Micom P634 - BCD Measured Data Output

3.10.2 BCD Measured Data Output
The user can select a measurand for output in BCD form by assigning output
relays.
The selected measurand is available in BCD-coded form for the duration of the
set hold time MEASO: Hold time output BCD. If the selected variable was
not measured, then there is no output of a measurand value.
3.10.2.1 Output of Measured Event Values
If the measured event value is updated during the hold time, the measurand
output memory is cleared and the hold time is re-started. This leads to an
immediate availability at the output of the updated value.
3.10.2.2 Output of Measured Operating Values
The selected measured operating value is available for the duration of the set
hold time. After the hold time has elapsed, the current value is saved and the
hold time is re-started. If the hold time has been set to blocked, the measured
operating value that has been output will be stored until the measured data
output function is reset.
3.10.2.3 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”.)
