I have been working with Proview for several weeks now so I'm still a noob. Here are a few comments on first impressions.

What I like about Proview
1. Open source so I can learn from the code and add/subtract features as needed.
2. Enabling and disabling device polling via the Continuous attribute
3. Communication drivers built in.
4. Simple eternal C library code interface and the CArit objects are very nice
5. The exponential smoothing filter is pretty cool
6. The documentation and help class is very good so far.
7. This WEB site is helpfull
8. The Proview Development Console is very nice for simple debugging printf statements
9. No crashes on Debian 8!

What I dislike about Proview
It hard to complain about something you get for free, so I will just add a few constructive comments.

1. The learning curve is very steep for those of us new to OOP. Not really a Proview issue.
2. The graphical programming gets a bit messy and hard to find things, string search finds one string then stops.
3. I wish there were more active users on this WEB site.


Overall, I really like Proview. I have downloaded and used several open source SCADA type programs and I feel Proview is the best.

Good job guys! This really is something to be proud of.

Some history and more comments

My goal with this Proview project is to prove to myself its a viable SCADA option. So far things are going well.

I originally installed Proview on Ubuntu and had problem with the sev historian, Installing on Debian 8 solved this problem. Although I did have a crash in the sev historian this weekend by opening up a data set. This was the first crash since installing Debian 8.

The crash happened when I opened up a Mysql data set for a time longer than the available data in the database. No big deal as it did not affect anything else. I just restarted the sev historian and tried it again. The crash was repeatable.

With some help from the Forum, I have been able to modify the source code to my liking, I added a few features like, encapsulated MODBUS serial RTU inside TCP, a more descriptive(date time value) alarming text in the operator window and the little endian byte swap code to the ChanAi and ChanAo objects.

So far I have approximately 150 io points, ~100 Modbus TCP, 20 Modbus encapsulated RTU, 30 CIP/EtherIP all being stored to the MySql database.

I have a few more Proview projects to complete before claiming victory.
1. Getting the WEB interface up and running
2. Adding a new class for an io device
3. Cleaning up of the above mentioned hacks

I recognize the sev problem. This is probably fixed in V5.6.1.

/Claes

Is Debian 8 still the development and testing OS for V5.6.1?

Yes.

I've been trying to decide if the WEB interface is the way to proceed for remote access. I am thinking that a VPN connection with Proview installed on the remote laptop might be a better option.

What are the advantages of the WEB interface?
