Thank you that worked perfectly.

Rapid SCADA is working really well.

Hi Mikhail,

I downloaded the update and copied the files into my “program files/SCADA” directory. I checked that the files had been replaced. I then uploaded the project and changed the publishing times. At 1 minute, it worked well. At 2 minutes, every second one failed.

Hello Mikhail.

Screenshoots:

https://ibb.co/qMbS10D1

https://ibb.co/M5KKjwwv

One shows the driver settings, one is the log just after restarting while the last is the log sometime after starting showing errors.

Thanks Mikhail,

The Archive table in the configuration database was exactly what I was missing – have corrected this and away it went. Great product.

Hi,

The standard archives are working well and saving data to postgresql, however I can’t make the custom archive work and indeed if I change the name of the standard archives (e.g. hour/hourcopy to 30min/30mincopy) they stop working.

I’m using the hour archive on a 30 minute period and it would be nice to make the name more accurate.

Is it possible to make the custom archive work or to change the name of the standard archives?

Hi

And if you want to change the password in ScadaInstanceConfig.xml, how do you encode it? e.g. to user koolbeer123 as a password what do you put in the ScadaInstanceConfig.xml?

Hi Mikhail

I found the issue. Regardless of what user/password you setup in the Server/module ModArcPostgreSQL Connection settings, rapid_scada uses postgres/postgres. If you change the database password to postgres it works.

Thanks Mikhail,

The settings were all OK for password auth. I tried changing to MD5 and trust, but made no difference. I also made a new user/password. I can connect to the database OK with either the postgres user or my new user using both pgadmin4 and dbvisualiser.

Not sure where to go next?

Hi,

OK tried that and discovered that autheication isn’t working. 100% certain login name (postgres) and password are correct. Any suggestions

Hi Mikhail,

I’m halfway through comissioning a solar farm, which is using rapid_scada.

Screenshots are here:postgre screenshots

Queries use Query Text

Hello,

I found the initial issue – I had the user name wrong ‘postgres’ not ‘postgre’. So now I have a connection but still don’t have any data being saved in the database. I also don’t have log files associated with the modules i.e. ModDbExport.log etc. Perhaps something is wrong with my installation?

I have followed the instructions in the documentation and created the query as per the link.

The more I use Rapid SCADA the more I think this is a really great product 🙂

Hi there

I use onedrive, with the ScadaProjects directory in the documents folder, i.e. the same place on any PC that I’m logged into onedrive on. That way I don’t copy it, just open it on the other PC.

Hi Mikhail,

For unknown reasons some channels seem not to generate events. The only way I found to fix this was to delete the channel, then recreate it with exactly the same definition and this allowed the limits to generate events. Note varying channel past the limit changed its colour, but didn’t generate and event.

Thanks all, Editing the format.xml in notepad++ worked 100%. I have now have some formats of 5000 characters long. I used excel and notepad to create the format and place in format.xml, then reloaded the application and downloaded it to test.
