BELIMO_EVXXX_RX_FW_4_0_UND_4_1_MOD

BELIMO_EVXXX_RX_FW_4_0_AND_4_1_MOD (FB)

FUNCTION_BLOCK BELIMO_EVXXX_RX_FW_4_0_AND_4_1_MOD

Representation

Guidelines - software creation

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

For write operations on 32-bit data points (2 consecutive Modbus registers), FC16 must be used. No further registers may 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 (dec.) is read/written.

  • The calibration of the temperature sensors must be performed in the device; however, no adjustment is possible via Modbus.

  • 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 device firmware cannot currently (06.09.2024) be read from address 103. The value 0 is always read.

  • Measured values - adjustment: Class ???
