Description:

The oLogic Object manages a Boolean value so that it can be used in a Virtual Circuit.

The following table lists the size and availability of the oLogic Object.

	Object	Size	Description	A1	A2	B1	B2	C1
	oLogic	1 Byte	A linkable Object used for virtual circuits.	x	x	x	x	x

Operation:

The oLogic Object is a specialized Boolean value configured so that a Virtual Circuit can read and write the 1-Bit value.

Properties:

The following table lists the properties of the oLogic Object:

Property
Description

Value

The value of the 1 bit.

Object Class: oVar1 Value Range: 0 - 1

Data Type: Numeric Default Value: 0

IsSet

A value that indicates if the bit is 1.

Object Class: oProperty Value Range: 0 - 1

Data Type: Numeric (Read-Only) Default Value: 0

IsClear

A value that indicates if the bit is 0.

Object Class: oProperty Value Range: 0 - 1

Data Type: Numeric (Read-Only) Default Value: 0

Address

Returns a pointer to the address of the oLogic Object instance.

Object Class: oAddress Value Range: 0 - 127

Data Type: Pointer (Read Only) Default Value: Address of Object

Example:

The following examples use the oLogic Object.
