This parameter defines the contact position when switch on the switch, which will be triggered by the
communication object “switch, X”. When enabling “input 0” in the logic function, it will use the communication
object “switch, X” to modify the value of “input 0”, rather than triggering the switch operation. In this case, this
parameter is no significance to the switch. Options:
Open
Close
The parameter only works after the object “Switch x” receiving value, and defines the direction of the contact
after receiving it. The details can be found in the below form:
Parameter options
“Switch, X” object value =1
“Switch, X” object value =0
Open
Contact open(OFF)
Contact close (ON)
close
Contact close (ON)
Contact open (OFF)
Since the switch and logic functions share the same object
“
switch, X
”
, thus need to understand the
relationship between them, the control sequence shown below (the logic functions, please refer to the
following chapter describe):
Object “Switch, X”
Object “Input 1 of logic, X”
Object “Input 2 of logic, X”
