Measuring methods and ranges
The table below contains all the measuring methods and ranges of the analog input module,
including their codes. Enter these codes at bytes 2 to 13 in data record 1 (refer to the
previous figure.)
Note
The front connector of the analog input module must be wired in accordance with the
measuring range!
