32-Bit values in two registers Values that exceed 65,535 are stored in two consecutive Registers and have to beinterpreted as "little endian" / LSW (Least Significant Word) firstExample Register No. 10 (AbsFlow LowWord) = 14,55110 = 0011'1000'1101'01112Register No. 11 (AbsFlow HighWord) = 1910 = 0000'0000'0001'00112AbsFlow HighWord 19 0000'0000'0001'0011AbsFlow LowWord 14,551 0011'1000'1101'0111AbsFlow = 0000'0000'0001'0011'0011'1000'1101'01112 = 1,259,73510 = 1259.735 l/hMath formula: AbsFlow = ( AbsFlow HighWord * 65,536 ) + AbsFlow LowWord AbsFlow = ( 19 * 65,536 ) + 14,551 = 1,259,735 = 1259.735 l/hDeactivated registersIf a register is not supported by a device or by a device setting it is indicatedwith 65'535 (1111'1111'1111'11112).2 / 6Modbus-Register 2-way EPIV • en • v1.0 • 05.2018 • Subject to changeswww.belimo.com2-way EPIVCommunicative characterised control valve with sensor- operated flow control, 2-way (EPIV)Modbus Register OverviewOperationNo. Adr.
