! All the settings of the individual channels may be copied and pasted to
another measurement channel. Detailed information is given in section
Copying channel settings .
Fig. 12.4 An example view
of the ‘Channel’ settings window (math channel).
12.4.1 Inputs
Depending on the channel selection, suitable settings are available:
Channel Type: Disabled (Disabled, Measurement, Computed, Modbus TCP,
Demo(TEST))
[1]
Input
[2]
: A (A, B, C, D, E, F, G)
[2]
Input number: 1 (1, 2, 3, 4, 5, 6, CJC
⁰C, CJC ⁰F)
[3]
Characteristic: Linear (Linear, depending on the module type)
[4]
[1]: The
“Channel Type” possible configuration:
Disabled
– the channel is off and not
displayed, Measurement
– measured process value from input module should be
assigned to the channel, Computed
– the mathematical formula used for calculations
must be entered
– more details in section
math channels , Modbus TCP
– select from
the drop down list the input configured in the Communication settings window,
Modbus TCP tab; Demo(TEST)
– a sin (t) function value is virtually generated, enabling
e.g. the communication test without the input signals applied.

For ‘Channel Type’
Measurement : a drop down list allows to select a suitable
measurement module slot. After the selection, on the right side of the list, the module
tag is displayed enabling its identification.
For ‘Channel Type’
Modbus TCP : the drop-
down list allows selection the appropriate sensor/device (Ethernet connection); in order
to facilitate identification, the description includes: the ordinal number of the register,
the device address and information about the server: IP address:Port.
[3]:
For ‘Channel Type’
Measurement : the drop down list allows to select an input number
of the measurement card to which a selected channel is to be assigned. For the IN6TC
and IN3 module, it is possible to select the CJC ⁰C or CJC ⁰F virtual measuring input.
Temperature measurement made with using an internal sensor is assigned to the CJC
inputs. The measurement can be used to compensate the cold junction temperature if
the thermocouples are connected directly to the module's terminal block.
