21 Data Format The data are recorded in the MDF-Format. Two files are generated. One binary file with the ending '.DAT' and one belonging description file with the ending '.MDF'. The description file is necessary for the data viewing software PVIEW from Stiegele Datensysteme GmbH. The binary file can be used from other data display or data analysing systems that are able to import digital values. Format of the Binary File (.DAT) Definition: LB= Low Byte, HB=High-Byte First the Low-Byte and then the High-Byte of a channel is recorded. The range of a 16 bit system is from 0 to 65535, the range of a 12 bit system is from 0 to 4095 Assignment to the analog values: Excitation 100% (correspond to analog output +10V) digital value for 16 Bit-Systems 3891 for 12 Bit-Systems Excitation 0% (correspond to analog output 0V) digital value for 16 Bit-Systems 2048 for 12 Bit-Systems Excitation -100% (correspond to analog output - 10V) digital value 3277 for 16 Bit-Systems 205 for 12 Bit-Systems Exciation [%] = (Digital-Value ) / for 16 Bit-Systems Exciation [%] = (Digital-Value ) / 18,43 for 12 Bit-Systems Data File Values out of this range are not within the measuring range and cannot be transmitted correctly.
