SETBIT

FunctionA function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Set a bit in an integer register.

Inputs

IN : ANY 8 to 32 bit integer register
BIT : DINT Bit number (0 = less significant bit)
VAL : BOOL Bit value to apply

Outputs

Q : ANY Modified register

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 the value of IN without modification.

In FFLD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung.

ST Language

Q := SETBIT (IN, BIT, VAL);
