oFlipFlop Object

In normal operation, the oFlipFlop Object evaluates the oLogic Object that the Input1 and Input2 properties point to and perform a standard flip-flop function based on their values once every Object List Loop.

To perform the flip-flop function the value of Input1 is evaluated first. If Input1 is 1, the Result property is set to 1.  If Input1 is 0 then Input2 is evaluated.  If Input2 is 1, then the Result property is cleared to 0. If Input2 is 0, then no changes are made.  

If the property option "C" is used, then the operation is modified so that this function only occurs once each time an oLogic Object transitions.

• C specifies that a clocked version of the object is used.

The following table lists the properties of the oFlipFlop Object:

Property	Description
Operate	A value that selects whether or not the Output objects are updated with the result of the logic operation. Object Class:  oOperate   Value Range:  0 - 1 Data Type:  Numeric   Default Value:  0 Operate Constant Description 0 cvOff The operation is not performed. 1 cvOn The operation is performed.
Input1	A pointer to an oLogic Object whose value will used to set the result. Object Class:  oLogicPtrI   Value Range:  Any oLogic Object Data Type:  Pointer   Default Value:  Null
InvertIn1	A value that selects if the Boolean value is inverted before used. Object Class:  oSelect0to1L   Value Range:  0 - 1 Data Type:  Numeric   Default Value:  0 InvertIn1 Constant Description 0 cvFalse The value of the Input1 Object is not inverted. 1 cvTrue The value of the Input1 Object is inverted.
Input2	A pointer to an oLogic Object whose value will used to reset the result. Object Class:  oLogicPtrI   Value Range:  Any oLogic Object Data Type:  Pointer   Default Value:  Null
InvertIn2	A value that selects if the Boolean value is inverted before used. Object Class:  oSelect0to1L   Value Range:  0 - 1 Data Type:  Numeric   Default Value:  0 InvertIn2 Constant Description 0 cvFalse The value of the Input2 Object is not inverted. 1 cvTrue The value of the Input2 Object is inverted.
Output	A pointer to an oLogic Object whose value will be updated with the result of the operation. Object Class:  oLogicPtrO   Value Range:  Any oLogic Object Data Type:  Pointer   Default Value:  Null
Result	The result of the Flip-Flop. Object Class:  oLogic   Value Range:  0 - 1 Data Type:  Numeric   Default Value:  0 InvertIn Constant Description 0 cvOff The value of Input2 has been set. 1 cvOn The value of Input1 has been set.
Process Clock	See Clocked Objects for detail Object Class:  oClockedOperate   Value Range:  0 - 1 Data Type:  Numeric   Default Value:  0 Availability: oFlipFlopC
Address	Returns a pointer to the address of the oCounter Object instance. Object Class:  oAddress   Value Range:  0 - 127 Data Type: Pointer (Read Only)   Default Value:  Address of Object
