Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling string data and 32-bit data in structured programs, you cannot specify 16-bit devices
directly, different from simple projects. Use labels when handling string data and 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 in the following case. The error flag M8067 turns ON, and D8067 stores the error
code.
1) When the number of points occupied by the string data storage destination (device specified in )
exceeds the range of the corresponding device
(Error code: K6706)
Program example
In this program, double word [signed] data stored in a device specified in is converted into string data,
and the data obtained by conversion is output to a device specified in .
1) Function without EN/ENO(DINT_TO_STR)
2) Function with EN/ENO(DINT_TO_STR_E)
