→POU type	→function
Category	IEC-block, Safe-Convert

Functionality

The blocks serves for explicitly converting the DATE_AND_TIME value connected to input IN into a value of data type SAFEDT.

When using a safe convert block, you must make sure that the input signal to the safe convert block is suitable to be used as safe signal. Neuron Power Engineer does not ensure that a signal status is safe but only highlights safe logic in the FBD-editor so that you are able to differentiate beween safety-relevant and standard signals.

Inputs, return value

	Identifier	→Data type	Description
Inputs:	`IN`	`DATE_AND_TIME`	value to be converted
Return value:	–	`SAFEDT`

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.
