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 inverted (NOT operation) when on the left link it is noticed a state transition from OFF to ON.
Important
It at the first evaluation of this element is revealed the state of OFF in the left link the programmable controller system (Qmove) will ignore that value until it will notice the state of ON, at this point the negative transition-sensing coil will start working normally.
For reference variable of BYTE, WORD, LONG e SINGLE type:
The state of the left link is copied in the right link. The state of the associated variable (indicated with reference) is inverted (NOT operation) when on the left link it is noticed a state transition from OFF to ON.
Important
It at the first evaluation of this element is revealed the state of OFF in the left link the programmable controller system (Qmove) will ignore that value until it will notice the state of ON, at this point the negative transition-sensing coil will start working normally.
Important
The QEM ladder editor allows the use of a reference used with a negative 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 functionalities.
