I am fairly new to RapidSCADA (it is my first project).
I have managed to configure an interface that communicates with an Arduino, via Modbus TCP and read all the sensors data from it (I primarily read floats from Arduino and managed to do that by byte swapping, when defining the input channels in the Device Template Editor).
Now, I want to send data to the Arduino (setpoints for each measurement) so that the Arduino knows what to do with each measurement. Problem is I can’t figure out where and what to write in order to write the holding registers to Arduino, via Modbus TCP.
Currently, you should use formulas of output channels to swap bytes.
But the new version of the driver, which supports swapping bytes for commands, is under construction now.
If you can wait for a week, we can send you a new version. In this case, please write an email to our info@…org
Otherwise, please translate this answer by Google Translate.
Thank you for the fast response.
I can wait a week. Will send you an email just shortly.
But, I still don’t know how to define an output channel, to write into the registers. Should I add commands in the Device Template Editor? Like so?[img]http://savepic.net/10148875.htm[/img]
And where can I find the formula table?
