The company I am at recently bought a centrifuge that comes with VS1ST AC Drive imbedded with RS-485 communications that supports the Modbus RTU protocol. We are an herbal company using it to separate extract from the herbs and other solids that macerate. Currently we only use it when we are on premises. I would like to use the tech. that comes with it to run it 24/5. All I would need in the software is assurance on safety and be able to monitor it or be notified to my smart phone if there were abnormalities in its performance. Automatic shut down or anyone linked could shut it down off premises. I found one in a brief search OPTO 22. any suggestions on any software that can do something so simple would be a great help!
