Measuring methods and measuring ranges
The table below contains all the measuring methods and measuring ranges of the
analog input module and their codes. You must enter these codes in bytes 2 to 13
of data record 1 (refer to Figure A-12).
Note
Please note that the analog input module must be wired in accordance with the
measuring range and at the front connector correspondingly!
