# Virtual I/O Mode

An RIO900 can be configured for Virtual I/O Mode where Modbus Registers of the RIO900 are mapped to I/O values of Virtual Output Modules as shown in Figure 3b. In this mode Remote I/O is mapped to predefined Modbus Register space in the target. This enables Modbus Masters such as an RTU/PLC Master or SCADA Master to use I/O points from an RIO900 based I/O telemetry System without connecting to actual I/O (Figure 3a) . This saves on wiring and I/O hardware costs.
