  • Page 24: Tcp/Ip Connection Via Mobile Network

    11 TCP/IP CONNECTION VIA MOBILE NETWORK It is possible to interact with the data logger by establishing a direct TCP/IP connection via mobile network with a remote PC connected to the Internet. The connection can be of two types: 1) Data Logger = Client , PC = Server The data logger acts as TCP client and requests the connection to the PC, the PC acts as TCP server and waits for the connection request.

    12 MODBUS The complete list of MODBUS registers for “Slave” mode is shown below. Depending on the system configuration, some of the listed registers could not be present if not significant for that particular system (for ex., atmospheric pressure measurement will not be available if it is not measured by the data logger).

For the calculation of the average direction, also called “prevailing direction”, the velocity versor (unit vector having the same direction of the velocity vector) is considered for each measurement, and the versor coordinates along the measurement axes are calculated, then the average of the coordinates along each axis is calculated.
