That helps me a lot, thank you.
Further clarification: What kind of command value are you using there? Is that a 1 for on and 0 for off?
Do you happen to have an example of what the output channels look like for you? I have created one for “Start” that ideally would be used to toggle one of the GPIO outputs.
Are these tied to the “requests” defined in the communicator application?
Thank you. From that point do you just use Create Channels under the services tab? It says the channels are missing, however it has the right DLL for my device (kprpi3).
At this point I am trying to understand how the output channels can send meaningful commands that operate the GPIO.
Gotcha, I understand that on the communicator. Now when it comes to configuring the output lines in the administrator? I would like to tie a command to a button that sends a value of 1 to a certain GPIO pin. Do I need to set up a device type that has the kprpi3.dll or can I use the modbus device type instead?
Ok, so I am creating a Raspberry Pi device in the administrator program. How do I create a device type that uses the kprpi3.dll? I am trying to configure the output channels so I can have a button toggle the outputs on a couple pins. In the communicator, I have a communication line set up with kprpi3.dll so I can configure request sequences with it, but now I need to figure out the outputs.
I have put the KpRpi3.dll in the ScadaComm/KP directory and restarted the service, but Rapid Scada is not recognizing that I have installed the plug in. Is there something I am missing? The Readme for the Raspberry Pi GPIO controller does not explain the installation as far as I can read.
Hi, currently working on implementing Rapid Scada for a University Engineering project. I am still fairly new to the Raspberry Pi and Scada software. I have also noticed that Rapid Scada has a Raspberry Pi 3 GPIO controller. My question is, can I use this controller to read data from a sensor plugged into the GPIO pins, and then use Rapid Scada to control a few relays?
If this is not doable, are there any resources on getting Rapid Scada to work with OpenPLC? I know they communicate via Modbus/TCP but I am still new to the protocol and am not sure how to make them work together.
