Detailed Description

Outstation configuration.

Field Documentation

class_zero

dnp3_class_zero_config_t dnp3_outstation_config_t::class_zero

Controls responses to Class 0 reads.

confirm_timeout

uint64_t dnp3_outstation_config_t::confirm_timeout

Confirmation timeout.

Note

The unit is milliseconds

decode_level

dnp3_decode_level_t dnp3_outstation_config_t::decode_level

Decoding level.

event_buffer_config

dnp3_event_buffer_config_t dnp3_outstation_config_t::event_buffer_config

Event buffer sizes configuration.

features

dnp3_outstation_features_t dnp3_outstation_config_t::features

Optional features.

keep_alive_timeout

uint64_t dnp3_outstation_config_t::keep_alive_timeout

Delay of inactivity before sending a REQUEST_LINK_STATUS to the master.

A value of zero means no automatic keep-alive will be sent.

Note

The unit is milliseconds

master_address

uint16_t dnp3_outstation_config_t::master_address

Link-layer master address.

max_controls_per_request

uint16_t dnp3_outstation_config_t::max_controls_per_request

Maximum number of controls in a single request.

max_read_request_headers

uint16_t dnp3_outstation_config_t::max_read_request_headers

Limits the selections or headers processed in a READ request.

Internally, this controls the size of pre-allocated buffers used to process requests. A minimum value of 64 is always enforced.

A READ processed right away counts only the static selections it makes: one per static header that selects points, and one per class 0 type that has points. Event headers, and headers that select nothing, don't count. A READ that arrives while the outstation waits for an unsolicited confirm is held as pending, and holding it counts each header that parses, event headers included.

Past the limit, further selections or headers are ignored, the rest are answered, and the response sets the PARAMETER_ERROR IIN bit. Device attributes (group 0) have a separate, fixed limit of 32 selections per READ.

Independent of this limit, a READ whose selection visits more points, events or attribute sets than a fixed multiple of the database is answered with PARAMETER_ERROR and no objects.

max_unsolicited_retries

uint32_t dnp3_outstation_config_t::max_unsolicited_retries

Maximum number of unsolicited retries.

outstation_address

uint16_t dnp3_outstation_config_t::outstation_address

Link-layer outstation address.

rx_buffer_size

uint16_t dnp3_outstation_config_t::rx_buffer_size

Receive buffer size.

Must be at least 249 bytes

select_timeout

uint64_t dnp3_outstation_config_t::select_timeout

Select timeout.

Note

The unit is milliseconds

solicited_buffer_size

uint16_t dnp3_outstation_config_t::solicited_buffer_size

Solicited response buffer size.

Must be at least 249 bytes

unsolicited_buffer_size

uint16_t dnp3_outstation_config_t::unsolicited_buffer_size

Unsolicited response buffer size.

Must be at least 249 bytes

unsolicited_retry_delay

uint64_t dnp3_outstation_config_t::unsolicited_retry_delay

Delay to wait before retrying an unsolicited response.

Note

The unit is milliseconds
