Description :
For reference variable of FLAG type:
The state of the left link is copied in the right link. The state of the associated Boolean variable (indicated with reference) is ON, from an evaluation of this element until the next, when on the left link is revealed a transition from OFF to ON. The state of the associated Boolean variable (indicated with reference) will be OFF all the other times.
Important
If at the first evaluation of this element is revealed the state of ON in the left link the programmable controller system (Qmove) will ignore that value until it will reveal the state of OFF. At this point the positive transition-sensing coil will start to work normally.
For reference variables of BYTE, WORD, LONG and SINGLE type :
The state of the left link is copied in the right link. The value of the associated variable (indicated with reference) is 1 (one), from an evaluation of this element until the next, when in the left link is revealed a status transition from OFF to ON. The value of the associated variable (indicated with reference) will be 0 (zero) all the other times.
Important
If at the first evaluation of this element is revealed the state of ON in the left link the programmable controller system (Qmove) will ignore that value until it will reveal the state of OFF. At this point the positive transition-sensing coil will start to work normally.
Important
The QEM ladder editor allows the use of a reference used with a positive transition-sensing coil in coils of other types or as output value of a function block, in that case the value of the associated variable (indicated with reference) depends from the interaction from the various functionality.
