Function - Test a bit of an integer register.
IN : ANY
8 to 32 bit integer
BIT : DINT Bit number (0 = less significant bit)
Q : BOOL Bit value
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 LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung is the output of the function.
Q := TESTBIT (IN, BIT);
(* The function is executed only if EN is
