Offset Variable Name Description
11 13 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.
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 PLC processor and
module that are successful.
23 25 Total errors in block transferTotal 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 Configuration
