dnp3_header_block

Type: event (c: connection, is_orig: bool, len: count, ctrl: count, dest_addr: count, src_addr: count)

Generated for an additional header that the DNP3 analyzer passes to the script-level. This header mimics the DNP3 transport-layer yet is only passed once for each sequence of DNP3 records (which are otherwise reassembled and treated as a single entity).

Parameters

c – The connection the DNP3 communication is part of.
is_orig – True if this reflects originator-side activity.
len – the “length” field in the DNP3 Pseudo Link Layer.
ctrl – the “control” field in the DNP3 Pseudo Link Layer.
dest_addr – the “destination” field in the DNP3 Pseudo Link Layer.
src_addr – the “source” field in the DNP3 Pseudo Link Layer.

dnp3_object_header

Type: event (c: connection, is_orig: bool, obj_type: count, qua_field: count, number: count, rf_low: count, rf_high: count)

Generated for the object header found in both DNP3 requests and responses.

Parameters

c – The connection the DNP3 communication is part of.
is_orig – True if this reflects originator-side activity.
obj_type – type of object, which is classified based on an 8-bit group number and an 8-bit variation number.
qua_field – qualifier field.
number – TODO.
rf_low – the structure of the range field depends on the qualified field. In some cases, the range field contains only one logic part, e.g., number of objects, so only rf_low contains useful values.
rf_high – in some cases, the range field contains two logic parts, e.g., start index and stop index, so rf_low contains the start index while rf_high contains the stop index.

dnp3_object_prefix

Type: event (c: connection, is_orig: bool, prefix_value: count)

Generated for the prefix before a DNP3 object. The structure and the meaning of the prefix are defined by the qualifier field.

Parameters

c – The connection the DNP3 communication is part of.
is_orig – True if this reflects originator-side activity.
prefix_value – The prefix.

dnp3_pcb

Type: event (c: connection, is_orig: bool, control_code: count, count8: count, on_time: count, off_time: count, status_code: count)

Generated for DNP3 objects with the group number 12 and variation number 2

Parameters: PCB – Pattern Control Block

dnp3_response_data_object

Type: event (c: connection, is_orig: bool, data_value: count)

Generated for a DNP3 “Response_Data_Object”. The “Response_Data_Object” contains two parts: object prefix and object data. In most cases, object data are defined by new record types. But in a few cases, object data are directly basic types, such as int16_t, or int8_t; thus we use an additional data_value to record the values of those object data.

Parameters

c – The connection the DNP3 communication is part of.
is_orig – True if this reflects originator-side activity.
data_value – The value for those objects that carry their information here directly.
