Task:
l
C0472/1 = 1.05 %. Write this value to C0141.
Configuration:
l
Connect FEVAN1-IN (C1096) to FCODE-472/1 (19521).
l
Connect FEVAN1-LOAD (C1097/1) to FCODE-471.B0 (19521).
Parameterization:
l
Set C1091 = 141 ( C0141)
l
Set C1092=0 (no subcode)
l
C1093 = calculate numerator
l
Set C1094 = 0.01 (two decimal places)
l
Set C1095 = 0 (no offset)
