On Raspberry, I used formulas to save and read channel data to a file. Since the values fall into RAM (tmpfs)
Насколько знаю, это доступно только пользовательским командам протокола, которых нет в драйвере. Так что не совсем ясен сам вопрос ?
з.ы. а почему на английском сайте ?Redirection was enabled by the site owner on the apache stub page, so it shouldn’t happen by itself 🙂
This means that when we open the root of the site, the Apache page should open and not jump to the internal site. It is not clear why this is happening ?
Thank you, it works. But there are nuances 🙂 For example, if you write the root of the site mysite.com then there is a redirect from the apache page that should not be, is there any way to fix it ?

I used port 8084. Michael needlessly removed the settings for mono-xsp4 from the installation description file for the mono version
Maybe the address is not 5 ? And this address is listed in the documentation as an example, if the device has an address of 5 ? Or maybe someone changed the address in the device ? The same baud, parity, bit depth ?
Changed it to Port 23 and no difference. ????
You have a different port specified in the Ethernet settings-RS485 and it must be specified in the communication line settings. It is the one that is registered as Local Port Number and not 502 or 23 by default
In this case, the Modbus device settings should be as for RTU mode-TransMode = RTU
Try reading just one register first and make sure they are readable. and only then add registers to the query group
Why are you using port 502 ? after all, by default, the device Ethernet-RS485 has port 23 when it is configured as a tcp server ?
You have a simple interface converter, not a protocol converter. You configure the communication line as a TCP Client by specifying the IP and port. Scada is configured to work with the RS485 interface. transmode = RTU Address = 5 do not specify a Call Number, leave the field blank
Does your converter convert the protocol from Modbus TCP to Modnus RTU ? or is it just an ethernet – rs485 interface converter ? If the latter, then set the transemode RTU mode and remove the callnumber leave only the IP and port communication line settings
If the Denian system is similar and there is enough space to install Mono, it is quite possible. Mono uses a lot of space during installation.
I don’t use a MAC, but Mono is present on the site for this environment as well.

This means that you can run it on macOs, but the startup scripts will need to be reworked, since macOs is based on a BSD system, sort of.
