Analog Value Processing
S5-115U Manual
470 Analog Output Module:
Connect the indicating instrument directly via the module's front connector
(pins: QV0, S + 0, S - 0, M
ANA
).
The analog output modules outputs a voltage between 0 and 10 V to the indicating instru-
ment, thus making it possible to read the liquid level as an analog value (Figure 10-34).

Program Structure
Call and initialize "Read analog value" function block FB250 (for conversion to a range of from
0 to 1000 cm [XA parameter]).
Generate the limiting value (PB9).
A flag (F 12.6) is set when the liquid level exceeds 900 cm.
Call and initialize "Output analog value" function block FB251 (for conversion of a value in the
range from 0 to 1000 cm [XE parameter] into a value between 0 and 1024 units for the AO 470).
Integral function blocks FB250 and FB251 are discussed in detail in Section 10-9 under the heading
"Integral Function Blocks".
