emulation properties.PNGim tryna connect an arduino uno as modbus master to my flexsim model which is the modbus slave via a RTU (serial connection) and when programming by arduino it says Modbus holding registers are from ox40001 and up but on flexsim it says registers go from 0-9999 so wondering how these flexsim registers worked in relation to standard modbus registers. does this mean register 1 is ox40001?
