Always observe the cautions before development to develop a program.
If the data transferred does not follow the file name rule, the NC will mistake it for
another data, resulting in unexpected operation, e.g. PLC program erasure.
Do not read a ladder file on which a conversion error occurred into the GX Developer
side. The file may include unexpected contents to result an illegal operation.
When an error occurred at GX Developer On-line function, the error message may not
explain exactly the state in the CNC controller side.
Always refer to the error list.
