Word Variable Name Description
20 DNP Slave user data
overflow error (Transport
Layer Error) This value counts the number of times the application
layer receives a message fragment buffer which is too
small.
21 DNP Slave sequence error
(Transport Layer Error) This value counts the number of times the sequence
numbers of multi-frame request fragments do not
increment correctly.
22 DNP Slave address error
(Transport Layer Error) This value counts the number of times the source
addresses contained in a multi-frame request fragments
do not match.
23 DNP Slave Binary Input
Event count This value contains the total number of binary input
events which have occurred.
24 DNP Slave Binary Input
Event count in buffer This value represents the number of binary input events
which are waiting to be sent to the master.
25 DNP Slave Analog Input
Event count This value contains the total number of analog input
events which have occurred.
26 DNP Slave Analog Input
Event count in buffer This value represents the number of analog input events
which are waiting to be sent to the master.
27 DNP Slave Float Input
Event count in buffer This value represents the number of float input events
which are waiting to be sent to the master.
28 Reserved Future Use
29 DNP Slave bad function
code error (Application
Layer Error) This value counts the number of times a bad function
code for a selected object/variation is received by the
slave device.
30 DNP Slave object unknown
error (Application Layer
Error) This value counts the number of times a request for an
unsupported object is received by the slave device.
31 DNP Slave out of range
error (Application Layer
Error) This value counts the number of times a parameter in the
qualifier, range or data field is not valid or out of range.
32 DNP Slave message
overflow error (Application
Layer Error) This value counts the number of times an application
response message from the slave is too long to transmit.
33 DNP Slave multi-frame
message from DNP Master
error (Application Layer
Error) This value counts the number of times the slave receives
a multi-frame message from the master. The application
does not support multi-frame master messages.
34 UDP Receive Count Number of UDP messages received
35 UDP Transmit Count Number of UDP messages transmitted
36 Unsolicited Error Count Number of failures when trying to send unsolicited event
data
37 State Value This variable has a value of 0 if there is not a message
being sent and 1 if a message is being sent.
38 TCP Socket State Value State machine value for the TCP socket
39 UDP Socket State Value State machine value for the UDP socket
40 DNP Busy With Message
State Socket busy state -1=TCP socket not connected, 0=TCP
or UDP not processing message, 1 or 3 = TCP
processing message, and 2=UDP socket processing
message.
41 Application Fragment Application fragmentation flag/counter
