Syntax
ResetBit( tagName, numBitNumber )
tagName
numBitNumber
The name of an Integer tag where the bit value will be reset.
Note: To directly specify the name of a tag, rather than take the value of
the tag, you must enclose the tag name in double-quotes. For example,
ResetBit( "Second", 1 ).
A numeric tag or value specifying the position (0…31) of the bit to reset.
Returned value
0 No error
1 Invalid parameter
2 Tag does not exist
Notes
You can use the Bit field to read/write values from specific bits in an integer tag. For example, enter Second-
>b0 to access the LSB (Least Significant Bit of the Second tag), and Second->b31 to access the MSB (Most
Significant Bit of the Second tag).

Tag
Expression
ResetBit( "numSource", 4 ) // If the tag numSource held a value of 16, then the function returns 0 and
numSource holds a new value of 0.
ResetBit( "numSource", 1 ) // If the tag numSource held the value 19, then the function returns 0 and
numSource holds a new value of 17.
Round
Rounds numValue to the nearest integer.
