1) Ensure that the programmable input is not set to Motor Set Select
before using this function.
2) See the relevant soft starter manuals for a complete parameter list.
The first product parameter is always allocated to register 40009. The
last product parameter is allocated to register 40XXX, where XXX =
008 plus total number of available parameters in the product. The
Modbus TCP Module can read or write a maximum of 125 registers in
1 operation. These registers support multiple write (Modbus function
code 16). Attempting to write a single register returns a fault code 01
(illegal function code).
