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. - Converts a Binary Coded Decimal (BCD) value to a binary value.

Q	DINT			Converts a Binary Coded Decimal (BCD) value to a binary value. Value converted to integer or 0 (zero) if IN is not a valid positive Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. BCD value.

Description

DINT

Converts a Binary Coded Decimal (BCD) value to a binary value.

Value converted to integer or 0 (zero) if IN is not a valid positive Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. BCD value.

Remarks

The input must:
- Be positive.
- Represent a valid BCD value.

FBD Language Example

FFLD Language Example

In the 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.

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 - This is a method of drawing electrical logic schematics. It is 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
