FUNCTION_BLOCK BELIMO_EVXXXF_FW_3XX_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\

FC 02 may only be used for register 105 (Malfunction and service information, start address = 1664). | | For addressing, use the address values, not the register addresses. | | For unused registers the value 65535 (dec.) is read / written | | The calibration of the temperature sensors must be performed on 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 | | This function block can also be used for the EnergyValves EVXXX RX (in-line) with firmware 3.X !!! | For the EnergyValves EVXXX RX (in-line) with firmware 4.X there are separate function blocks. | | Measurements - Adjustment: Class ??? | |
