Short summary

Name	`ArduinoDigitalWrite`
→POU type	→function
Category	Arduino functions, block with internal error diagnostic
Graphical interface
Available since	version 1.108.0 (for logi.CAD 3) This block is supported for →Arduino Nano and →Controllino of all sizes.

Functionality

The block writes a value to a specified pin.

Inputs

	Identifier	→Data type	Description
Inputs:	`pin`	`USINT`	Arduino pin number
Inputs:	`value`	`ArduinoDigitalPinValue`	value to write to the pin as defined in data type `ArduinoDigitalPinValue`

Input EN and output ENO are available when →calling the block. See "Execution control: EN, ENO" for information on input EN and output ENO.

See:

"Blocks for safe logic" whether this block is supported for developing safety-relevant applications.
"Highlighting safe logic in the FBD-editor" for the effects when using the block as a block for safe logic .

Internal error diagnostic for block

The block checks whether the specified pin is existing. If not, the output ENO of the block is set to value FALSE (or an equivalent).

Example for usage within ST-editor

Best practice in order to get to know the usage of the Arduino functions: Create a new project based on the project template for Controllino (e.g. Moving light for Controllino MAXI Automation) or for Arduino Nano and study this sample project.
