7.8.11.6. Application of Logical channel in the Hardware input for TC8 modules
See also:
Appendices 8.6. TC4, TC8, TC12 – THERMOCOUPLE SENSOR
Chapter 7.8.6. Logical Channels - Math function mode
Task:
In this example we calculate the mean value from logic channels 1÷8. In these channels
there are values from thermocouple sensors that are located around the furnace.
Solution:
Before measuring the temperature, the user should configure the device as follows and
then connect the thermocouple sensors to the device. An example of the connection is shown
in
Fig. 7.76. Schematic diagram for the
TC8
module
To configure logical channels for reading temperatures from 1÷8 inputs (names
Temperature 1
,
Temperature 2
, etc.) we should follow the same way as in
Application of Logical channel in the Hardware input mode for TC4 modules
For Logical channel in the
Math function
mode to calculate an average value:
–
touch the 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
(except 1÷8)
such as
9
,
–
in the
Name
parameter write
Mean value
,
–
Mode parameter set as
Math function
,
–
enter the
Function
submenu to select the appropriate function that allows the
calculation of the mean value,
