  • Page 57: Virtual Port Group Function

    Features and Functions Virtual Port Group Function The U2600A series DIO modules allows you to randomly select any eight input bits or output bits and group them into one channel as a virtual DIO port. You must select exactly eight bits to group them to a virtual channel.

  • Page 58: Interrupt Function

    Features and Functions Interrupt Function This feature is available for the U2651A and U2652A. There are two interrupt sources for the interrupt function, which are bit 301 and bit 302 located at input channel 101. They are actually physically sharing the same bit with bit 101.0 and bit 101.1.
  • Page 59 Features and Functions The Enable Register acts like a gate for the Interrupt Operation Register. If the Event Register is not enabled (i.e. gate is close), the interrupt signal will not be sent to the Status Byte Register. If the Event Register is enabled, the interrupt signal will be sent to bit 0 of the Status Byte Register.

  • Page 62: Trigger Function

    Features and Functions Trigger Function The major difference between interrupt function and trigger function is that after the user selects any trigger source, the IO operation will be frozen. In other words, the output will stay at the previous stage and the input reading values will also be frozen.
