GPIOWritePin block

Short summary

Name	GPIOWritePin
→POU type	→function
Category	more system blocks, Blocks for GPIOs, block with internal error diagnostic
Graphical interface
Available since	version 1.85.0 (for Neuron Power Engineer) and version 3.5.2 of Neuron RTS max This block is supported for →phyBOARD-Regor.

Functionality

The block writes the value of a GPIO output pin.

Inputs, outputs

	Identifier	→Data type	Description
Inputs:	port	USINT	0-based port index of the addressed GPIO
	pin	USINT	0-based pin index of the addressed GPIO
	pinValue	BOOL	the value that will be written TRUE: pin is set active FALSE: pin is set passive
Return value:	-	UDINT	the return code of the operation 0: OK 1: common error 3: System service not loaded

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 the following error cases and – if they occur – the block sets the output ENO of the block to the value FALSE (or an equivalent): The return code of the block is not 0 (see above).

Example for usage within ST-editor

At present, there is no example.
