Hi,
You can also use BitConverter.GetBytes as a formula of an output channel to convert a number into array of bytes:
BitConverter.GetBytes((float)Cmd)
In this case may be it’s faster to install Rapid SCADA manually as written at http://doc.rapidscada.net/content/en/installation-and-run/manual-installation.html
Please check the following:
1. Does the folder C:\SCADA\ exist?
2. Run services.msc
Do ScadaCommService and ScadaServerService exist?It means that Rapid SCADA already installed. If you need to reinstall it, uninstall the existing one.
To change the password you need to login. You can change the password in the configuration database to make them matched.
After password is changed in XML, you need to restart the web application. You can do it using IIS Administration console or by restarting the PC.Don’t need.Hi,
The easiest way is changing password by editing C:\SCADA\ScadaWeb\config\WebSettings.xml in your favorite text editor.The script to export data executes when the data are received by SCADA-Server. You can create a stored procedure (function in Pg) that filters data according to your needs and use this procedure in DB Export Module.
It is possible to upgrade KpOpc.dll to repair connection to OPC server. It may be done as a custom development.
Rapid SCADA does not know that the OPC server has been shutted down
It’s true. There is a workaround. You can send a command via a text file to restart the communication line:
Create a file cmdXXX.dat within C:\SCADA\ScadaComm\Cmd
where XXX is a random number[Command] Target=ScadaCommSvc Sender=ScadaCommCtrl User=Admin DateTime=12/21/2015 23:00:13 LifeTime=60 CmdType=RestartLine LineNum=1 End=
I think you can create a file by using formulas in the configuration database (Administrator app).
Hi,
Thank you for the details.
You should understand how the data are encoded when you send the command 0x10 (Write Multiple Registers):
You can choose either:
1. Binary command. Using this option you can explicitly specify the bytes which are sent. Let’s try it.2. or Standard command. See these lines:
modbusCmd.Data = cmd.CmdTypeID == BaseValues.CmdTypes.Standard ? BitConverter.GetBytes(cmd.CmdVal) : cmd.CmdData;
The value 14 is 0x402C000000000000 when converted into a double (see this). Then you send the 4 bytes from the right that are zeros.
You can create formulas in the configuration database to convert data entered by a human to the format described above.
I validated the packages by http://modbus.rapidscada.net/ They are wrong. Communicator never sends wrong requests.
Could you provide screenshots?If you need to send float, you need at least 4 bytes to store it. So you can’t use Write Single Register command which sends 2 bytes.
