Integrations
Modbus TCP and RTU
Configure Modbus field communication with target-aware validation and commissioning checks.
Nodectra models Modbus through Connection → Device → Point.
Modbus TCP
Configure the network endpoint, timeout and polling behavior on the Connection. Configure unit/device address on the Device and register details on each Point.
Modbus RTU
RTU uses a physical serial interface, commonly isolated RS-485. Configure port, baud rate, parity, data bits and stop bits according to the complete bus. The target hardware profile must expose the requested serial capability.
Commissioning checklist
- verify bus polarity, termination, bias and common reference;
- ensure unique device addresses;
- confirm register base convention and function code;
- verify word/byte order for multi-register values;
- validate scaling, unit and writable range;
- test offline and recovery quality behavior;
- prove actuator writes with safe field supervision.
