Setting substitute values
Note
For output ranges 4 to 20 mA and 1 to 5 V you must set the substitute value
E500
H
so that the output remains de-energized (refer to Tables 4-35 and 4-37 on
pages 4-26 and 4-27).
The representation of the substitute values corresponds to the analog value
representation. You should observe the relevant range limits when setting the
substitute values.
Output methods and output ranges
The table below contains all the output methods and output ranges of the analog
output modules and their codes. You must enter these codes in bytes 2 to 5 of
data record 1 (refer to FigureA-17).
