CAN_setTripleSampling block

Short summary

Name	`CAN_setTripleSampling`
→POU type	→function
Category	more system blocks, Blocks for CAN , block with internal error diagnostic
Graphical interface
Available since	version 1.111.0 (for Neuron Power Engineer) and version 3.19.0 of Neuron RTS max This block is supported for →phyBOARD-Regor, →phyBOARD-Wega and →µMIC.200.

Functionality

The block sets triple sampling on the CAN interface (normal/FD).

Inputs, outputs

	Identifier	→Data type	Description
Inputs:	`HANDLE`	`DINT`	handle of the CAN interface (with initial value `-1`)
	`TRIPLESAMPLING`	`CAN_TRIPLESAMPLING_VALUE`	triple sampling is used (`ON`) or not (`OFF`), as specified in data type `CAN_TRIPLESAMPLING_VALUE` by the appropriate values
Outputs:	`RC`	`CAN_RETURN_CODE`	return code of the block call as specified in data type `CAN_RETURN_CODE` with the following values: `CAN_OK`, `CAN_SYSTEM_SERVICE_NOT_LOADED`, `CAN_NO_VALID_HANDLE`, `CAN_INTERFACE_SLOT_UNUSED`, `CAN_NOT_IMPLEMENTED`

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 value FALSE (or an equivalent): The return code of the block has not been 0 (see the above table under RC).

Example for usage within ST-editor

Best practice in order to get to know the usage of the CAN blocks: Create a new project based on the project template Simple Neuron Power Engineer CANopen Project for PHYTEC phyBOARD-Regor and study this sample project. This project contains a usage of this block.
