MicroLogix 1400 Distributed Network Protocol (DNP3) Appendix F
For Small BCD type data, you can configure Class information in the
Configuration file. The lower 2 bits in each element of the Configuration files are
the configuration of Class information to the relevant objects. P0 bit in the first
element is for excluding Small BCD Data from Class 0 poll responses. Other bits
are reserved.

• Small BCD Config File Number
DNP3 Binary Input Object
The supported object group and variations are listed in this section. The
MicroLogix 1400 responds with the default group and variation when the DNP3
Master requests to read the object with all variations.
