IEC 60870-5-104 | ioBroker

IEC 60870-5-104 master/slave adapter with general interrogation and configurable data points.

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.
