MikhailModeratorHello,
To find the cause of the issue in the modified module, debugging is needed. This is not included in free support. You should debug the modified module by yourself or wait for a release of the new module version.
MikhailModeratorHi,
I agree with the point of view that a process should not depend on computer in any case. All critical tasks should be managed by PLCs.
Talking about SCADA redundancy, a custom development is needed to implement it as described. Otherwise, use 2 parallel independent communication lines.
MikhailModeratorHi,
In the debug log I see some channels with >50% empty rate, those channel have signficantly less data in database analysis. While the graph in RS webstation shows complete dataset for these channels.
Could you provide data examples?
Will the new plugin be pushed to scada git repo?
Yes.
MikhailModeratorSomething like
insert into mytable field1 values (@cmdVal)A command contains only one value.
You should try. In case of errors, you could send links to screenshots and post logs.
MikhailModeratorHi,
What is the source of the text “The standby server does not duplicate the primary server’s functions…” ?
To implement the described mode, there should be a separate supervisor service that switches servers. We can develop it if needed by a custom contract.
MikhailModeratorHi,
We will release a fully new ModDbExport which can insert several channels in a one SQL request. My suggestion is to wait for the release.
MikhailModeratorHi,
Currently there are the following options:
1. Manually start and stop Communicator services on the servers.
Data transfer can be performed by Rapid Gate module.2. Use 2 servers in parallel. Both of them poll the devices. To do that, you need a hardware gate that allows multiple connections. Like Modbus TCP gates.
In the future, switching logic may be implemented by Auto Control Module be sending start/stop communication lines commands.
MikhailModeratorI suppose, the default event panel is meant.
@123abc56 , thank you for the ideas. Will see what we can do in v6.
MikhailModeratorThere is also ModDbExport module. You should compare it with KpDbImport.
MikhailModeratorMicrosoft SQL Server definitely provides a current time function. You should google it on database forums.
If you use KpDbImport for sending commands, it supports @cmdVal and @cmdNum parameters of the SQL statement for command value and command number.
What is the generalized task you need to resolve?
MikhailModeratorHi,
Please provide detailed requirements for redundancy that you need.
MikhailModeratorHello,
What module of Rapid SCADA do you use to execute this SQL request?
What DBMS type?
MikhailModeratorInteresting. Is the C# library is fully written in C# or just a wrapper for C library?
GPL requires you to provide the source code of your driver. If you do this, I suppose it’s compatible with Apache-2.0.
MikhailModeratorHi,
The KPLogic class contains AddArcSrez method. The example is here
Do you use some library that implements IEC60870 or implement the protocol from scratch?
MikhailModeratorNearly 90% of devices are using Modbus Driver,and another is OPC UA.
Good.
You provided the Communicator log. What is in the Server log at the same moment when a problem occurs? -
