Programming Examples - Veichi Electric VC-4AD User Manual

If you change the value of D0 and D1 of the channel, you can change the channel characteristics, D0 and D1 can be set
anywhere between -10000 and +10000, if the set value is out of this range, VC-4AD will not receive and keep the original valid
setting, Figure 3-3 shows the example of characteristics change, please refer to it.

4 Programming examples

4.1 Programming example for VC series + VC-4AD module
Example: VC-4AD module address is 1, use its 1st channel input voltage signal (-10V to +10V), 2nd channel input current signal
(-20mA to +20mA), close the 3rd channel, set the average number of points to 8, and use data registers D0 and D2 to receive the
average conversion result.
1）Create a new project and configure the hardware for the project, as shown below
2）Double click on the "VC-4AD" module on the rail to enter the 4AD configuration parameters.
