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
An operation error occurs when this function is executed in the following setting status. The error flag M8067
turns ON, and D8067 stores the error code K6706.
Contents of a device specified in > Contents of a device specified in
(Lower limit data) (Upper limit data)
Program example
In this program, data whose type is same as the data stored in devices specified in , and is
output to a device specified in in accordance with ANY_SIMPLE type data stored in devices specified in
