Modbus RTU protocol & registers
Modbus message
Following the ModBus protocol standard requirements, it is possible to write and read the E9T control unit
registers in order to configure parameters, perform functions and check the device status in real-time operations.
Standard Modbus message for the E9T devices
Device Address
Comprises between 1 and 127
. The “0” value is not permitted.
Func ID
Func 03 (Read Holding registers)
Func 06 (Write Single register)
Data
The E9T register (AND value if writing a register) ;
CRC
The cyclic redundancy check is calculated following CRC16 algorithm criteria.
E9T Modbus registers
The complete list of E9T Modbus registers is listed below. In the access column R means that the related register
are read-only and R/W means that the related register can be read and also written.
