Appendix A.7. Internal Indications, Object 80 and DNP_II

The driver can store the Internal Indications Bits found in incoming messages and it is possible to control the values of the internal indication bytes sent in responses. In addition, the driver can be configured to respond to the Poll for Object 80 (Internal Indications)

A.7.1. Incoming Internal Indications Bytes

This driver can expose data from the most recently consumed message and additional diagnostic information using a special Map Descriptor called “DNP_ii” (DNP Internal Indications)

The following example shows the configuration of this Map Descriptor. Only one of these Map Descriptors may be configured per FieldServer.

The first byte of the Internal indication reported by a DNP device as found in the most

 

 

recently received message.

 

 

Only messages complete enough to warrant parsing will cause this item to be

updated.

 

 

 

DNP devices only contain internal indication bytes when the message is an application layer response type message. Typically this includes all responses to data queries/writes as well as unsolicited messages.

1The 2nd byte of the response internal indication.

Bit zero is the least significant bit.

A one (1) in the bit position indicates the described state.
