US/U 4.2, GH Q631 0070 R0111
The following section describes all the parameters which are visible if the
input is operated with the function “Switching sequence”. A switching sequence
enables the stepwise modification of several values via a single operation.
Next switching level = actual value of objects ± 1
+ 1 → Switch upwards
– 1 → Switch downwards
4.11.1 Parameters
Parameter: “Connected contact type”
This parameter defines whether the contact at the input is a normally open
contact or a normally closed contact.
Parameter: “Number of objects”
The number of levels (max. 5) is identical to the number of communication
objects: objects “Value 1” to “Value n” are enabled.
Parameter: “Type of switching sequence”
The switching sequence can be selected here. Each sequence has other
object values for each switching level. The following switching sequences are
possible (a detailed description can be found in section 5.7):
Type of switching sequence
Example
“sequentially on/off (one push button)” ...-000-001-011-111-011-001-...
“sequentially on/off (several push buttons)” 000-001-011-111
“All combinations” ...-000-001-011-010-110-111-101-100-...
The example is based on the status of three objects (“0” = OFF, “1” = ON).
A table of the grey code can be found in section 7.1.
