IEC 60870-5-103 devices

Together with IEC103 specific events, generic enable and running events are also supported.

Supported data types (<data_type>):

  • ‘double’

  • ‘m1_i_l2’

  • ‘m1_u_l12’

  • ‘m1_p’

  • ‘m1_q’

  • ‘m2_i_l1’

  • ‘m2_i_l2’

  • ‘m2_i_l3’

  • ‘m2_u_l1e’

  • ‘m2_u_l2e’

  • ‘m2_u_l3e’

  • ‘m2_p’

  • ‘m2_q’

  • ‘m2_f’

Master device

IEC103 master device configuration is specified by hat-gateway://iec103.yaml#/$defs/master.

According to gateway specification, all IEC103 master device event types have prefix:

'gateway', <gateway_name>, 'iec103_master', <device_name>, <source>, ...

Todo

  • create master loop (open serial endpoint) (serial port reconnect delay)

  • enable/disable remote device (query last state on enable device and listen for changes)

  • reconnect procedure when serial endpoint available and remote device is enabled (remote device reconnect delay)

  • iec103 messages are sent to device only as reaction to system events

  • only “automatic” driver action is reconnect loop

  • new gateway events are generated only as reaction to:
    • receiving iec103 messages

    • change of connection state

  • time sync loop for each enabled remote device

Gateway events

Events registered by gateway have event type starting with:

'gateway', <gateway_name>, 'iec103_master', <device_name>, 'gateway', ...

Available gateway events are:

  • …, ‘status’

    Represents change in serial endpoint status. Upon enabling device, new CONNECTING status should be registered, and CONNECTED once serial endpoint is opened. Once device is disabled, DISCONNECTED status should be assumed regardless of last registered status event (registration of DISCONNECTED status event during device disabling is mandatory but should not be relied upon).

    Source timestamp is None.

    Payload is specified by hat-gateway://iec103.yaml#/$defs/events/master/gateway/status.

  • …, ‘remote_device’, <device_address>, ‘status’

    Represents change in remote device connection status. Once serial endpoint is opened and remote device enabled, new CONNECTING status should be registered. Once device is disabled or remote device is disabled, DISCONNECTED status should be assumed regardless of last registered status event (registration of DISCONNECTED status event during device disabling or remote device disabling is mandatory but should not be relied upon).

    Source timestamp is None.

    Payload is specified by hat-gateway://iec103.yaml#/$defs/events/master/gateway/status.

  • …, ‘remote_device’, <device_address>, ‘data’, <data_type>, <asdu_address>, <io_function>, <io_information>

    Represents received IEC103 data message.

    Source timestamp represents IEC103 data time.

    Payload is specified by hat-gateway://iec103.yaml#/$defs/events/master/gateway/data.

  • …, ‘remote_device’, <device_address>, ‘command’, <asdu_address>, <io_function>, <io_information>

    Represents received IEC103 command message.

    Source timestamp is None.

    Payload is specified by hat-gateway://iec103.yaml#/$defs/events/master/gateway/command.

  • …, ‘remote_device’, <device_address>, ‘interrogation’, <asdu_address>

    Represents received IEC103 end of interrogation message.

    Source timestamp is None.

    Payload is None.

System events

Events registered by other Hat components, which are consumed by gateway, have event type starting with:

'gateway', <gateway_name>, 'iec103_master', <device_name>, 'system', ...

Available system events are:

  • …, ‘remote_device’, <device_address>, ‘enable’

    Represents request for enable/disable remote device.

    Source timestamp is None.

    Payload is specified by hat-gateway://iec103.yaml#/$defs/events/master/system/enable.

  • …, ‘remote_device’, <device_address>, ‘command’, <asdu_address>, <io_function>, <io_information>

    Represents request for command execution.

    Source timestamp is None.

    Payload is specified by hat-gateway://iec103.yaml#/$defs/events/master/system/command.

  • …, ‘remote_device’, <device_address>, ‘interrogation’, <asdu_address>

    Represents request for interrogation.

    Source timestamp is None.

    Payload is None.
