Virtual Inputs; Virtual Outputs - GE Multilin W650 Instruction Manual

5.6 INPUTS/OUTPUTS
Virtual inputs are signals that can be written directly via communications. Their status can be established as ON (1) and
OFF (0), through writing by communications using EnerVista 650 Setup.
The change of state of virtual inputs is made according to their type. Latched virtual inputs remain at the set value until it is
changed by communications. Self-reset virtual inputs are activated by writing, and they remain active during one cycle.
There are 32 virtual inputs of each type.
5.6.7.1 VIRTUAL INPUTS WRITING:
Setpoint > Input/Outputs >Virtual Inputs for activating / deactivating signals
To write a virtual input, select the virtual input to activate clicking on the virtual input checkbox, then press on the store
button and virtual input will be written to the relay (see Figure 5–32: ).
If it is a self-reset one it will remain active during one PLC cycle and after that the virtual input value will be cleared.
If it is a latched one, the value will remain active until it is cleared by the user, clicking again in the virtual input
checkbox and pressing on store to clear the value.

Table 5–85: VIRTUAL INPUTS STATUS
Text assignment for virtual input is made at Setpoint > Relay Configuration > Virtual Inputs. It should be taken into
account that the text assigned for virtual inputs in the relay configuration screen are only for file management, they are not
sent to the relay.
There are 512 virtual outputs that may be assigned via Logic configuration. If not assigned, the output will be forced to
.OFF. (Logic 0). An ID may be assigned to each virtual output. Virtual outputs are resolved in each pass through the
evaluation of the logic equations. For more detailed information see chapters 5.8 and 5.9 in this manual.
