It depends on the protocol, connected to this port - Look in the document 3BSE035982-510_en_AC_800M_5.1_Communication_Protocols
Please note - without converter, only 1 RS232 device to COM3 (point-to-point) !
COMLI - with RS232/RS485 converter - max 31 slaves; The maximum message size is 512 bits or 32 16-bit registers (integer reading).
