MiCOM P632
Scaling of BCD Output
|
|
In order to define the resolution for measured data output the measurand range (Mx,min ... Mx,max) in scaled form (as Mx,scal,min ... Mx,scal,max) and the associated BCD display range (BCD,min ... BCD,max) have to be set.
| ▪ |
MEASO: Scaled min. val. BCD |
| ▪ |
MEASO: Scaled max. val. BCD |
| ▪ |
MEASO: BCD-Out min. value |
| ▪ |
MEASO: BCD-Out max. value |
The BCD display range should be set so that the value 399 is never exceeded. If this should occur or if the measurand is outside the acceptable measuring range, then the value for "Overflow" (all relays triggered) is transmitted.
|
Measurands |
Range |
|---|---|
|
Measurands of the variable Mx |
Mx,RL1 ... Mx,RL2 |
|
Associated scaled measurands |
0 ... 1 |
Scaling is made with reference to the complete range of values for the selected measurand (variable Mx). The complete range of values is defined by their end values Mx,RL1 and Mx,RL2. (Mx,RL1 and Mx,RL2 are listed in the operating program under “minimum” and “maximum”.)

Measurands to be output |
Range |
|---|---|
|
Measurands to be output |
Mx,min. ... Mx,max. |
|
Scaled measurands to be output |
Mx,scal,min ... Mx,scal,max with: Mx,scal,min = (Mx,min - Mx,RL1) / (Mx,RL2 - Mx,RL1 Mx,scal,max = (Mx,max - Mx,RL1) / (Mx,RL2 - Mx,RL1 |
|
Designation of the set values in the data model |
"Scaled min. val. BCD" ... "Scaled max. val. BCD" |
|
Measurands |
BCD display values |
|---|---|
|
Measurands in the range "Measurands to be output" |
BCD-Out min. value ... BCD-Out max. value (Valid BCD value) |
|
Measurands: Mx,RL1 = Mx = Mx,min |
BCD-Out min. value (BCD value not valid) |
|
Measurands Mx: Mx,max = Mx = Mx,RL2 |
BCD-Out max. value (BCD value not valid) |
|
Measurands Mx: Mx < Mx,RL1 or Mx > Mx,RL2 |
BCD-Out max. value (Overflow) |
