The RTD-10 supports the same Modbus command set as the RTD-NET interface (see attached RTD-NET Installation Instructions in this article). The register base is '0'.
- Please take note of the listed Modbus function codes to read and write to Holding and Input registers.
- Note that Holding Registers are read/write registers that are used for control parameters. These are used to control, but also monitoring (e.g. fan speed, mode etc.)
- Note that when using our free software ModTool (ModTool Communication with our Products) all available Modbus registers can be found using the procedure described in ModTool-article->How to use->Further data
Please note that if the RTD-10 is operated in Duty/Standby mode monitoring via Modbus only is possible if a Modbus gateways is used (we recommend our interface RTD-DSX).
