The Industrial Raspberry Pi Forum

Hi, I am trying to locate an example of use of revpimodio2 to write values to an AIO Modules and a MODBUS RTU device, What I mean by this is:
I am able to write values in my process image like:
rpi.io.OutputValue_1 = My_Value
And my Process Image takes such values. But when I want to verify they took effect by using Pictory command: "Load Start Config", I notice the changes did not take effect.
Why is that? Is it possible to use Pictory to verify that next time the config file is loaded, those changes are there?


Same thing happens with my Modbus RTU Master Virtual Device:

rpi.io.Output_Word_1 = My_Value
It does not show in Pictory when I reload the config file.

Thanks in advance...

PS. I want to clarify that at the current stage I am in, I am only configuring the modules and the physical units are not present. However, I assumed that for the sake of testing and simulations, this is possible to be done with Pictory.
Here's my piTest -d:

Hi Leo,

you can do this either cyclic or event-based.
