[2]: Parity control of each bite.
[3]: In RS-485 standard, up to 32 transmitters / receivers can be connected to the data
transmission line. Each slave-type device must have a different address assigned.
For more information on Modbus registers addresses and data format refer to section
MODBUS RTU / MODBUS TCP TRANSMISSION PROTOCOL .
12.4 Channels settings
The channel number is selected using the drop-down list, located in the upper left
corner of the screen. The description of the channel can be edited by clicking on the text in
Tag field. Then, the screen keyboard will pop up.

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, Demo(TEST))
[1]
Input : A (A, B, M)
[2]
Input number: 1 (1, 2, 3, 4, 5, 6)
[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 are in section
math channels , Demo(TEST)
– a sin (t)
function value is virtually generated, enabling e.g. the communication test without the
input signals applied.
[2]: 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.
[3]: The drop down list allows to select an input / output number of the measurement card
