3.2.3 DNPSlave_Err Object

The DNPSlave_Err object stores the slave status information returned from the

module after a 9949-block request from the ladder logic. An array of this object

should be defined to hold the status data for each slave used by the module. The

structure of the object is displayed in the following example:

Tag Name Data Type Description

Device_Index INT Index in the slave array for the master port

Slave_ID INT Slave address for device

Err_CRC INT Number of CRC errors

Err_Overflow INT Number of overflow errors

Err_Seq INT Number of sequence errors

Err_DLConf INT Number of data-link confirm retry errors

Err_DLCFail INT Number of data-link confirm failures

Err_AppResp INT Number of application response errors

3.2.4 DNP_BI_Event Object

The DNP_BI_Event object stores the information for a single binary input event

to be sent from the processor to the module in a command block 9958. The

structure shown contains all the parameters required for a binary input event.

Tag Name Data Type Description

EventCount INT Event Count

SeqCounter INT Sequence Counter

BinInptDataPt INT DNP Binary Input Data Point

MonDayState INT Month/Day/State

HourMin INT Hour/Minute

SecMilsec INT Second Millisecond

Year INT Year

Event2 INT[5] Event #2

Event3 INT[5] Event #3

Event4 INT[5] Event #4

Event5 INT[5] Event #5

Event6 INT[5] Event #6

Event7 INT[5] Event #7

Event8 INT[5] Event #8

Event9 INT[5] Event #9

Event10 INT[5] Event #10

Event11 INT[5] Event #11

3.2.5 DNP_AI_Event Object

The DNP_AI_Event object stores the information for a single analog input event

to be sent from the processor to the module in a command block 9959. The

structure shown contains all the parameters required for an analog input event.

Tag Name Data Type Description

EventCount INT Event Count

SeqCounter INT Sequence Counter

AIDataPt INT DNP Analog Input Data Point
