29
Range - letters and numerals, max.16 characters
Default
value
- Name of resource (I1…I8)
Comments - Using friendly names facilitates recognition of destination
and appropriate settings.
7.2.5.2.2.2. Operation mode
Function - defines operating mode for inputs I1…I8
Data type - selection list

Function - Defines (in seconds) value of min. duration of
altered state on input in order to consider state to
be stable.
Data type - number
Range - 0,00…163,83 [s]
Default value -0,1 [s]

7.2.5.2.2.2.2.1. Counting direction
Function - defines counting direction
Data type - selection list
Range - Up
A pulse on input increases value of counter register
Down
A pulse on input decreases value of counter register
Default value - Up
