Re: [AFMUG] Modbus

2023-10-26 Thread Adam Moffett 
That line from the vertiv manual is so cryptic.

If the there isn’t a standard set of registers for this purpose then there must 
be a specific AC meter it supports.  I don’t see one on the listed accessories 
in the literature though.

Meanwhile the same manual has explicit instructions for setting up to get data 
from a particular brand of battery controller with modbus.  On the topic of AC 
meters I just get, “oh yeah we can meters with modbus.”

I did send a message to support.  I’ll bet $5 they don’t know either.

Thanks for all the info everyone.

Yes, and no.

The modbus protocol defines how to move data between two devices.  However, the 
contents of the data being passed is vendor-defined and there aren't any 
industry standards I'm aware of (although it wouldn't surprise me if there 
were).

Every vendor that produces a modbus-capable device usually publishes some sort 
of guide to the modbus registers for each device.   For instance, a quick 
google search turned up this document:

https://www.vertiv.com/4ac5f2/globalassets/products/monitoring-control-and-management/monitoring/modbus-protocol-for-bdsu-reference-guide.pdf

"modbus register map" or "modbus communication guide" or simply "modbus" when 
added to your vendor or product name often will turn up the right document.

Just FYI, A couple of years ago, I would have suggested you provide me with the 
vendor of the equipment, and I'd make you a firmware load for the sitemonitor 
serial module to be able to read this, but that codebase needs to be re-written 
to support the base 3.   At some point in the future I'm going to resume doing 
those requests in which case you'd end up with a module which pulls data from 
this device.   Doesn't help you right now though.

Modbus is an ancient serial protocol to pass values back and forth.   It’s very

Tons of information online, and it’s not a hard protocol to code for.   Used to 
do it in BASIC years ago. There are two protocols - MODBUS and MODBUS RTU.  
 The RTU protocol is much more difficult to work with due to timing

of responses is not critical at all.

There are modbus libraries in at least "C" to read devices...  I read
