) Note!
l Short−circuit unused inputs (connect positive and negative
terminals) or deactivate them by assigning the function number
FF
h
.
l In the event of an overflow or underflow, wrong values are
output. Strong signal jumps with sign reversal may occur.
I/O system IP20 multiplies measured values with decimal positions and without
normalisation by a factor and transfers them as integers to the bus. To output the
decimal positions, divide the measured values by the same factor.
Example:
Measuring task: Temperature measurement with signal function 01
h
. Measured value = 80.5 °C.
1. I/O system IP20 converts the measured value into an integer:
80.5 [°C] × 10 = 805
2. Reconvert the measured value to output it with decimal positions:
805[°C]
10
 + 80.5°C
