FinalValueMeasuringChannel
M [Offset ] = [ phys. MeasuringV alue ]
Description:
[MW]: Current read value across the channel input [V].
[FinalValueMeasuringChannel]: Value at a voltage input
of 10 volts.
Example 1: A sensor having a sensor constant of
10V=1500W/m² ís to be connected to an analog
channel. The final value of the measuring range is 10V.
Accordingly, the gradient is calculated as follows:
Gradient =
Explanation:
[MW]: Current measuring value across the channel
input in [mV].
[Final value of measuring scale]: At a current input of
20mA.
8.2 Digital inputs
The conversion to a physical unit is based on the
following equation:
phys.MeasuredValue =
1500W / m ²
= 150
10
If the channel does not show any offset during the
calibration, then 0 can be entered for this channel.
Assuming that the channel has an offset of, e.g.
+15W/m² during calibration, the channel must be set as
follows:
Offset = −15W / m²
Example 2: A PT100 is to be connected to a channel
via a measuring transducer. At +100°C the measuring
transducer supplies an output voltage of 10V, and at
–50°C it supplies an output voltage of 0V.
This results in the physical final value of measuring
range vs. 150 °C. It follows that the gradient is:
150°C
Gradient =
= 15
10
As the temperature is to be measured up to –50°C,
it follows that the offset is:
∑ pulses
time.cons tan t
Example: A meter supplies 6000 Imp/kWh and is to
be connected to a digital input. This metering constant
is entered directly as a value under “pulse constant”
(Imp./kWh], so that the values already appear as
energy values [kWh] on the online display.
To display the current energy reading, a value must be
entered in the field [Interval for current output(s)] , e.g.
60. In this case, the pulses are summed up over a
period of 60 seconds and converted to a mean output
value over the entire interval period.
8.3 Alarm criterion
Another example is used to explain how convenient and
effective plant monitoring can be achieved:
Example: A photovoltaic installation is equipped with
a radiation sensor to measure the solar radiation
(insolation) at the module level, and with a power
generation meter with pulse output. Based on these
parameters thresholds are to be defined which trigger
an alarm message to report a defect or malfunction
within the plant.

The limiting lines are now defined by the following
formulas:
8.3.1 Basic principle of monitoring
This example is based on the physical ratio between
the solar radiation (insolation) and the generated power;
under ideal conditions, this ratio would be as follows:
Lower limit:
Y < mlower ⊗ X ⊕ tupper
Pac < mlower ⊗ (GModule⊗ AArry⊗etaPV ⊗etaWR ) ⊕ (tlower ⊗ Pnenn )
[generated power] = [Insolation * AreaModule * etaModule*
eta inverter ]
Upper limit:
Assuming a PV module having a degree of efficiency of
12%, an inverter efficiency of 91% and a module area
of 10 square meters, the ideal ratio is shown in the
graph below:
Y > mupper ⊗ X ⊕ tupper
Pac > mupper ⊗ (GModule⊗ AArry⊗etaPV ⊗etaWR ) ⊕ (tupper ⊗ Pnenn )

y Status: “active“
y Time: “Interval“
y Alarm target (contact) “Standard contact“
y Type of message: E-Mail
y Delay: “8“
(triggering an alarm delay of 2 hours
at a measuring interval of 2 hours).
As in reality this ratio is not exactly linear over the
entire range (smaller amount of solar radiation =>
lower degree of efficiency), a solution must be
found to obtain a functional error messaging
criterion.
We are therefore “opening up” a range in which two
read values can occur. This requires two formulas
for calculating straight curves, which form the upper
and lower limits of a “plausible” range.
To send an alarm message the
contact must be defined in the menu

To gain more freedom and flexibility when selecting a
range, two different gradients can be defined.
The shift of the straight line by tupper and tlower is to be
defined as an absolute value (e.g.: 0.2kW).

8.4 Programming criteria based on the example of
an inverter comparison
In this example the daily yield of INV4 is compared to
that of INV5 and in case of a power anomaly an alarm
will be activated. Varios kinds of inverters can be
compared. Please create relations in the settings and
activate the criteria. Then enter if you wish to calculate
the criterion at each logging interval or once per day.

In the field “formula settings”, enter the daily yield
abbreviation of the respective inverter under x,y.
(In our example this is EINV_3, E_INV4).
The shift of addresses results from the fact the proLOG
addresses start with “0” (daily energy of INV 5 Î
EINV_4). This value is subsequently divided by the
installed generator capacity, thus allowing a comparison
of the values of different inverters. The upper and lower
limits can be set under item c; the gradient is set under
item m. The gradient may remain unchanged in most
cases.
