ADD_LDT_LTIME

Type	Function
Description	Adds the duration (LTIME) connected to IN2 to the point in time (LDATE_AND_TIME) connected to IN1 and writes the result (LDATE_AND_TIME) to the output.
Notes	When the addition result exceeds the permissible range of the output value, an overflow occurs. The function provides implicit data type conversion at its input and output parameters according to the rules defined by the IEC 61131 standard.
Parameters	Inputs IN1 Data type: LDATE_AND_TIME Description: Point in time to which the duration at IN2 is added. IN2 Data type: LTIME Description: Duration to add. Output Out Data type: LDATE_AND_TIME Description: Result point in time.
Error behavior	Error behavior The following table shows the errors which may occur while executing the function and the value returned by the function in the corresponding error case. Error case Output value Overflow Overflow value
Additional information	EN/ENO behavior The POU is only executed if TRUE is applied to the EN input. If EN = FALSE, the POU is not executed and ENO = FALSE indicates the inactivity. If any of the errors listed under "Error behavior" occurs while executing the function, ENO is set to FALSE. Further Info See the topic "General information on execution control with EN/ENO" for further details.
