7.8.6. Logical Channels - Math function mode
Task:
This example shows how to measure voltage and current and calculate a power
consumption of the heater. Voltage, current and power of the heater must be display in one
window in needle dials mode. Additional in this example user must use external converters to
measure voltage and current exceed the range of
UI4
input module.
Solution:
First configure the device as described below, then connect the heater to converters and
then to the device (in accordance with
Fig. 7.57. Schematic diagram for the
UI4
module
In the next step you need to define three logical channels: for current, voltage and power. To
do this:
a) For a current,
–
touch screen and press the
Menu
button,
–
press the
Device configuration
button,
–
enter the
Logical channels
menu,
–
using the arrows in the top navigation bar, select any
Logical channel
such as 20,
