Modbus newbie: Sending Data Over Modbus from Linux


Thread Starter


I'm newbie in Modbus. I need to send to a SCADA the values read from SMS and the phone number who sent it periodically. I receive the SMS on Linux. How can I send these informations over Modbus?

On the one hand, this task seems pretty simple. On the other hand, the devil is in the details. It would take quite a while to give a primer on Modbus, but the bottom line is that you can find a library for Modbus on Linux, and whoever is running your SCADA system should be able to give you information on where to send the data. Getting this setup to be reliable and secure is going to be the real challenge.

I suggest starting with the technical resources at,
