    Hi Mikhail,

    Thanks for the quick reply.

    I know there is the averaging check box, but can you please tell me exactly how it works. Any averaging is performed over a certain number of samples, so my question is how many samples does the built-in averaging takes and over what time period. I would like to have the new average on every minute based on the samples from the previous minute.

    You mentioned comparing my own calculated average with the built-in average. Could you please give me a hint on how to calculate my own average.

    Hi Mikhail,

    Trying to solve that command formula problem I have, I reverted Scada Server back to version 4.4 and now command formulas work.

    To be 100% sure, I have uninstalled 4.4 and installed 4.5 Server again. Command formulas don’t work. Then installed 4.4, formulas work.

    So definitely there is a bug in the new 4.5 Server.

    Hi Mikhail,

    Thanks for the tip.

    But before I managed to try it, I bumped into a trivial problem – can’t make the output channel formula to work. I wrote a simple formula – Cmd*10, but when I check “Communicator” “Device data” for the command value, I always get the original command value, not the one calculated by the formula. For example, command value =10, value from the Communicator is also 10, but it should be 100 because of the formula.

    I defined the formula by checking the “Formula used” check box, and writing “Cmd*10” into “Formula” text box. Then clicked the “Pass to Scada server” and then clicked the “Restart Scada server service”.

    Any idea of what am I missing here?

    In my machine I’m using Modbus function 16 for writing to holding registers. That’s why “Multiple is checked” to tell communicator to use function 16 instead of function 06.

    For example, if I send a simple number like 100 or 200, my modbus device receives 0. If I send binary hex data 00 64 (=100 decimal) my device receives 100.
    All that done directly from communicator.

    No, it doesn’t. I can only correctly send binary data from communicator.

    Hi Mikhail,

    Thanks for your replies, but I still don’t have the answer to my original question – what to configure and how in order to send a value as 2-byte integer to a Modbus device.

    Hi,

    I’ve installed the new Communicator. Now, when I send any value I get this log in Device Data / Commands:

    | 2 | 18/09/2015 10:14:55 | Command: type = Standard, device num. = 1, value = N3 |

    What does N3 mean?

    I’m still using the previous version 4.4 of Communicator and I can’t see command values there. Regardless of that, in “Standard” command type description provided in Administrator app, it says that for “Standard” type, command parameter is floating point number. And it seems that value entered is treated as such. So, I have no idea how to send an integer as command value.

    If it is necessary, I will install the latest version of Rapid Scada.

    Hi Mikhail,

    Is it possible to use Rapid Scada with Windows 10 IoT on Raspi? I guess running Scada Web could be a problem (not sure whether there is IIS for Windows 10 IoT), but having just Communicator and Server working would also be quite nice.

    Hello Mikhail,

    I’ve repeated the installation and configuration process on another windows 10 machine and everything is working now – I can access scada web page. Tomorrow I will try to find out what is wrong with my first installation. Definitely it has something to do with IIS serving .aspx files. I’ve tested my IIS installation with plain HTML and then the same HTML code wrapped as an .asp file. Both worked. Then I’ve used the same HTML code but this time as an .aspx. This time I got 404 error. So it means IIS server doesn’t know what to do with the .aspx and that is the reason why Login.aspx is not showing.

    By the way I’ve also installed Rapid Scada on my Windows 7 machine at home, just to check the installation and configuration steps again. At first I’ve got an error trying to open Login page. The reason was DefaultAppPool which was configured to use .NET 2.0 instead of 4.0. After I’ve changed it from 2.0 to 4.0 everything worked as it should. So this could be one of the reasons why other people have the same problem as I had.
