For MicroLogix 1400 Series B and Series C controllers:
Each of the data files for a DNP3 Object will have a file number in the user
memory as shown below. You can configure the Data file number for each
DNP3 Object in the DNP3 Slave tab of the DNP3 Slave Application Layer
Configuration. File types for this object file can be Binary, Integer, Long, or
Float data files.
The file numbers for each DNP3 Object cannot be in conflict with each other.
