or_mask

PLCopen motion icon

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. - Performs a bit-to-bit Boolean OR between two integer values.

Inputs

Input	Data Type	Range	Unit	Default	Description
IN	ANY				First input.
MSK	ANY				Second input. (OR mask)

Outputs

Output	Data Type	Range	Unit	Description
Q	ANY			OR mask between IN and MSK inputs.

Remarks

Arguments can be signed or unsigned integers from 8- to 32-bits.

FBD Language Example

FFLD Language Example

In the FFLD "Free Form Ladder Diagram" Language, the input rung (EN) enables the operation.
- The output rung keeps the state of the input rung.
- The function is executed only if EN is TRUE.
- ENO has the same value as EN.

IL Language Example

In the IL "Instruction List" This is a low-level language and resembles assembly Language, the first parameter (IN) must be loaded in the current result before calling the function.
- The other input is the operands of 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      IN
