Representation

Guidelines - Software creation

The following function codes (FC) are supported: 3, 4 (additionally: 2, 4, 16)

For write operations to 32-bit data points (2 consecutive Modbus registers), FC16 must be used. No further registers may then be written in this telegram. Format of 32-bit data points: Register+0 (LSW): H-byte L-byte Register+1 (MSW): H-byte L-byte

FC 02 may only be used for register 105 (Malfunction and service information, start address = 1664). | | For addressing, the address specifications must be used, not the register addresses. | | For unused registers, the value 65535 (decimal) is read / written. | | Modbus addresses 1 - 247 can be set with the known Belimo tools. | | All writable register addresses > 100 are persistent and must not be written cyclically | | The device firmware cannot currently (06.09.2024) be read from address 103. The value 0 is always read. | | Measured values - matching: Class ??? | | There are no matching measurands available. |
