Hi,
The log says that there are problems with a converter:
2019-06-17 17:00:23 Open serial port COM4
2019-06-17 17:00:23 Error executing the communication channel actions before session with a device: Error opening serial port: Access to the port ‘COM4’ is denied.Hi,
Rapid SCADA works as TCP client, not TCP server. It connects to a PLC which is TCP server and PLC keeps port 502 open.
Hi,
1. Please clarify the question.
2. Do you mean using real devices or simulators?
There are 2 videos where shown how to simulate a Modbus RTU and OPC connected device.
It would be better if you provide a diagram of your system.after about 4 hours a first queue overflow alarm is coming out
A long time needed for exceeding the queue size means that simple increasing the queue size doesn’t solve the issue.
you should have my email where to write your offer for remote
Please send email again to let me identify you correctly ))
Your description is clear, but watching the process is more efficient.Hi,
Likely the queue size is exceeded because of the error executing the request. What is the full situation in logs currently?
I could connect to your machine remotely and research for the cause, but this service is out of free support.This is strange, because there is no column named “Infinity” in your SQL requests. Do you have any idea where you can mention “Infinity”?
Also ExportEvents tag contains false that means that “Error export events” should not be printed in any case.
May be another configuration is running?
Hi,
Table views uses hourly data.
If you’d like to watch minute data use Minute Data Report or Chart Pro Plugin.
