MUL_TIME block

Short summary

Name	`MUL_TIME`
→POU type	→function
Category	IEC-block, Time
Conform to →IEC-standard	currently restricted (IEC demands error handling, if the result of the block exceeds the range of values for the output data type. See "No check of invalid connections" for the behavior in Neuron Power Engineer.)
Graphical interface
Available since	version 1.0.0 (for Neuron Power Engineer)

Functionality

The block multiplies the time value entered at input IN1 by a numerical value entered at input IN2 (= IN1 * IN2). The block returns the product of this multiplication in format TIME.

No check of invalid connections

For some blocks, invalid connections are not checked by Neuron Power Engineer. Therefore, enter code in your application to detect invalid connections (e.g. IF-statements in the ST-code).

See "IEC-blocks for the application" for information what the consequences of an invalid connection might be.

An invalid connection due to →overflows might occur during a calculation using MUL_TIME. As your used →target system might influence the usage of →time literals in Neuron Power Engineer (see "Properties and restrictions specific to the target system"), an overflow might occur for different return values when using different target systems.

Inputs, return value

	Identifier	→Data type	Description
Inputs:	`IN1`	`TIME`	time value
Inputs:	`IN2`	`REAL`, `LREAL`, `USINT`, `UINT`, `UDINT`, `ULINT`, `SINT`, `INT`, `DINT` or `LINT` (corresponds to →generic data type `ANY_NUM`)	numerical value
Return value:	–	`TIME`

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.

Example for usage within ST-editor

The calculated values are evaluated by using the Assert block.

VAR

    product : TIME;

  END_VAR

  product := MUL_TIME(IN1 := T#1m40s, IN2 := 2.0);

  Assert(product = TIME#3m20s);
