I use the Modbus TCP Client to poll a Modbus server and transfer the data to an MQTT-broker using the Data to Server Service. In both the Modbus TCP client and the Data-to-Server service the minimum poll period seems to be 1 second.
Would it be possible to allow for shorter poll periods? Modbus TCP can normally handle poll periods < 100ms.
I use the Teltonika RUT30X with firmware 07.05.4.
