Compatible with the controls a plant already runs.
OPC UA servers, Modbus meters and controllers, and EtherCAT drives are read where they are. Each adapter is observe-only: it decodes, signs and hands readings to the interface, and has no way to write back. Standards and vendor names describe what is compatible; they are not endorsements.
Controllers, drives and meters.
Each connection is read-only until a person approves otherwise, and every reading is signed and graded before the interface admits it.
Controller variables browsed, read and subscribed.
SupportedMeter, drive and controller registers read, over TCP and decoded from RTU traces.
SupportedDrive process data tapped passively.
SupportedData path, mechanism, trust path.
What goes in, how the adapter reads it, and why it can be trusted.
OPC UA · industrial serverSupported
- Data path
- Variables of a controller's information model, in.
- Mechanism
- The adapter browses, reads and subscribes. It never writes and never calls a method. Run against an independent OPC UA server.
- Trust path
- Readings are signed at the node, graded by the weakest link, and admitted into the twin only inside its solved band. Commands leave only through the command gate, after the purpose check and, where the level requires it, a person's approval.
Modbus · register deviceSupported
- Data path
- Registers and coils of meters, drives and controllers, in.
- Mechanism
- Read functions only. Modbus TCP run against a live server where every request received was a read; RTU is decoded from traces.
- Trust path
- Readings are signed at the node, graded by the weakest link, and admitted into the twin only inside its solved band. Commands leave only through the command gate, after the purpose check and, where the level requires it, a person's approval.
EtherCAT · motion busSupported
- Data path
- Process data of the drives on a segment, in.
- Mechanism
- A passive tap reads drive-profile measured values and status words and sends nothing back. Run on a virtual link carrying the frames of a classic capture.
- Trust path
- Readings are signed at the node, graded by the weakest link, and admitted into the twin only inside its solved band. Commands leave only through the command gate, after the purpose check and, where the level requires it, a person's approval.
Out of the plant: variables, registers and process data. Into the interface: signed, graded readings admitted inside the twin's band.
Reads only. The OPC UA adapter never writes or calls a method; the EtherCAT tap sends nothing; Modbus uses read functions only.
Commands to a controller leave only through the command gate, with the purpose check and a person's approval.
