ioBroker IEC 60870-5-104 Adapter

ioBroker adapter for IEC 60870-5-104 master and slave communication.

The adapter can run as an IEC-104 master or slave. Received points are grouped by ASDU/common address below ASDU-<address>. Each ASDU contains separate folders for values, IV quality, NT quality, timestamps and COT information.

Features

• Master mode for connecting to an IEC-104 controlled station.
• Slave mode for exposing configured ioBroker states over IEC-104.
• General interrogation after connect and optional cyclic interrogation.
• Configurable COT, common address and IOA field sizes.
• Configurable data point table with import and export support.
• State layout grouped by ASDU/common address.
• Separate states for value, IV, NT, timestamp and COT text.

Configuration

Set the connection mode first:

• Master / controlling station: connects to a remote IEC-104 slave.
• Slave / controlled station: listens locally for a remote IEC-104 master.

Common settings:

| Setting | Meaning | | --- | --- | | Remote host | Remote host used in master mode. | | TCP port | IEC-104 TCP port, usually 2404. | | Bind address | Local bind address used in slave mode. | | Common address | Default common address for configured points. | | Originator address | Originator address used in ASDUs. | | Read only | Reject command ASDUs from the remote side. |

Data Points

Configured points define how IEC-104 IOAs are mapped to ioBroker states. The table supports monitoring types, command types, timestamps, scaling and optional per-point common addresses.

The adapter also stores received points below ASDU-<address> so values from different common addresses remain separated.
