Show in Figure 2-3 is of the IED structure diagram, using V-RTU2000
as well as the IED equipment. There are two independent
communication channels are provided by V-RTU2000 CPU Card, of
which, one links to the host computer. The other one links to the
Power Meter or IEDs for obtaining I/O information for such equipment
and also transferring the Output control command. In addition, the
V-RTU2000 also provide I/O cards (AI, DI, AO, DO and etc.) to
collect the field information and also carry out the Output of control
command.
