A CLASSIC PRODUCT ADDITION ???

[boB]

in addition to the above questions,

Do the hawksbay and barcelona also use modbus to communicate?

No, they use Canbus

[Barry Fields]

Do they use something different than MNGP or just a different version of MGNP?

[boB]

MNGP2  which is CAN

Completely different than the MNGP

[Barry Fields]

MNGP2  which is CAN

Completely different than the MNGP

Sooo It would make sense if we wish to use BBMT on classic 150 or Hawksbay, it should have both modbus and Can capabilities.

BBMT ?

BBMT ?

from a few posts back
First we need to name this potential new product. I would suggest BBMT (Barry's Better Mouse Trap).

Is my security clearance high enough to ask what MCU is used in the Hawkesbay and Barcelona ( I presume they are the same)?

[Barry Fields]

More stuff I do not know:

In the Classic is the battery voltage stored in a registry as a 10bit value?
Could a more accurate 12 bit value be stored and processed?

In general if you wanted an MCU to be able to communicate with either modbus or canbus, can that be done with one bridge and one r485 connector or would you need two?

They are ARM Cortex-M3  parts from NXP.

Most values are stored as 16 bit words.

Not sure of the A/D word size.  Either 10 or 12 bits.

Am I correct in that mcu is limited to 8adc channels (4 differential)?

In which case maybe STM32F030 might be better suited with "The 12-bit analog to digital converter has up to 16 external and two internal (temperature sensor, voltage reference measurement) channels and performs conversions in single-shot or scan modes. In scan mode, automatic conversion is performed on a selected group of
analog inputs.

That would allow for 4bank monitoring (uses 8 channels) plus Remote Battery Sensing (1 input).

I am still learning.

It is best that I drag this all together in an illustrative format.  Most all the proposals have been discussed in detail in a myriad of posts over the last year or so.

I am indeed open to answer any questions?

I want to express my thanks to many of you for your patience and cooperation.

I have a friend who uses PLC to do things like you have drawn up. It can read modbus and sensors and has built in relays and logic , etc.
I don't know PLC's but have messed around with Node Red a little bit which can do all by running on a Raspberry Pi or PC . There is no end to the coms , inputs , outputs, of any type with Node Red. But I am no expert in that - just know the basics .

Pause for reflection:

Is there anything I have suggested that:

1) "could not work"?

2) That would require any modification to existing MidNite charge controllers except maybe a firmware upgrade?

3) That would not add to or improve the capabilities of MidNite charge controllers?

Any positive or negative feedback would be appreciated.

Barry, let's see your idea of a phone app and how it would show data

That's what people want
