10. Interface definition Modbus RTU

SIRAX BM1450 supports Modbus RTU protocol (RS485).
The permissible address range for the BM1450 is between 1 and 247. Broadcast Mode (address 0) is not allowed.
The maximum latency time of an BM1450 is 200ms i.e. this is the amount of time that can pass before the first response character is output.
After sending any query through software (of the Master), it must allow 200ms of time to elapse before assuming that the BM1450 is not going 
to respond. If slave does not respond within 200 ms, Master can ignore the previous query and can issue fresh query to the slave.

10.1 Modbus functions

Following code functions are provide:

Function code Function

Address

03

Read holding registers

40001 to 40079

04

Read input registers

30001 to 30231

16

Presets multiple registers

40001 to 40079

The slave only answers Modbus requests with a valid parity and correct checksum. The slave responds with the following exception codes (0x80 + 
function code) to requests with unsupported functions, unimportant data addresses or invalid data values:

01

Illegal function

The function code is not supported.

02

Illegal data address

Attempt to access an invalid address or an attempt to read or write part of a floating point value.

03

Illegal data value

Attempt to set a floating point variable to an invalid value.

Access to 3X and 4X registers for reading measured values

Example:  Current Ch 2 from 3X: 

Start adress = 00 04 

Number of Register = 02

 

Power Ch 1 from 4X: 

Start adress = 10 0A 

Number of  Register = 02
