Hi all,

i'm using a Dixell XC645CX regulator for compressor control and i need to connect it to main bms.

i would need modbus register for this regulator so if anyone has it...

thank you in advance

 

This is what I received from Dixell Italy.<pre>

The information Dixel have provided has the Modbus address for each element it supports. You just need to read it carefully as there is no delimiter in the test. Example above could be read as follows:

Name: Suction SEtC_C/bar
Read Register: 0381(hex) or 897(decimal)
Num.Elements: 0001
Read Write Register: 0381(hex) or 897(decimal)
Num.Elements: 0001
Write: 1
Gain: 1
Dec Offset: 0
Unit: °C
Byte Order: H-L
Format: 16-bit Signed
R/W: R/W
