Modbus Multiple Write Problems (write_multiple=true)

[Juande]

Modbus has two different functions for writing a single or multiple registers. Certain devices don't support single register write so write_multiple tells to use multiple register write command for a single register. It will still write only one register, not multiple registers at once. You can use a script to write multiple separate registers in one request.

Okay, thanks!
Is it better to use the profile for reading and writing single records and Lua for writing multiple records? Or should I do everything from a Lua script?
