Functionality
The block adds the time value entered at input IN2 to the time value entered at input IN1 (= IN1 + IN2). The block returns the result of this addition in format TIME.
No check of invalid connections
For some blocks, invalid connections are not checked by logi.CAD 3. 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 or →underflows might occur during a calculation using ADD_TIME. As your used →target system might influence the usage of →time literals in logi.CAD 3 (see "Properties and restrictions specific to the target system"), an overflow/underflow might occur for different return values when using different target systems.

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 .
FUNCTION_BLOCK ExampleAddTime VAR result : TIME; END_VAR result := ADD_TIME(IN1 := TIME#3s, IN2 := TIME#4s); Assert(result = TIME#7s);END_FUNCTION_BLOCKWhen creating your application within the ST-editor, enter a call of a block by typing the text as requested by the syntax or use Content Assist.
