Hello,
is there a library to manage the Modbus RTU with Processing?.
I found this link but the download is no longer possible.

> Hi All, Is there a library out there that can be used for sending serial modbus communications that hooks to processing? I have a pump which uses Modbus RTU in order to control the pump, as well as receive information as to the status of the pump (pressure, flow rate, remaining volume, ect.). I haven’t been able to find any sort of library for this, and am starting to think I may need to swap to another language that contains a library (they make a bunch for C and python from what I’ve seen). …
Do you have another solution?
Thanks in advance
Sylvain
