PROTOCOL-SPECIFIC INFORMATION
2. Implement one single Modbus read transaction, starting at register 201 for a quantity of 54 registers.
Then, pick out the registers of interest and ignore the rest of the response data.
While both of these methods will certainly work, neither one of them is optimized for the task at hand,
which is to access three specific register values. A fully optimized solution can be realized by making
use of the register remap objects. Non-contiguous inverter registers can be grouped together in any
order and accessed efficiently via the Modbus/TCP “read multiple registers” and “write multiple registers”
function codes. The net effect is one of being able to transfer larger blocks of registers using fewer
Modbus transactions, which results in improved network utilization and simpler data manipulation code
on the Modbus master device.
Description
This 32-character (max) field is strictly for user reference: it is not used at any time by the driver.
Remap Register
Remap register that maps to the specified inverter register. Select from 2001 to 2050.
Register
Inverter register (refer to section 4) that is accessed by the Remap Register.
Data Type
Fixed to 16-Bit Unsigned. This is equivalent to two bytes.
