Only Archive on “Status change”

[TroyV23]

Im attempting a different path, so I’ve created this feed using the API:

https://i.postimg.cc/sxZ2X3B3/tmp-1de38a8b-3926-45a1-9bc3-bfc23f60969d.png

I am not able to display the channel number it always displays as undefined.

mainApi.getHistData(ARCHIVE_BIT, timeRange, “55500-55508”, function (dto) {
let outElem = $(“#divData2”);

if (dto.ok) {
outElem.html(“”);
let timestamps = dto.data.timestamps;

if (timestamps.length > 0) {

let trend = dto.data.trends[0];

let table = $(“<table></table>”);
table.append(“<tr><th>Date</th><th>Time</th><th>Channel</th><th>State</th></tr>”);

for (let i = 0; i < timestamps.length; i++) {
let timestamp = timestamps[i];
let record = trend[i];
let state = record.df.dispVal;
let channel = record.cnlNum;

// Only show On/Off
if (state !== “On” && state !== “Off”) continue;

let dt = new Date(timestamp.lt);

let day = String(dt.getDate()).padStart(2, “0”);
let month = dt.toLocaleString(“en-US”, { month: “short” });
let year = dt.getFullYear();

let hours = String(dt.getHours()).padStart(2, “0”);
let minutes = String(dt.getMinutes()).padStart(2, “0”);

let dateStr = ${day}-${month}-${year};
let timeStr = ${hours}:${minutes};

// Pick CSS class
let stateClass = state === “On” ? “state-on” : “state-off”;

table.append(
`<tr>
<td>${dateStr}</td>
<td>${timeStr}</td>
<td>${channel}</td>
<td class=”${stateClass}”>${state}</td>
</tr>`
);

The existing API does not return a channel name. However, you could implement your own API to do that.

About the 2nd question:
Perform console.log(dto) to check the object contents.

I’ve made my own custom html using the API and a imported CSV to fill channel names which is working really well now.

The problem I’m still having is the polling timing, even though I have it configured to write on change, you said it should be checking status approx. 10 times a second.

My data shows it is only checking approx. every 102 to 105 seconds for changes, and then it posts a whole bunch of “changes” with identical time stamps, when in reality those events all took places many seconds apart.

Any idea what can cause this delay for checking on change status?

Hello,
What is the architecture of your solution?

[TroyV23]

This is how it is set up right now:

Running Windows Server 2019 (x64) on Web server, and 2022 (x64) on the Application Server.

[TroyV23]

Is this possibly an issue?

The architecture is OK.
The last image cannot be open.

Is this ok?

The highlighted value is too big. Use a value from 0 to 1000.

I have a custom Historical archive configured to write on change, and periodic is not checked. IT is working most of the time, but sometimes I see some glitches.

The communication line I’m polling has about 10 devices, each with about 100 digital inputs. I made a custom historical archive so that only status changes OFF-ON or ON-OFF will generate a database entry. For some reason I still get certain inputs with multiple ON status in a row. What can cause this?

Hello,
Please provide the corresponding screenshots.

Here is the current archive config:

Here is a sample output using the API:

output

There are repeated entries here all in OFF state which should not trigger more than once. I have another data logger running and confirmed the status has not changed in this time.

I am wondering if another channel changes value, are all others re-checked even if they did not change?
