Hello,
1) Why kindly how do I enter numeric data or text type in the rapid scada example textbox in other platforms? Read bar code too?
If you need to send command to a device, you should create an output channel. See the default configuration, for example.
2) Is there any script language to programming events or routines or other logic associated with the tags?
1. You can use C# for writing formulas.
2. Automatic Control Module allows to send commands on different conditions.
