MikhailModerator1. Could you provide an example, please?
2. Probably you should implement or purchase development of the device driver if your device uses its own communication protocol.
MikhailModeratorHi,
What version of Rapid SCADA do you use?
MikhailModeratorNo, it’s free. There is an extended commercial version.
MikhailModeratorStrange. May be it is cached. I’ve sent by e-mail.
Or you can download the distributive from rapidscada.org
MikhailModeratorIt is too old.
Should be 17.09.15 and 27648 bytes. Please update.
MikhailModeratorCould you post here the size and modify date-time of C:\SCADA\ScadaWeb\bin\ScadaDiag.dll ?
MikhailModeratorShow chart issue:
Try pressing Ctrl+F5 to fully refresh the web page. The location of ScadaDiag.aspx was changed to diag/Diag.aspx
MikhailModeratorMy advice was inaccurate.
You should create an output channel with standard command type.
In the source of your formula create a byte array of 8 elements:byte[] arr = new byte[8];
Fill it by the required values. Then convert back to double using BitConverter class:
return BitConverter.ToDouble(arr)
MikhailModeratorThis is outdated link. I will check the errors you described.
MikhailModeratorWhen you updated SCADA-Web? The 2nd bug was fixed in this week.
Try downloading again and overwrite ScadaDiag.dll
MikhailModeratorYou need to create your own function in Formulas table which converts double input value to the array of bytes. Then use your formula in Output channels table.
Also you need to upgrade SCADA-Server to 4.5.
MikhailModeratorHow the command is configured in the device template? Send a screenshot, please.
MikhailModeratorFirst of all, you should find where the value got lost.
Please remind me, if you send command by SCADA-Communicator directly, it works OK?
MikhailModeratorIt is a displaying bug )
It was fixed yesterday, but not published. Sorry. I shall do it till the midnight.
MikhailModeratorHi,
Double value is trancated by Modbus driver. Value type is not a problem.
You could update SCADA-Communicator only. It’s easy. Make backup copy. After updating, copy the config folder and check the settings. -
