ORSO2001 Posted January 31, 2019 Report Share Posted January 31, 2019 Dear All, for my next project I have to manage a ModBus RTU data exchange with 57 devices by RS485 port...but the system can be enlarged in the future...where the Unistream works as master. two of these devices has the same ID 49 and it is fixed and is not possible to change...in the others can be selected. one port is already present in the PLC; I know that exist the external module (UAC-02RSC) to have +1 RS485 and +1 RS232...but it would be nice have a module to have +2 RS485...exist a way to have this withou buy 2 x UAC-02RSC to have 3 x RS485? thanks PS: can be a solution connect a converter RS232/RS485 with the module UAC-02RSC or some problems can arise?
