Modbus profiles examples

[Dré]

LM does not have D0/D1 markings, but A/B/GND. A is positive, B is negative. Try swapping A/B lines and also check that the serial port settings match.

now the communikation works!

I´ve found the manufactur manual with chapter 9 (Communication with Modbus) inside.

Here are the fields: Quantity, Details, Start reg (hex), Size, Res., Unit, Data type,

for Example:

Quantity: Active import, Details: Tariff 1, Start reg (hex): 5170, Size: 4, Res.: 0,01, Unit: kWh, Data type: Unsigned

When i try reading Active import with these settings:
- Function: Holding register (#3)
- Address: 20480
- Data type: uint64
- Read swap: Word

the Answer is 94425 (i think its 944,25 kWh), that is correct.

but how i have to "translate" for the Logicmachine? I know, that i have to calculate hex into dec (like 5000 in hex is 20480 in dec). In the Modbus Profile Generater are Fields like bus_datatype, datatype, value_custom, read_swap...

Can you give me an example? Thankx

I have the ABB B21 and have the next script what is working, maybe this can help you?

}

The last read_delay is because is had 2 devices and the next device i activate didn't work
