11. SERIAL COMMUNICATION. AVAILABLE SOFTWARE AND USB DRIVERS
Communication with the controller is possible through each of the available serial interfaces (independently, i.e.
RS485, Ethernet and USB) and can be useful (or necessary) in the following situations:
- remote monitoring and recording of current measurements as well as control of the operating status and control
algorithms for outputs,
- quick configuration of parameters, including copying settings to other controllers of the same type
In order to establish long-distance communication, a connection should be made in the
RS485
standard
(MODBUS-RTU protocol,
chapters 11.3
and
11.4) or
Ethernet
using the MODBUS-TCP (
chapter 11.2
) and MQTT
protocols (
chapter 11.1
).
When the controller (or RS485 converter) is connected to the computer for the first time via the USB port, the
system will start the process of automatic installation of the COM serial port driver (from the
Windows Update
website). Alternatively, you can manually indicate the location of the driver on the computer's disk from the
Device Manager
, following the instructions of the installation wizard (for the regulator, select the"AR2xx
