    Datalogger setup in VCOM

    • Create a new datasource in VCOM and select device type Webdyn
    • Insert correct datalogger serial number and choose local recording interval settings


    Setup datalogger

    Communication

    • Please make sure that all datalogger assigned to one system in VCOM use the same recording interval to ensure that charts work properly
    • Copy given FTP access data in VCOM setup and insert it into datalogger setup
    • Perform communication test

    How to adapt meter scale factor

    If necessary the scale factor can be adapted in the meter config file, in our example the file is called "Secure_Elite_440_446.ini":

    20;20;R phase reactive power;8;2;1;;;1;0;kVAR;4
    21;21;Y phase reactive power;8;2;1;;;1;0;kVAR;4
    22;22;B phase reactive power;8;2;1;;;1;0;kVAR;4
    23;23;3 phase reactive power;8;2;1;;;1;0;kVAR;4
    24;24;R phase apparent power;8;2;1;;;1;0;kVA;4
    25;25;Y phase apparent power;8;2;1;;;1;0;kVA;4
    26;26;B phase apparent power;8;2;1;;;1;0;kVA;4

    29;29;Active Total import;8;2;1;;;1;0;kWh;4

    30;30;Active Total Export;8;2;1;;;1;0;kWh;4
    .....

    The factor can be changed in the 9. column "varCoeffA":

    Example active power
    19;19;3 phase active power;8;2;1;;;1;0;kW;4
    change factor from 1 to 0.001 (for conversion from W to kW)
    19;19;3 phase active power;8;2;1;;;0.001;0;kW;4

    Example active energy
    30;30;Active Total Export;8;2;1;;;1;0;kWh;4
    Change factor from 1 to 0.001 (for conversion from Wh to kWh)
    30;30;Active Total Export;8;2;1;;;0;0.001;kWh;4
