Statistic
Description
Application Messages Tx
The number of application DNP3 packets sent by the module.
Application Messages Rx
The number of application DNP3 packets received by the
module.
Critical Messages Tx
The number of critical DNP3 packets sent by the module when
security is enabled.
Critical Messages Rx
The number of critical DNP3 packets received by the module
when security is enabled.
Messages Discarded
The number of DNP3 packets discarded by the module.
Error Messages Tx
The number of error DNP3 packets sent by the module.
Error Messages Rx
The number of error DNP3 packets received by the module.
Checksum errors
The number of corrupted DNP3 packets received by the
module.
Timeouts
The number of message response timeouts the module has
encountered.
Parity errors
The number of bytes with parity errors received by the module.
DNP3 Request Data Too Large
The request/response data is too big. The Hart 4 module allows
for a maximum of 1000 bytes per transaction.
DNP3 Request Out of Range –
Low
The DNP3 request has a range that is outside of the
implemented DNP3 bounds for the specific group and variation.
This error is specific to the range being lower than the
implemented range.
DNP3 Request Out of Range –
High
The DNP3 request has a range that is outside of the
implemented DNP3 bounds for the specific group and variation.
This error is specific to the range being higher than the
implemented range.
