Writing problem in MODBUS with profile - Juande - 08.01.2024
I have a problem with modbus function 16, reading works perfectly through the profile, but I can only write through the lua script. With this script I can write:
Code:
require('luamodbus')
mb = luamodbus.rtu()
mb:open('/dev/RS485-1', 9600, 'N', 8, 1, 'H')
mb:connect()
mb:setslave(20)
mb:writemultipleregisters(20, 1)
mb:close()and this is the profile I use:
Code:

}Please can you tell me where the error is?

"inputregister" is read-only. Change type to "register" in mapping entries that should be writable.

ok, thank you very much, it works now!!!
