![]() ![]() This allows that in case of adding new features it is not necessary to remotely update the firmware of the entire modem pool, with the risk it involves, but only to update the software in one place, that of the MQTT platform the IEC protocol intelligence, DLMS/Cosem, modbus…) will be on the platform. The modems will act as “Transparent gateways Series – MQTT,” therefore the interpretation of the protocols (ie.The communication between platform and devices will be via MQTTS, which guarantees the connectivity required in the previous section and adds a layer of SSL security in the communications between platform and counter.Therefore, connectivity must always be established from the counter to the platform The SIM cards used may be from any operator, so it is not guaranteed that the IPs are public or fixed. In order to make the system cheaper, economic devices with 2G/3G/4G connectivity will be used, such as the MTX-4G-JAVA-T modem, whose model has an RS232 and RS485 bus, making it suitable for all cases.We want to read a large number of different meter boxes (IEC counters, counters with DLMS/Cosem protocol, modbus protocol network analyzers, etc.) All devices have an RS232 or RS485 serial port.
