Modbus use of preset holding register (function 0x10)

[charlyprouteau]

Dear sir,
I use modbus master controller.
I would like to write some UINT16 with function code 0x10.
For example, I would write 5 UINT16:
40001
40002
40003
40004
40005
When I modified the value of each register, each register are sent one by one :
one request per register with function code 0x10. I also tryed to modified the register values by Scripting but same result.
I can use UINT 32 to send two registers but how can I do to writemore than 2 registers.
Regards,

You can force code 0x10 using this option in the Modbus Master Settings.

Please note: Writing INT32 automatically forces 0x10.
