I’m familiar with .NET so driver that decomposes events is a good option.
Should it be a class derived from DevModbusLogic?During SCADA running, I can polling the counter for new events (separate register 0x0500) and read as many as occurred.
After a restart, I would have to read all the events that I did not save in the database to archive the full history.I’m not sure if I can make it with Automatic Control Module.
This device has a register range for events, which is a circular buffer.One event is written in 8 registers:
0 Event code
1 Value: Lo(Int1), Hi(Int2)
2,3 Value float
4 Lo(month), Hi(end of year)
5 Lo(hour), Hi(day)
6 Lo(second), Hi(minute)
7 millisecondsThe last event is under 0x1000, the pass under 0x1008, and so on.
I would like to save all events in the database and present them in a view already from the database. I think this is the easiest way. The complicated part is reading from the device and storing them in the database.
Hello,
Thank you for your advice.
I will check if reading from one address is enough.
I will also try the Automatic Control Module and come back with any further questions.Got it!
It was the LAN port. I have used the second one for the connection.
After replacement of the port I can connect.Thank you for your help!
@odobrev
Thanks again!Unfortunately I can not establish the connection with an error in line log: “No connection could be made because the target machine actively refused it”.
Probably some network setting are wrong. I am doing it on fresh Windows 11 VM, firewall is completely disabled. Adresses are ok, I can ping and log in via browser into logger interface.
I tried Modbus TCP settings with Link setting Limited and IP address as you mentioned also with unlimited access.
What are your Modbus TCP settings on the logger?
Address mode Logical/communication address
Logger address
Fast schedulingDo you use LAN or WAN port on the logger?
No problem, thanks!
I’ll try it out right away!Hi,
sorry, the question was addresserd to @odobrev.
He said, he will provide some example config to Huawei device which I try to connect via Modbus TCP.Hi,
Are you already back from vacation and could you help with MODBUS TCP configuration. I’ve run SmartLogger and enabled ModBus, but I’m having trouble connecting and thought I’d wait for a sample configuration.
Best regards
