Good. Dividing a double number by zero returns infinity instead of raising an exception.

But response is long and difficult to read. May be you should make a copy of the scheme, and delete components until error is occurred. Also you can try to find the problem looking in values in Communicator.

Thank you for the detailed error description. The cause of this error is different that the error in the beginning of the topic. Likely the problem is some unacceptable character that is contained in channel values. Just for example, infinite symbol.

You should open a Network tab in browser tools, find a request and copy a server response. In the response, there is a problem character.

Hi Rich,

The easiest way to calculate power consumption is using Elastic Report Plugin. The example is here.

The report can also be generated in HTML format and inserted into a web page view.

If you want to get a difference using formulas, you should create an input channel that stores a value hour ago. It’s tricky.

We are thinking about development of a module that can calculate differences between the current and archived values of the specified channels. If we found a sponsor, we could do it fast.

Hi Rich,

Could you provide links to screenshots of the settings and error?

[Mikhail]

Hi,
Please provide screenshots of your settings.

Hi,

It will be fixed in the next release. Version history is here. Look for “Schemes”

[Mikhail]

Hello,

Could you explain how does your plugin work?
It may help to find out why it affects interaction between Server and Communicator.

[Mikhail]

Hi,

You should use DB Import Driver.
If you face connection issues, read this.

Why do you need 2 copies of Rapid SCADA on the same machine?

[Mikhail]

May be it’s easier to use virtual machines. For example, you don’t install several PostgreSQL servers on a one machine even if it’s technically possible.

Hi,

If you want to create 2 different systems, you should create 2 projects in Administrator.
If you want to create a 1 distributed system, you should create several profiles within a 1 project.

All profiles use the same configuration database that is included in the project.

Could I install and setup multiple ScadaServer seperate by port on same machine ?

On Linux:
You can copy Rapid SCADA to different folders like
/opt/scada1/
/opt/scada2/
But during installation you need to change installation script to create daemons having different names.
Files to update:
apache/scada.conf
daemons/scadaagent
daemons/scadacomm
daemons/scadaserver
scadarestart.sh
scadastart.sh
scadastop.sh
svc_install.sh
svc_uninstall.sh
ScadaAgent/*.sh
ScadaComm/*.sh
ScadaServer/*.sh

Honestly, I don’t think it’s a good idea for beginning.

Please press F12 in browser, open the Console tab and make a screenshot of the error details.

What Windows version do you use?

[Mikhail]

Hi,

Now you should open the Output channel table in Administrator and create a new output channel. Specify a command number the same as you use for sending commands.

In Scheme Editor, add a button for example, and set its output channel to the output channel number that you have created.

[Mikhail]

SCADA-Server uses TCP port 10000 for incoming connections. You should check that other software does not occupy it.
