Explanation of function and operation
This function converts string data (6 words) stored in a device specified in
data, and outputs the data obtained by conversion to a device specified in
1st word
String
2nd word
3rd word
4th word
5th word
6th word
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.
