Fig.11 Parameter window “switching sequence, X”
Parameter “Connect contact type”
This parameter defines whether the contact at the input is a normally open contact or a normally
closed contact.Options:
Normally closed
Normally open
The parameter introduced in this chapter is use “Normally open” as the example, the normally close
is just opposite.
Parameter “No. of objects”
This parameter defines the number of objects, which is the number of levels, it is identical to the
number of communication objects.Options:
2level
3level
4level
5level
For example, parameter “3level” means there are 3 communication objects: “level-1”, “level-2”,
“level-3”. The first operation modified the value of “level-1”, the second operation modified the value of
“level-2”, the third operation modified the value of “level-3”, the fourth from modified the value of
“level-3”……, the switch sequence is: 000,001,011,111,011……The data send on the bus is the value of
the communication object that after modified, which is the alterative data. The communication object
“level increment/decrement, X” is used to increase or decrease the switch level, ‘1’ means increase 1
level and ‘0’ means decrease.
Different options have different communication objects and different switch levels, but their
management are similar in the case of the same switch sequence type.
