Explanation of function and operation
1) This function performs division (
and outputs the operation result expressed as time data to devices specified in
2) The contents of 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.
Error
1) An operation error occurs when the divisor stored in devices specified in
not executed.
2) An operation error occurs when the operation result exceeds "2,147,483,647".
