Figure 3-2 Default corresponding channel characteristics for each mode without changing the D0 and D1 values of each channel
The channel characteristics can be changed if the D0 and D1 values of the channel are changed. D0 and D1 can be set anywhere
between -10000 and 10000, if the setting value is outside this range, the VC-4DA will not receive it and will keep the original valid setting.
4. Programming example
4.1 Programming example for VC series + VC-4DA module
Example: VC-4DA module address is 1, so that it turns off the 1st channel, the 2nd channel outputs voltage signal (-
10V to 10V), channel 3 output current signal (0 to 20mA), channel 4 output current signal (4 to 20mA), and set the output voltage or current
value with data registers D1, D2 and D3.
1) Create a new project and configure the hardware for the project, as shown below
Figure 4-1 Hardware configuration
2）Double click on the "VC-4DA" module on the rail to enter the 4DA configuration parameters.
