Examples
Tag Name
Expression
Tag Round( "345.87" ) // Returned value = 346
Tag Round( "65.323" ) // Returned value = 65
SetBit
Sets a single bit in an Integer tag to 1.

Syntax
SetBit( tagName, numBitNumber )
tagName
numBitNumber
The name of an Integer tag where the bit value will be set.
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,
SetBit( "Second", 1 ).
A numeric tag or value specifying the position (0…31) of the bit to set.
Returned value
0 No error
1 Invalid parameter
2 Tag does not exist
Notes
You can also use the Bit field to read/write values from specific bits of 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).
