Degree Of Protection; Gain And Offset Calculation For Analog Values - Siemens LOGO! 24RC Manual

LOGO! Functions

4.3.5 Degree of Protection

The parameter protection setting allows you to specify
whether the parameters can be displayed and altered in
parameter assignment mode on the LOGO! module. There
are two possible settings:
+: The parameter settings are also displayed in parameter
assignment mode and can be changed.–: The parameter
settings are not displayed in parameter assignment mode
and can only be changed in programming mode.

4.3.6 Gain and Offset Calculation for Analog Values

The Gain and Offset parameters allow the internal repre-
sentation of an analog value to be aligned with the actual
measured value.
Connector voltage (in V)
Internal process image
Gain (in %)
Offset
A connector voltage of 0 to 10 V is mapped internally to
values of 0 to 1000. A connector voltage greater than 10 V
is also represented as 1000 in the internal process image.
You can use the Gain parameter to set a gain of 1000 % (a
factor of 10), for example.
You can use the Offset parameter to move the zero point of
the measured values.
You will find a sample application in the description of the
"analog comparator" special function on page 118.
For information on the analog inputs, see also Section 4.1.
