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

The 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 (dec.) is read / written. | | The calibration of the temperature sensors must be carried out in the device; however, no adjustment is possible via Modbus. | | The Modbus addresses 1 - 247 can be set directly in the integrated web server. | | All writable register addresses > 100 are persistent and must not be written cyclically | | The firmware of the device can currently (06.09.2024) not be read from address 103. The value 0 is always read. | | | Notes on the input rRelSetp (Relative setpoint - position/flow rate/power in % (0.0 - 100.0 %)) | | | 1) The function 'Flow rate depending on the signal rRelSetp' is not linear !!! (See Belimo documentation) | 2) The specification of an absolute flow rate setpoint can therefore be made as follows: | | a) External PI controller (inverted, 0 - 100 percent): Actual value = rAbsVolFlowUnit, setpoint = desired absolute setpoint, connect actuating signal to input rRelSetp . | b) Assign constant 100.0 to input rRelSetp , write parameter rMaxAbsVolFlowUnit with the desired absolute setpoint | Attention: Parameter rMaxAbsVolFlowUnit must not be written cyclically !!! | | Measured values - adjustment: Class ??? |
