Parameter Description Can this

(HRC3.1 only)
Caution:
Only the last active input is displayed when two inputs are active in
the range DI 01 – DI 09. Which is why only one input is active for
testing purposes. This can be viewed in the parameter
HowManyAct.
Note:
This parameter exists for the HRC3.1 only.
HowManyAct Displays the number of active inputs. Only one input may be active
in each range (Act 01 – 09 / Act 10 – 16) for a correct display of the
active inputs.
Example 1 (see figure for HRC3.1):
Act 01 – 09 = 6
Act 10 – 16 = 15
HowManyAct = 2
Î Only one input each is active for digital inputs in the range DI01
– DI09 and DI10 – DI16. Since a total of only 2 active inputs are
displayed under HowManyAct, the display is complete and correct:
DI 6 and DI 15 are active.
Example 2:
Act 01 – 09 = off
Act 10 – 16 = 15
HowManyAct = 2
Î Two inputs are active for the digital inputs in the range DI 10 –
DI 16. A concrete comment on active inputs is not fully possible.
Example 3:
Act 01 – 09 = 6
Act 10 – 16 = 15
HowManyAct = 3
Î Two inputs are active for the digital inputs in the range DI 10 –
DI 16. A concrete comment is therefore not possible.
