As shown in picture 7.3.3 it can be selected with di.01 whether the inputs are switched by terminal strip (default)

or via parameter di.02 . The two parameters are bit-coded, i.e. in accordance with the following table the asso-

ciated value of the input must be entered. With several inputs the sum is to be formed.

3.4.4 Input terminal status (ru.21), internal input status (ru.22)

The input terminal state (ru.21) displays the logical levels at the input terminals. It is irrelevant whether the in-

puts are internally active or not. If a terminal is controlled, then the appropriate decimal value according to the

table below is output. With several active terminals the sum of the decimal values is output.

The internal input state (ru.22) displays the logical state of the digital inputs set internally for processing. If an

input is set, the appropriate decimal value according to the table 7.3.1 is output. If several inputs are set, the

sum of the decimal values is output.
