TESTBIT
Inputs
IN : ANY 8 to 64 bit integer register
BIT : DINT
Bit number (0 = less significant bit)
Outputs
Q : BOOL Bit value
Remarks
Types LINT, REAL, LREAL, TIME and STRING are not supported for IN and Q. IN and Q must have the same type. In case of invalid arguments (bad bit number or invalid input type) the function returns FALSE.
In FFLD language, the operation is executed only if the input rung (EN) is TRUE. The output rung is the output of the function.
