The returned responding data include following content: the terminal slave machine address (Address), the executed command)Function), the requested data resulting from command executing (Data)and one CRC check code ( Check). Any error never lead to successful responding, or return one error indicating frame.6.2.1 Data frame formatAddressFunctionDataCheck8-Bits8-BitsN x 8-Bits16-Bits6.2.2 Address domainThe address domain is at the front of the frame, composed of one byte (8-Bits, 8 bit binary code), decimal scale is 0 255, in our system, only 1 247 is used, other address is reserved .these bits indicate the terminal unit address specified by users, this unit will accept host computer data connected with it. Every terminal unit address in the same FieldBus must be one and only, only the addressed terminal can respond the query including this address. When the terminal is sending one responding , the slave machine address data in this responding can tell host computer which terminal unit is communicating with it.6.2.3 Function domainThe function domain code tells the addressed terminal which function shall be executed .The function code and its meaning and function in this Series meters are listed below.Code (hexadecimal system)Meaningconduct03HRead register keepingAcquire current binary value from one or multiple register keeping04HRead input registerAcquire current binary value from one or multiple input register10HSetting multiple registerLoad concrete binary value into string continuous register keepingData domainThe data domain includes: the needed data for terminal to execute specified function or the collected data when terminal respond the query. These data may be value, parameter address or setting. Example： function domain tell terminal unit to read one register, data domain must specify: The reading is starting from which register and how many data is needed . For the embedded address and data, the content depends on the different type and different slave machine。6.2.4 Error check domainThis domain adopts CRC16 cyclic redundancy check, the data transmission checking function error of host computer and terminal is allowable. Because of electrical noise and other interfere, sometimes, -12-when one group data is transmitting from one unit to another unit, in the data transmission process, there may be some changes, the error check can ensure master machine or slave machine not respond those changed data, so, the security, reliability and efficiency of system are upgraded6.3 Error check methodThe error check (CRC) domain occupy two bytes, including one 16 bit binary value. CRC value is calculated by the transmission unit, then adding to Data frame, during accepting data , the accept unit is recalculating the CRC value, then comparing with the accepted value in CRC domain, if these two values is l'1 ot equal, the error occurs.When calculating CRC, at first, setting one 16 bit register as whole-1 ,then continuously calculating the 8 bit of each byte in Data frame with current value of this register, only 8 data bit of each byte is taking part in producing CRC, the starting bit and the stop bit and the possible parity bit have no influence to CRC. When producing CRC, 8 bit of each byte with content of register to do exclusive or, then shift the result to the low bit, the high bit is complementarity with 0", Least Significant Bit (LSB) is shifted and detected, if it is 1 ,this register carry out one exclusive or operation with one preset fixed value(0A001H)p if the Least Significant Bit is O, there is not any treatment.Flow of CRC forming：1 .Preset one 16 bit register as OFFFFH ( whole-1 ), called as CRC register 2 .Carrying out exclusive or operation between 8 bit of the first byte in the Data frame and the lower byte in the CRC register, to save the result back to CRC register.3 .Right shift CRC register for one bit, the highest bit filling O.the Least Significant Bit is shifted and detected.1 .lf the Least Significant Bit is shifted and as 0: repeat the third step(next shift); if the Least Significant Bit is shifted and as 1 iCarrying out exclusive