7.1. COMMUNICATION PROTOCOL - MODBUS RTU

*Address of module 0x01

Operational parameters of communication line  RS485 MODBUS (RTU):

9600Bd
1 start bit 
8 data bits         
1 bit even parity 
1 stop bit
Each module must support even parity. If parity is not used, it is replaced by second stop bit.

Communication method:

Master – control system (BMS)
Slave – electronics Module D (Modbus module)

Only the control system can be connected.
After the first connection of power supply, the module is in the OFF state. The requested operational mode must be sent by the superior control system! After 
the subsequent disconnection of the power supply, the module remembers its last operational mode.

Communication connector numbers:

A - 6
B - 7
GND - 8

MODBUS RTU:

In the RTU mode, every 8-bit byte of message contains two 4-bit hexadecimal characters. The   transmission of a message must be continuous, the spaces 
between the characters must not be longer than 1.5 character. The beginning and end of the message is identified according to the bus rest longer than 3.5 
character. The RTU frame format is shown in the picture.

Address 

Master has not any specific address, only slave units have to have an address unique in all MODBUS site.

CRC

Field with generating polynom x16 + x15 + x2 + 1.
