Instruction Manual

Converting a BCD number into an analog value
BCD input values at inputs d1...d4 and d5...d8 are converted into a floating point number and available at output y1.
With a BCD number>9atinputs d1...d4 or d5...d8, output variable y1 is limited to 9. Out of the range, the out
-
put allocation is:
Output
d1 d2 d3 d4 d5 d6 d7 d8
00000000
y1 =0 0
11111111
y1 =9 9
Converting a value into selection “1 out of 8" (Select = ana<->1/8)
An analog input value at x1 (range 0...8) selects none or one of the 8 outputs z1...z8.
Example for conversion value (x1 = 5) into selection:
Input
z1 z2 z3 z4 z5 z6 z7 z8
x1 =5
00001000
Out of the range, the output allocation is:
Input
z1 z2 z3 z4 z5 z6 z7 z8
x1 ß 0
00000000
x1 ? 8
00000000
Conversion Selection “1 out of 8" into analog value (Select = ana<->1/8)
Individual digital input allocation d1...d8 result in an analog output variable at y1 according to the allocated input
value.
Example for conversion value (x1 = 5) into selection:
Output
z1 z2 z3 z4 z5 z6 z7 z8
y1 =5
00001000
If more than one of inputs d1...d8 is active, output variable y1 is set to 0.
