Offset Variable Name Description
12 14 DNP Slave Binary Input
Event count This value contains the total number of binary
input events which have occurred.
13 15 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.
14 16 DNP Slave Analog Input
Event count This value contains the total number of analog
input events which have occurred.
15 17 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.
16 18 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.
17 19 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.
18 20 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.
19 21 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.
20 22 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.
21 23 Total blocks transferred Total BTR/BTW or side-connect interface
transfers attempted by the module.
22 24 Successful blocks
transferred This value represents the total number of
transfer operations between the CompactLogix
processor and module that are successful.
23 25 Total errors in block
transfer Total number of transfers that resulted in an
error condition.
24 26 Total BTR or write errors Total number of BTR or write transfers that
resulted in an error.
25 27 Total BTW or read errors Total number of BTW or read transfers that
resulted in an error.
26 28 Block number error Number of BTW requests that resulted in an
incorrect BTW identification code.
27 29 Continuous block error
counter Count of sequential data transfer errors. When
this value exceeds that specified for the data
transfer operation, the error flag below will be
set.
28 30 Reserved Not used
29 31 Configuration Type This is a coded field that defines the
configuration of the module. The codes are as
follows: 0=Single Slave Configuration, 1=Dual
Slave Configuration, 2=Slave/Master
