Hi Mikhail,

I configured custom period to 00:30:00. Somehow after I saved and upload to server the custom period became 00:00:00. I tried many times the custom period looks like always reset to 00:00:00.

<?xml version=”1.0″ encoding=”utf-8″?>
<ModDiffCalculator>
<GeneralOptions>
<CmdCode />
</GeneralOptions>
<Groups>
<Group active=”true” name=”30 Minutes” periodType=”Minute” offset=”00:00:00″ delay=”10″ archiveBit=”1″>
<Item srcCnlNum=”101″ destCnlNum=”102″ />
</Group>
</Groups>
</ModDiffCalculator>

The module log:

I checked result from excel is the different calculation is based on 1 minute.

Hi Mikhail,

I have one question; example if there is no data/data lost (channel 101) before 9:00:00 PM but resume back before 9:30:00 PM, what happen to the ModDiffCalculator module to calculate (channel 102) at 9:30:00 PM?

Channel 102 (9:30:00 PM, data?) = Channel 101 (9:30:00 PM, got data) – Channel 101 (9:00:00 PM, no data)

Pls advice and thank you.

Hi Mikhail,

My mistake; I thought Rapid SCADA will automatically create the rapid_scada database in PostgreSQL.

I manually create the rapid_scada database and everything works as expected.

Hi Mikhail,

Noted. I try calculate power consumption by using current data at the moment.
Thank you.

Hi Mikhail,

I have Elastic Report but what I want to do is to use the result/value from the calculated channel (e.g., power consumption) to show in table and to plot on chart.

Hi Mikhail,

Let say I have a Real Channel (101) to read meter energy kWh data, I configure a Calculated Channel (102) to calculate how much energy used in 30 minutes. In my script when every 30 minutes interval time, I will take the Real Channel (101)’s Current reading and access PostgreSql Minute Archive database to search for the same Channel (101) but DateTime is past 30 minutes ago to get its value. Thus I can get their different to become the result.

Hi Mikhail,

Right now I have weeks of data in Postgresql database. I am thinking of write a script in Formula to pull past DateTime Cnl channel’s Val value from database for further processing in real-time.

Can I do that? Pls advice and thank you.

Hi Mikhail,

I configured PostgreSql as my main achieve now. This is great.
Thank you.

Hi Mikhail,

Noted. Looks like I shall get used to the method:

“click and hold a left mouse button, then move the mouse to select the required period of time”

Thank you.

Hi Mikhail,

I can see my data store in PostgreSql now.
Can I just use PostgreSql as my main and only achieves? Like below setting.

Hi Mikhail,

If this this the case, can I configure the ChartPro starting time always start from 7am and end 7am the next day?

Currently the default start time is always start from 0:00 and end 23:59.
Pls advice and thank you.
