Chart Pro and Elastic Report 32 days Length Questions.

[SkyE]

Here are some questions about our tests to learn flexibility;

1- In Chart Pro, the maximum total period of data display shown as 32 days. Is it possible to extend it?
2- Is it possible to show last data value in Scada during any connection loss with any aquipment.
3- Is there any “avarage value” function in Scada? For ex: we have only P, active power, from device and we want to calculate energy value daily, monthly and yearly. What could be done for this purpose?
4- Elastic Report Plug-in also works 32 day peroid?

1. 32 is a constant in the source code. If we increase this value, the performance becomes slow.

2. Yes, you need a formula of in input channel like the following:
Stat > 0 ? Cnl : Val(); Stat > 0 ? Stat : Stat()
Be careful, because a connection issue would not be detected in time.

3. It’s possible to create formulas that performs the required calculations. It can be done as a part of our consulting service. This is out of free support.

4. 32 days limit applies only if you choose a daily period. In case of using monthly period, there is no such limit.

1. Is it a source code that we can modify and which source file? We want to test the optimum speed.

4. Is it from “ElasticRepExample.xml”? Is it possible to expand 32 days limit in daily period?

Thanks for replies.

Option 1. You can change this line and rebuild Report.dll

Option 2. You can purchase a modification of the plugin to allow editing this value in the plugin settings.

Hello Mikhail,

About formula,

Stat > 0 ? Cnl : Val(); Stat > 0 ? Stat : Stat()

I tried the formula type mentioned above but just first formula is working “Stat > 0 ? Cnl : Val()” . How these both formulas are working in same line?

[Mikhail]

Semicolon splits a formula into 2 parts. 1st for value, 2nd for status.

The details is here http://doc.rapidscada.net/content/en/software-configuration/using-formulas.html

I don’t check formulas posted on the forum. This is just an idea. Creating well tested formulas is a commercial service.
