The virtual I/O function performs the following. Inputs the result of the output from the MFDO terminal to the MFDI terminal without external wiring. Inputs the result of the output from the MFAO terminal to the MFAI terminal without external wiring. This can simplify the external wiring and reduce the cost. image/svg+xml Warning image/svg+xml Sudden Movement Hazard Before you do a test run, make sure that the setting values for virtual input and output function parameters are correct. Virtual input and output functions can have different default settings and operation than wired input and output functions. Incorrect function settings can cause serious injury or death. Figure 1. Virtual Analog I/O Functional Block Diagram Figure 2. Virtual Digital I/O Functional Block Diagram Note: Refer to H1-xx Multi-Function Digital Input Setting Values for more information on the virtual digital input setting values. Refer to H2-xx MFDO Setting Values for more information on the virtual digital output setting values. Refer to H3-xx Multi-Function Analog Input Terminal Settings for more information on the virtual analog input setting values. Refer to H4-xx H4: Analog Outputs for more information on the virtual analog output setting values. You cannot set 0 [3-Wire Sequence] and 20 or 2F [External Fault] to H7-01 to H7-04 [Virtual Multi-Function Input 1 to 4]. When you will not use the terminal, set H7-01 to H7-04 = F. The through mode function is not supported. You cannot use the virtual I/O function selection and the multi-function input for DI-A3 at the same time.
