10.1.4. Output Format
The user can preset the format in which the data shall be output via the bus with the
Configuration Software ICP100
.
The data logger adjusts the data formats accordingly and makes sure that the data are available in the selected unit.
For the transmission in the ASCII- and PROFIBUS-format, the format settings listed in table 10.2 and 10.3 can be
chosen. At the transmission in the MODBUS-format the output format (integer or real) will automatically be confirmed
(Table 10.4). The coding of a real value in the MODBUS- and PROFIBUS-format is as follows:
Coding of the real value: x = s ee...ee mmm.....mmm
Value: (-1)
s

·1,m # : <1> <- 8 -> <----- 23 ----->
