Example of a circuit for FIX32 format with % scaling
Task:
l
C0472/1 = 1.05 %. Write this value to C0141.
Configuration:
l
Connect FEVAN1−IN (C1096) with FCODE−472/1 (19521).
l
Connect FEVAN1−LOAD (C1097/1) with FCODE−471.B0 (19521).
Parameter setting:
l
Set C1091 = 141 (
¢ C0141)
l
Set C1092 = 0 (no subcode available)
l
C1093 = calculate numerator
l
Set C1094 = 0.01 (two decimal positions)
l
Set C1095 = 0 (no offset).
