• Grid THDi L1, L2 and L3
• Compensation Ratio
• THDi setpoint (I set as 10)

I want to make a Meta Data Point with following code:

maxTHDI = Math.max(thdi_l1.value, thdi_l2.value, thdi_l3.value);

if (maxTHDI < (setpoint.value - 1)) {
    comp_ratio.set(comp_ratio.value - 0.01);
} else if (maxTHDI > setpoint.value) {
    if (comp_ratio >0.95) {
        comp_ratio.set(1)}
    else {
        comp_ratio.set (comp_ratio.value + 0.05);
}
}

RuntimeManager.sleep(15000);

My intention is:

• If the value of maxTHDi is lower than 9, then i lower the value of comp_ratio by 0.01.
• if the value of maxTHDi is above 10 then if comp_ratio > 0.95 then comp_ratio = 1 and if comp_ratio is lower 0.95, i will increase comp_ratio by 0.05.

I want to make this meta point run every 15 second, together with the polling of Modbus data point. However, every time I enable this meta point this kind of error appear in the logs and repeat lots of times:

Please suggest me some workaround.
