You can directly to the WBM page for configuring this tag type.

Figure 4-3 Example of the symbol of digital input 0
The information has the following meaning:
● Identifier
–
E = configured as an event counter (only digital input 0 or 1)
– C = configured as consumption counter (only digital input 0 or 1)
– L = Logging enabled
In the example (graphic): Configured as an event counter, logging not enabled.
● x / y
Frequency of the use of the address in the user program:
–
x = Use as an input
– y = Use as an output
Digits show the frequency of use.
The minus sign means that no use as an output is possible.
In the example (graphic): used once as input / cannot be used as output
Among other things you can see here when an address is not used at all in the program.
● Update cycle
The individually configured update cycle as the product of the basic cycle and reduction
factor is displayed.
In the example (graphic): 16 minutes
