Hello.
I am using the free version of Rapid Scada. My objective is to establish a Webstation that can connect to multiple PLCs. Each PLC is connected to several devices and obtains information from them.
Here comes the problem: The PLCs are programmed so that they can only receive data from one device at a time. The device is selected by changing some outputs. The idea is to poll every device cyclically and store their data.
As far as I know, in order to send commands automatically, the Automatic Control module is needed. Is there a way to get around this without purchasing this module?
Thank you for the help.
