Processing details
■
Operation processing
• These functions perform multiplication between the TIME data type values input to (s1) and (s2) ((s1)

(s2)), and output the
operation result, in the TIME data type, from (d).
Ex.
When (s1)=T#1d2h33m44s55ms (1 day, 2 hours, 33 minutes, 44 seconds, 55 milliseconds) and (s2)=2
• Input a TIME data type value to (s1).
• Input an INT, DINT, REAL, or LREAL data type value to (s2).
• Even if an underflow or overflow occurs in the operation result, no operation error is issued. The following is output to (d).
When MUL_TIME_E is used, ENO outputs TRUE. (In this case, the output value is of TIME data type with the upper 32 bits
deleted although the operation result is 64-bit data.)
Ex.
Overflow
A negative time value results because the most significant bit is 1.
Ex.
Underflow
A positive time value results because the most significant bit is 0.
■
Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
• When (s2) is of LREAL data type
Execution condition Operation result
EN ENO (d)
TRUE (executed) TRUE Operation result output value
FALSE (not executed) FALSE
*1
Undefined value
