Add calculated channels to OPC UA Server

[odobrev]

@oley Oh and also, pay attention to Smart Logger ACL Security.

In Smart Logger Modbus TCP settings, you either need to disable ACLs or add your IP adresses to Client list (limited to 5 in Smart Logger 3000).

—
Link setting : Enable (limited)
Client 1 Ip Address : Your SCADA PC or Server IP
Address mode : Communication address
Logger address : 10

At least these settings work for me.

Also be aware that Smart Logger has a dynamic mapping by inverter that needs to be calculated from the inverter modbus starting address.

It’s in the documentation.

I had 3 inverters starting from 12 so my config file is based on this.

@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 scheduling

Do you use LAN or WAN port on the logger?

@oley

I did not configure the logger myself but from what is configured in my interface in Wired Network is :
—
— Wired Network
WAN/LAN port working mode : WAN+LAN

— WAN & SFP Port Parameters
DHCP : Disable
All static IP fields and dns are set with the IP I’m using to connect to the logger.

— LAN Port parameters
Static IP set to some unknown IP that I’m not using and the cable is not pugged in.

As for Modbus TCP settings, I already mentionned it before :
—
Link setting : Enable (limited)
Client 1 Ip Address : Your SCADA PC or Server IP
Address mode : Communication address
Logger address : 10

As for settings in rapid scada communicator, you have it all in github screenshots folder.

@odobrev

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!

@oley

Glad I could help you.

Don’t hesitate if you need more info.

Now you’re in the fun part, adapting register configuration to your needs, testing and UI implementation…

Took me two weeks because their documentation often mentions registers that are not readable depending on your configuration or system.
The sad part is that not everything is available in the MODBUS Interface of the Logger, you’re short of a lot of detailed variables that you get from directly using Inverter Modbus Interface. If I had a choice, I would’ve used another generic gateway such as Moxa branded ones (they’re fantastic) for each inverter to get all the variables.
