Chapter 6 Micro870 Controller Distributed Network Protocol
Some of objects are divided into several Object files to map data in the controller.
• Counter Object — 16-bit and 32-bit Counter Object
• Analog Input Object — 16-bit and 32-bit Analog Input Object, and Short Floating Point
Analog Input Object.
• Analog Output Object — 16-bit and 32-bit Analog Output Object, and Short Floating Point
Analog Output Object.
DNP3 Mapping for Micro870 controllers
You can create the different data objects by mapping them to the variables created in the
controller. You can configure the Data object for each DNP3 Object in the DNP3 Slave
configuration page. Variables can be BOOL, INT, DINT, or REAL data types.