or operation between CRC register with one preset fixed value (0A001H).5 .Repeat the third step and the fourth step, until 8 shift. So, one integrated 8 bit is treated.6 . Repeat the second step to the fifth step to treat next 8 bit, until all the byte treatment are completed.The final CRC register value is the CRC value.Another CRC calculation method is the look-up table technique with feature of fast calculating speed, but needlarger save space, please refer to related data.6.4Communication parameter address table (word ) for electric energy meterAddressParameterR/WValue rangeData type0000HPassword savedR/W0001-9999word0001HHigh byteCommunication addressR/W0001-0247word0001H Low byteCommunication baud rateR/W0-3：38400、 19200s、 9600、 4800bps0002HControl characterR/W8th bit-connection mode (0-3-phase-4-we, 1 -3-phase-3-wire) 7th bit-input voltage range (0-400V, 1-100V) second bit-input current range (0-5A, 0-1 A)word0003HPT transformationR/W1 -9999wordratio0004HCT transformation ratioR/W1 -9999word0005H - OOOAHtr.1-tr.4 4-channel transmitting parameterR/WEach channel occupy 3 bytewordOOOBH -0021HReserved0022HSwitching Input output stateR/WFor detail, see next page attached tableword0023H 0023H High byteDecimal point U(DPT)R3-7word0023H 0023H Lower byteDecimal point l(DCT)R1-50024H High byteDecimal point PQ(DPQ)R4-10word0024H Lower byteSymbol PQRHigh bit-low bit:Q, Qc, Qb, Qa, P, Pc, Pb, Pa;0= positive, 1= negative0025HPhase voltage UaR0-9999(Conversion formula based on 6.5.1)word0026HPhase voltage UbR0-9999(Same as above)word0027HPhase voltage UcR0-9999(Same as above)word0028HLine voltage UabR0-9999(Same as above)word0029HLine voltage UbeR0-9999(Same as above)word002AHLine voltage UcaR0-9999(Same as above)word002BHlaR0-9999(Same as above)word002CHlbR0-9999(Same as above)word002DHIcR0-9999(Same as above)word002EHPaR0-9999(Same as above)word002FHPbR0-9999(Same as above)word0030HPcR0-9999(Same as above)word0031HP totalR0-9999(Same as above)word0032HQaR0-9999(Same as above)word0033HQbR0-9999(Same as above)word0034HQcR0-9999(Same as above)word0035HQ总Q totalR0-9999(Same as above)word0036HPFaR0-1000(Same as above)word0037HPFbR0-1000(Same as above)word0038HPFcR0-1000(Same as above)word0039HPF totalR0-1000(Same as above)word003AHSaR0-9999(Same as above)word003BHSbR0-9999(Same as above)word003CHScR0-9999(Same as above)word003DHS totalR0-9999(Same as above)word003EHFrequency FRR4500-6500(Same as above)word003FH - 0040Habsorptive active electric energy secondary sideR/W0-999999999(Same as above)Long0041H-0042HRelease active electric energy secondary sideR/W0-999999999(Same as above)Long0043H - 0044HInductive reactive electric energy secondary sideR/W0-999999999(Same as above)Long0045H - 0046HCapacitiveREACTIVE ELECTRICENERGYSECONDARY SIDER/W0-999999999(Same as above)Long0047H - 0048Habsorptive active electric energy primary sideR(Same as above)Float0049H - 004AHRelease active electric energy primary sideR(Same as above)Float004BH - 004CHInductive reactive electric energy primary sideR(Same as above)Float004DH - 004EHCapacitive reactive electric energy primary sideR(Same as above)Float004FHMaximum demandR0-9999word0050H-0051HMaximum demand timeRMonth,dahounminuteLongSwitching input/output state ( 0022H )1.PZ72(L)、PZ80(L)、PZ96(L)2、PZ42(L)：0022H1615141312111098slD02D01DI4DI3DI2DMReserved0022H1615141312111098 1DMDI2DI3DI4D01D02D03D04Reserved6.5 Communication application6.5.1 Reading dataThe measuring value of this series is read out by 03H Command of Modbus-RTU communication protocol,the relation between the communication value and the actual value is shown as following： ( Default Val_t= communication reading, Val_s= actual value)Applied parameterRelationUnitVoltage value UA> UB、UCVal_s = (Val_t /10000 ) * (10ADPT)VCurrent value IA> IB> ICVal_s = ( Val_t/10000 ) * ( 10ADCT)Avalue PA> PB、PC、P 总、QA、QB、QC、Q总Val_s = (Val_t /10000 )*(10ADPQ )W、varPower factor valuePFA、PFB、PFC、PFSVaLs = VaLt/1 000NONDIMENSIONALFrequency FRVal_s = Val_t /100HzSecondary side valueVal_s = Val_tWh> varhElectric energy primary side measuring value adopts the floating point variable data mode.
