The communication object "Input 1" can be set to the size "1 bit" or "1 byte". The default
setting is "1-bit". If the size "1-byte" is selected, the receipt of a telegram with a value
greater than "0" always means that a logical "1" is placed on the input.
12.26.4 Parameter input 1 – Initial value input 1
Options Initialized with 0
Initialized with 1
The "Initial value input 1" parameter specifies which input value shall be pending on the
input after the initial startup and after return of voltage. You can select between the logical
values "0" and "1". Thus, no undefined states can arise.
12.26.5 Parameter input 1 – Logic input 1
Options Normal
The input signal can be inverted via the "Logic input 1" setting.
Note: For a 1-byte size input object, the "inverse" setting means that only upon receipt of
the value "0" will a logical "1" be present on the input. All other values (1 to 255) cause a
logical "0" on the input.
12.26.6 Parameter input 2 – Object type input 2
Options 1 bit
The communication object "Input 1" can be set to the size "1 bit" or "1 byte". The default
setting is "1-bit". If the size "1-byte" is selected, the receipt of a telegram with a value
greater than "0" always means that a logical "1" is placed on the input.
12.26.7 Parameter input 2 – Initial value input 2
Options Initialized with 0
Initialized with 1
The "Initial value input 1" parameter specifies which input value shall be pending on the
input after the initial startup and after return of voltage. You can select between the logical
values "0" and "1". Thus, no undefined states can arise.
12.26.8 Parameter input 2 – Logic input 2
Options Normal
The input signal can be inverted via the "Logic input 1" setting.
Note: For a 1-byte size input object, the "inverse" setting means that only upon receipt of
the value "0" will a logical "1" be present on the input. All other values (1 to 255) cause a
logical "0" on the input.
