hi, JoelHaggar and CraigWeb:
I'm in business trip and cant access mango system as it run internally.
I will provide more detial info after I come back. sorry.

Hi, JoeHaggar:
all kinds of events, I set all events warning to raise message, but I turn off all events raise except value limit, so it generate less messages than before, but still a lot for me, as i said human only have interesting to read one hundred messges, more than that, equal to nothing and waste time to click confirm button in crazy. For my proposal, if system can filter top 20 important messages for me or inactive automatically for some not important messages after a peroid may be much better.

Thanks, MattFox, that's a good idea to use meta point to solve this problem, But as you said for already in raising alarm, it won't drop until it's reset. I curiouse about how 1000 points or 3000 data points handle this issue? I only have 20 data source (200 data points) that bring alarms really huge. Human ony have interesting to read one or two hundreds events, but I have 100,000 events generated within one week.

I already forbid all events except datapoint value limit alarm, any method to reduce the bounce?

Is there a way to let system only send one alarm for one thing happen, there are too many repeated event alarms for the same event thing. Which file make event alarm keep repeating? can I modify it to let it only issue event alrarm once no more repeat, no more duplicate?

Thank you! I am working on it. By the way, are there any scripts to read the highlimit or lowlimit of a certain XID?

For example, there is a data source has 20 data points, I want to know how many data points' value are out of range, any scripts for that?

that's great!

For text renderer properties, if choose Type Range, how to show number instead of show Text, for example, I do not want to show Text "High Temperature" From 30 to 50,I want to show it's value "43" with red color

thank you!

@joelhaggar said in Hardware parameter to recommand?:

How many users will there be?*
less than ten online
How fast will you be updating and logging points?
5 minutes
What protocol will you be using?
modbus tcp
How long do you need to store data for?
3 years
What other features will you be using?
just features as system default, chart\report etc.
What operating system (Windows or Linux)?
now I wish to use Linux

For 2000 points, what kind of hardware at least needed?
For CPU: i3, i5 or i7? can Raspberry do this work?
Anything else bottleneck of hardware that we need concern?

understand now, thanks.

something may caused by Java are difficult to encode than C++, as i know so far ifix project etc. are not succeed to be decoded.
many companies, especially manufacture companies, they do not let there equipments link to outer internet for safety reason, so you can not build a server in your side that under your control. you have to provide the whole software run in customer's factory internally.

How about windows version? installed on a computer, eveybody can access to use this computer? Normally, you make a project for your customer, you should give the whole software to customer, so your customer can modify it or resell it or copy, distribute it as they want, and you are out of control it..
As for other kinds of SCADA system, normally it set password for a project, and not allowed reset or decode, customer have the right to run the project, only the project designer havs authority to modify the project, says, run version and development version, that's the way how to protect project designer's work, sometimes related to payment things.

I see, but now I worry about two things:

1. If everyone can reset password, then eveyone can be admin authority?
2. In this way, customer or somebody else can get full access to my project, for modify, copy, distribute etc.
   how to protect my work? Is that the old version are not allowed to reset admin password?

I forgot the password of admin, how to get it back? or how to reset the password for admin account?
