Set Variable

Item	Name	Description
A	Variable	The Variable you wish to perform the operation upon.
B	Operation	User selectable operation, some of which require the 2nd Operand and some that do not. Details on available operations below.
C	2nd Operand	Used selected operations that require a 2nd value or variable. Note that 2nd Operand position automatically appears or disappears depending on the Operation selected.

Available Operations

Selection	Operation	Description
=	A = C	Instruction copies the value of 2nd Operand and stores the result in Variable
+1	A = A + 1	Add 1 to the initial value of Variable and store the result in Variable
-1	A = A – 1	Subtract 1 from the initial value of Variable and store the result in Variable
+=	A = A + C	Add the value of the 2nd Operand to the initial value of Variable and store the result in Variable
-=	A = A – C	Subtract the value of the 2nd Operand from the initial value of Variable and store the result in Variable

In this example we are setting the value of “My_DINT” to the value 3000.
In this example we are incrementing the value of “My_DINT” by 1. Similarly we could have selected the -1 operation and then decremented the value of “My_DINT by 1. Please note that the 2nd Operand is not needed for this operation .
In this example we are adding 5 to the initial value of “My_DINT” and placing the result in “My_DINT”
