Processing details
■Operation processing
• Performs multiplication ((s1)  (s2)) on time type data input to (s1) and the word (signed), double word (signed), single-
precision real or double-precision real type data input to (s2), and outputs the operation result from (d) in time type.
Ex.
When the input value to (s1) and (s2) are T#1d2h33m44s55ms (1 day 2 hours 33 minutes 44 seconds 55 milliseconds) and
2.
s1
T#1d2h33m44s55ms
Time type Word (signed)
• The value to be input to (s1) is time type data.
• The value to be input to (s2) is word (signed), double word (signed), single-precision real or double-precision real type data.
• Rounding error may occur when specifying single-precision real or double-precision real type data to (s2) by programming
tool.
For precautions when setting an input value using a programming tool, refer to the following.
 MELSEC-Q/L/F Structured Programming Manual (Fundamentals)
No operation error occurs even if an underflow/overflow occurs. Data is output from (d) as follows. In case of MUL_TIME_E,
TRUE is output from ENO. (Although the operation result is 64-bit data, data is output in time type with the high-order 32 bits
discarded.)
Ex.
Overflow
T#24d20h31m23s647ms
(7FFFFFFF ) (00000002
H
Since the highest-order bit is 1, the result value is negative.
