Appendix F MicroLogix 1400 Distributed Network Protocol
Basically, the index number of DNP objects of each type is evaluated by the
firmware automatically per the number of elements. For example, if a Binary
Input object file was configured as an element, the highest index number of
the Binary Input object is 15. The index number can only be increased by 16. If a
Double-bit Binary Input object file was configured as an element, the highest
index number of the Double-bit Binary Input object is 7. The index number can
only be increased by 8.
As another example, if a 16-bit Analog Input object file was configured as an
element, the highest index number is 1. Except for Binary and Double-bit
Binary type objects, the index number can be increased by 1.
DNP3 Configuration Files
You can set configuration files for each object. These configuration files allow
you to configure parameters such as Class level and Object Flag bit
information for each element. Only a Binary Data file type can be used for
configuration file.
