12 Modbus Protocol Protocol s FDC-/ Process / Temperature Controller *C: The parameters are preset with the default values specified in the table during production. *D: The scale values specifiy the transformation relation between the value of parameter and the value of register. The parameter with a scale low value is stored in the register with a number zero. The parameter with a scale high value is stored in the register with a number. For example, if a value is read from the addressed register, and LS = scale low value, HS = scale high value,then (HS LS) the value of the parameter = LS +x Similarly, before writing the value of parameter to the addressed register, the value W of the parameter must be transformed according to the following formula : (W LS)x (HS LS) Note that the value stored in the register is always positive value. PC Software/Discrete display devices allow for linear scaling of register values. The following examples will cover all registers in the / controller. For registers with Scale anges of - (low) to (high): Min aw = Max aw = Min EU = - Max EU = For registers with Scale anges of (low) to (high): Min aw = Max aw = Min EU = Max EU = Hi/Low adjustable range for each register is found in the parameter tables starting on page. Limits for each register should be set in the HMI/ device (from this table) to reduce the possibility of writing an out of range value to the controller. Writing an out of range value to the controller will result in the indication of an error on the front panel of the controller. *E: The unit means that the unit of parameter is the same as the unit of (process value ).The unit of is determined by MD, IN, IN, INU, and INU. *E: Unit determination for ASP, ADV and AHY If AFN = Unit same as unit of DE.HI, DE.LO DB.HI, DB.LO.H.L.H.L P..H, P..L D..H, D..L, *E: Unit determination for ASP, ADV and AHY If AFN = Unit same as unit of DE.HI, DE.LO DB.HI, DB.LO.H.L.H.L P..H, P..L D..H, D..L, *E: Unit determination for AMP Unit = SPMD = MIN. / Minute SPMD = H. / Hour *E: Unit determination for AOLO and AOHI If AOFN = Same unit as unit of P P SV MV MV, *E: Unit is the same as unit of ( IN ) *E: Unit is the same as unit of ( IN ) West th Place Bridgeview, IL Phone - -- Fax -- UMAA-Page
