Master device#
IEC101 master device configuration is specified by
hat-gateway://iec101.yaml#/definitions/master.
According to gateway specification, all IEC101 master device event types have prefix:
'gateway', <gateway_name>, 'iec101_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)
iec101 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 iec101 messages
change of connection state
messages with test flag are ignored
time sync loop for each enabled remote device
Gateway events#
Events registered by gateway have event type starting with:
'gateway', <gateway_name>, 'iec101_master', <device_name>, 'gateway', ...
Available gateway events are:
…, ‘status’
Represents change in serial endpoint status. Upon enabling device, new
CONNECTINGstatus should be registered, andCONNECTEDonce serial endpoint is opened. Once device is disabled,DISCONNECTEDstatus should be assumed regardless of last registered status event (registration ofDISCONNECTEDstatus event during device disabling is mandatory but should not be relied upon).Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/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
CONNECTINGstatus should be registered. Once device is disabled or remote device is disabled,DISCONNECTEDstatus should be assumed regardless of last registered status event (registration ofDISCONNECTEDstatus 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://iec101.yaml#/definitions/events/master/gateway/status.…, ‘remote_device’, <device_address>, ‘data’, <data_type>, <asdu_address>, <io_address>
Represents received IEC101 data message.
Source timestamp is dependent on existence of IEC101 time. If IEC101 time is not available, source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/gateway/data.…, ‘remote_device’, <device_address>, ‘command’, <command_type>, <asdu_address>, <io_address>

Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/gateway/command.…, ‘remote_device’, <device_address>, ‘interrogation’, <asdu_address>
Represents received IEC101 interrogation message.
Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/gateway/interrogation.…, ‘remote_device’, <device_address>, ‘counter_interrogation’, <asdu_address>
Represents received IEC101 counter interrogation message.
Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/gateway/counter_interrogation.
System events#
Events registered by other Hat components, which are consumed by gateway, have event type starting with:
'gateway', <gateway_name>, 'iec101_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://iec101.yaml#/definitions/events/master/system/enable.…, ‘remote_device’, <device_address>, ‘command’, <command_type>, <asdu_address>, <io_address>
Represents request for command execution.
Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/system/command.…, ‘remote_device’, <device_address>, ‘interrogation’, <asdu_address>
Represents request for interrogation (interrogation activation).
Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/system/interrogation.…, ‘remote_device’, <device_address>, ‘counter_interrogation’, <asdu_address>
Represents request for counter interrogation (interrogation activation).
Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/master/system/counter_interrogation.
Slave device#
IEC101 slave device configuration is specified by
hat-gateway://iec101.yaml#/definitions/slave.
According to gateway specification, all IEC101 slave device event types have prefix:
'gateway', <gateway_name>, 'iec101_slave', <device_name>, <source>, ...
IEC101 slave device provides implementation of IEC101 slave which accepts multiple parallel remote master connections, one for each configured device address. Change of active master connections list is trigger for registration of new gateway ‘connection’ event containing current list’s state.
IEC101 slave device is configured with list of available data. Once device is enabled, device will query last system ‘data’ events corresponding to configured data. This local cache is continuously updated with latest data states based on received system ‘data’ events. All remote masters are notified with IEC101 data messages each time locally cached data state is changed. When slave receives IEC101 interrogation or counter interrogation message, it will immediately respond with IEC101 interrogation/data messages based on current state of local data cache. Interrogation deactivation is not supported (slave responds with negative confirmation).
In addition to local cache of last data states, IEC101 slave device can be configured with arbitrary number of circular data buffers, each configured with limited size. Each data can be associated with single buffer. When system ‘data’ event, associated with configured data, is received, together with local cache update, data change is appended to the end of configured data buffer. Once buffer is full, new changes will overwrite oldest changes. Data change is removed from buffer when at least one remote master is notified with data change (slave sends data poll response with data change). When remote master connect to slave and new connection is established, slave will immediately schedule sending of IEC101 data messages for each buffered data change. Slave’s initial query of system ‘data’ events is not buffered.
In addition to sending IEC101 data messages and processing IEC101 interrogation and counter interrogation requests, slave supports IEC101 command messages. Command messages are transparently bidirectionally mapped to ‘command’ events. Each time slave receives IEC101 command request, it will register new gateway ‘command’ event which contains unique identification of master connection which sent command request. When new system ‘command’ event is received, it must contain identification of master connection which will be used for sending associated IEC101 command response.
Gateway events#
Events registered by gateway have event type starting with:
'gateway', <gateway_name>, 'iec101_slave', <device_name>, 'gateway', ...
Available gateway events are:
…, ‘connections’
Represents change in list of all active connections. When device is disabled, empty list of connections is assumed (when device is disabled, new connections event should be registered but user should not depend on this behaviour).
Source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/slave/gateway/connections.…, ‘command’, <command_type>, <asdu_address>, <io_address>
Represents received IEC101 command message.
Source timestamp is dependent on existence of IEC101 time. If IEC101 time is not available, source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/slave/gateway/command.
System events#
Events registered by other Hat components, which are consumed by gateway, have event type starting with:
'gateway', <gateway_name>, 'iec101_slave', <device_name>, 'system', ...
Available system events are:
…, ‘data’, <data_type>, <asdu_address>, <io_address>
Represents data change.
Source timestamp is dependent on existence of IEC101 time. If IEC101 time is not available, source timestamp is
None.Payload is specified by
hat-gateway://iec101.yaml#/definitions/events/slave/system/data.…, ‘command’, <command_type>, <asdu_address>, <io_address>
Represents command response.
Source timestamp is dependent on existence of IEC101 time. If IEC101 time is not available, source timestamp is
None.Payload is specified by
