TIME DATA FUNCTIONS

These functions output the sum of input values (TIME data) ((s1) + (s2)).

Operation processing
• These functions add the TIME type data input to (s1) and (s2) ((s1) + (s2)), and output the operation result from (d) as TIME
type data.
Ex.
When a value input to (s1) and (s2) is T#1d2h33m44s55ms (1 day 2 hours 33 minutes 44 seconds 55 milliseconds) and
T#2ms (2 milliseconds)
• A value input to (s1) and (s2) is the TIME type data value.
• Even if underflow or overflow occurs in the operation result, it is not regarded as an operation error. The data is output from
(d) as follows: "ADD_TIME_E" outputs "TRUE" from the output variable ENO.
Ex.
Overflow
The most significant bit becomes 1, and a negative time is output.
Ex.
Underflow
The most significant bit becomes 0, and a positive time is output.
