MicroLogix 1400 Distributed Network Protocol (DNP3) Appendix F
Data file types used in DNP3 Objects are not the same as that used in the
MicroLogix controller, but are similar. Mapping is required between DNP3 data
files and MicroLogix 1400 data files.
Overview
DNP3 Data objects that are implemented in the MicroLogix 1400 controller are
listed below:
• DNP3 Binary Input Object
• DNP3 Double Bit Binary Input Object
• DNP3 Binary Output Object
• DNP3 Counter Object
• DNP3 Frozen Counter Object
• DNP3 Analog Input Object
• DNP3 Analog Output Object
• DNP3 BCD Object
• DNP3 Data Set Object (Series B controllers only)
Some of objects are divided into several Object files to map data files in the
MicroLogix 1400 controller.
• Counter Object — 16bit and 32bit Counter Object File
• Analog Input Object — 16bit and 32bit Analog Input Object File, and
Short Floating Point Analog Input Object File.
• Analog Output Object — 16bit and 32bit Analog Output Object File,
and Short Floating Point Analog Output Object File.
