Ratio Setting (Block Model 033)
Section 6-9
2: SP Numerical Value Display and Input
This field sets the Ratio Setting SP. Settings from 0 to 1 represent 0.00% to
100.00% and the value multiplied by the K1 ratio (
−
10.00 to 10.00) can be set
and displayed.
Touch this field to display a ten-key pad below it.
Writing is performed for tag ITEM SP_W (ITEM 023) using the Before Writing
Numeral/String macro condition. The calculation given above is reversed and
the result (percent data) is written.
• Unit scale setting: Multiplier fixed at 0.01 and offset fixed at 0
• Input upper/lower limits: Upper limit fixed at 1,000 and lower limit fixed at
−
1,000
• Macro: The Before Writing Numeral/String macro is set as follows:
$W2047=GETNUMVAL();
READCMEM($W32691, [K1(054)], 1);
$W32694 = ($W2000/($W32691/1000))*100;
WRITECMEM([SP_W(023)],$W32694,1);
RETURN(1);
When the ten-key pad is displayed, the tag ITEMs R/L_SW and CAS_SET are
referenced and if R/L_SW is 1 and CAS_SET is 1, a message is displayed
indicating that the SP cannot be set, and input is disabled. (The operation of
this error message is the same in the Basic PID Block (Block Model 011).)
3: SP Setting Scale
The upper limit of the scale displays the ITEM K1 value from the SP Numeri-
cal Value Display and Input Field.
• Unit scale setting: Multiplier fixed at 0.001 and offset fixed
• Display: The display is decimal, one-word signed INT, and displayed with
a precision of 1/100 (

) in the rough font. A Control Flag is set to
disable input without displaying a surrounding box.
• Communications address: Set K1 (054).
The lower limit of the scale fixes the label at 0.00 is displayed in the rough
font.
