Function A 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. - Pack bits in a byte.

Inputs

Input	Data Type	Range	Unit	Default	Description
IN0	BOOL				Less significant bit.
IN7	BOOL				Highest significant bit.

Outputs

Output	Data Type	Range	Unit	Description
Q	USINT			Byte built with input bits.

Remarks

None

FBD Language Example

FFLD Language Example

The input rung is the IN0 input.
- The output rung (ENO) keeps the same value as the input rung.
ENO keeps the same value as EN.

IL Language Example

In the IL "Instruction List" This is a low-level language and resembles assembly Language, the input must be loaded in the current result before calling the function.

Op1: LD "Ladder diagram"
Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them    IN0
