Modbus
You can see current analog input value in decimal and hexadecimal for all related
Modbus address.
On Output tab, you can write value to analog and digital output channel, as well as
configure all related setting. There are also two tabs on the Output tab: Channel set-
ting and Modbus. Refer to Figure 5.11 below.

Channel Setting
Similar to analog input configuration, you can set different range for each analog out-
put channel. Select the channel number in the Channel index combo box, and then
select the range in the Output range combo box. After selecting appropriate range,
click the Apply button.
At the bottom left-hand corner of the Output tab, you can define the analog output
value by using the horizontal pointer slide or the Value to Output text box. After you
have chosen the appropriate analog output value, click the Apply output button.
Besides, you can set the startup value of the specific analog output channel. (The
analog output channel will generate the startup value output when it is power-on. In
other words, start-up value can be considered as a power-on value.) Use the hori-
zontal slider or the Value to output text box to define the value and click Apply but-
ton. Then click the Set as startup button to save that value as startup value.
At the bottom right-hand corner of the Output tab, it is Calibration area. There are
two buttons used to calibrate the maximum and minimum value of full range. The
label on the buttons will change depending on the output range. Take figure 5.11 as
example, labels on the two buttons are Trim for 4 mA (calibrate for minimum value of
full range) and Trim for 20 mA (calibrate for maximum value of full range).
After you click one of the buttons, one dialog window will appear. Use another instru-
ment to measure the output value. Then use the four buttons (-10, -1, +1, +10) on the
dialog window to correct the analog output value. For example, if you click the Trim
for 4 mA button, the specific analog output channel should generate 4 mA. However,
the instrument reads 3.88 mA. So you need to use +1 and +10 button to adjust the
output value, until the output value is truly 4 mA.
In the top right-hand corner of the Output tab, you can control the digital output value
by the DO 0 and DO 1 button. Their value will be display by the LED near the button.
