FXCPU Structured Programming Manual

5.9.3 MUL_TIME(_E)
Outline
This function performs multiplication of time data.
1. Format
*1. Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function performs multiplication( × ) using time data stored in devices specified in and
, and outputs the operation result expressed as time data to devices specified in .
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different
from simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
3) Even if underflow or overflow occurs in the operation result, it is not regarded as an operation error.
However, note that the accurate operation result cannot be obtained in this case.
("MUL_TIME_E" outputs "TRUE" from ENO.)
