FUNCTION_BLOCK BELIMO_EPXXXX_FW_3_0_8_MOD

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 other registers may be written in that telegram. Format of 32-bit data points: Register+0 (LSW): H-byte L-byte Register+1 (MSW): H-byte L-byte\

FC02 may only be used for register 105 (Malfunction and service information, start address = 1664). | | Use the address values for addressing, not the register addresses. | | For unused registers the value 65535 (dec.) is read/written | | Modbus addresses 1 - 247 can be set directly on the valve. | | All writable register addresses > 100 are persistent and must not be written cyclically |
