Output Format
The data format can be user defined by means of configuration
software COMBILOG.EXE. The data logger adjusts the data
formats accordingly and makes sure that the data are available
in the selected unit.
For transmission in ASCII-format, the format settings listed in
table 11.2 can be chosen. By transmission in MODBUS-format
the output format (integer or real) is recognised automatically
(table 11.4). The Coding of a real value in MODBUS-format is
as follows:
Coding of the real value:
x = s ee...ee mmm.....mmm
