Can a Sentera device with Modbus RTU communication work stand alone?
Yes.
All Sentera devices with Modbus RTU communication can be used standalone or they can be integrated in a Modbus RTU network. In many situations, the default parameter settings will be enough to start using the product. For the applications where some parameters need to be adjusted or optimised, we advise you to use Sentera’s free 3S Modbus software. Connect the Sentera device to your computer and the 3S Modbus software will automatically recognise the connected device. The Modbus input registers are read-only, the holding registers can be modified.
