- On the description of the "Definition respective maximum numbers of items" section in the configuration file
- Versions Concerned

When executing the configuration file, the configurator continues outputting the "sys_rom.inc" file without terminating itself.

This problem occurs if either of the following conditions is satisfied:
| (1) |
For any of the object types listed below, the maximum number of it is not defined in the definition respective maximum numbers of items section (the maxdefine{ } section), and 33 or more objects of the same type as the above are defined in that object type's property definitions. |
| (2) |
For any of the object types listed below, the maximum number of it is defined in the definition respective maximum numbers of items section, and then a lot of objects of the same type as the above are defined in that object type's property definitions; at this time, the number of objects in the latter definition exceeds the maximum number in the former and is equal to 33 or greater. |
List of the Object Types Concerned

For every object type, define the maximum number of objects in the definition respective maximum numbers of items section so that it is not less than the number of objects of the same type defined in that object type's property definitions.
