You can use this simple utility for testing. Also try 3rd party OPC clients, such as Matrikon OPC explorer and Prosys.
Hi,
I cannot find the above lines in scheme-render.jsThe above is a good example of what I was saying.
Also you can try to set an archive option to write data on each change. But it may require a lot of disk space if data change too fast.How do I make the LED indicator condition show green when no alarm, and red when alarm is on
Open the Conditions property of the component and change the colors.
For example, the device returns a list of registers A1…A10. And a manufacturer says that this is an array. A driver should create a tag that has length > 1 to support an array. But the current Modbus driver does not support this.
While OPC devices can return data of array types. And the OPC driver also supports this.
Hello,
OPC UA driver in Rapid SCADA 6 can read arrays from the OPC server. On SCADA level each array element is stored in a separate channel. It’s easier to try and watch how it works.
Yes, event has it’s own timestamp that equals to an event creation time. While archive timestamp may be different if the archive uses a writing period. But 20 seconds difference is too big if the archive period parameter is 1 second. I would be OK if the archive writing period is 1 minute for example.
Hello,
If I understand you correctly, the channel 5767 (Output) was created to set the value of the channel 5567 (Calculated).
Try disabling the channel’s 5567 formula. Commands should work in this case. Next, you need to fix CKLP. Could you describe how CKLP should work?
Hi,
May be you need to install OPC Core Components (available on our website).
Also, you should configure access rights in DCOM settings, which can work unpredictable.
OPC DA does not need to specify TCP port.Consider installing the Communicator service on the same machine as OPC server. Communicator can send data to SCADA-Server remotely. And configuration may be simplified.
The examples were added. Check this link.
Hello,
The existing OPC DA driver (DrvOpcClassic.dll) does not support the OPC XML DA standard.
In my opinion, OPC XML DA is a transition standard between OPC DA and OPC UA, so the standard too rare to implement its support.
