That is what IDEs should help with.
They will write all of that boiler plate for you.
The new AI generators might help, too. I have not used them directly, but I have watched team mates flounder trying to have AI generate simple commands that I was able to find in the man page.

I mean, I think it would be better if the boilerplate didn't have to exist, if possible, simply because even if generated, it still creates a maintenance point.
If some of the boilerplate were baked in as language constructs, or if the language was extensible, you could eliminate that boilerplate at the last mile .i commented to some others here giving an example that a library couldn't solve in C#, but the IDE approach, while it would solve it and does, even with like Winforms tech and InitializeComponent(), now you have InitializeComponent() to maintain. Not the greatest example because it round trips from the designer but most of the time with most tools that's not the case.

The product is expensive, but I haven't seen anything to compete with it, and I need the ability to sniff MODBUS commands and responses on a RS-485 bus, interpret them correctly, and save them to a log. This item looks like it will do the job, but it needs to be connected to a PC to perform. I'm thinking I can build or buy a single board computer small enough to be deployed in the field inside a weather-proof box for a week or two to search for missing commands or spurious ones. It would be very helpful to hear from previous users, though, before I embark on this course.

I haven't, but they do have a forum which might be a good place to duplicate this request?

Interesting, but as with most MODBUS products, it wants to be either a Master or a Slave. I just need to log everything on the bus.

Nice system! If I was working on developing devices it would be very helpful. But I need something I can hang in a cabinet in the field and let it run. I have a solar array (840 kW) connected to a battery (1 MW / 2 MWh), both controlled by a Site Controller. There have been some anomalous events over the past few months, and I suspect communications issues. With 14 inverters, three diesel generators and one big battery, it's hard to isolate which unit is having problems, especially when I can't get confirmation that the controller even sent the proper commands! Seriously, who would build a system controller that has no logging capability? I expected better of Tesla!

You *could* in theory make one of these. I'm not sure what it costs, but if it's expensive and you're not sure you could produce one yourself with some work.
I made something similar, but it was simply for a basic serial UART, not RS-485.

You could adapt code like that using code like this:
GitHub - zivillian/esp32-modbus-gateway: ESP32 Modbus RTU/TCP Gateway[^]
Just a thought, even though it may not be realistic for you. I'd do it, but then I'm a bit crazy.

I was thinking something like passing it through a pi kind of akin to a proxy. Just echo the traffic out the other side.
A simple device to do only that might have market because splitting it means you could have the traffic sent to logging and the device, or maybe to a 'real device' and also a device under development/testing.
They build something like this in a pizza box rack mount style, though I don't recall what it was called. PC feeds all serial to it and it then feeds the serial wherever you configure/connect it.

I would use a realtime MCU rather than a Pi for that. I just don't trust what is essentially a tiny PC to have the regular latency to keep a clean, uninterrupted signal. It probably will, I'm just paranoid. Part of it too is I think an RPI would be overkill when a cheapo ESP32 could easily handle it.

Yeah, it'd definitely fail from what I get about all this. But temp diagnostic tool vs production component maybe?
Sounds like it'd be just plug it in and capture the broadcast packets and throw them on disk. At least that way failure just means losing the logging you had it doing.

There is no need to pass data through it at all. All that does is unnecessarily add another potential point of failure. This is RS-485 which is inherently multi-drop so it would be much better to have a listen-only device.

I dealt with MODBUS 30+ years agoβ¦ I donβt remember it having checksums/CRCs/hashes.
Or is that covered on the wire protocol?
Put large, power conditioner capacitors on all electric supplies?
