services supported by the instrument.
