Table 5-2: Modbus Address Mapping
For example:
To enable the heating of water, a write request must be sent to the
address for the
“Remote Heater Power” coil with a value of 1.
To disable the heating of water, a write request must be sent to the
address for the
“Remote Heater Power” coil with a value of 0.
To monitor the temperature set point, a read request must be sent to
the address for the
“Remote Set Point” register.
To adjust the temperature set point, a write request must be sent to
the address for the
“Remote Set Point” register with a value between
15 and 95.
