6.4.5 I/O BOARD STATUS
Actual > Inputs/Outputs > I/O Board Status
This screen is used for verifying the status of I/O boards. If all the I/O boards, one (F) or both (F and G) depending on the
relay model, are correctly inserted in their tracks and are in good state and communicating through the internal CAN Bus,
the green LED will remain lit.
I/O boards accessible through the external CAN Bus are labeled as H and J. In order to start working with the external I/O
boards is necessary to select the appropriated I/O board type for each slot (H or J for the CIO module) at
Setpoint >
Inputs/Outputs >Contact I/O > Board H and J
. Otherwise the relay will not start communicating through external can to
the related board.
If one of the boards has been extracted, or the relay model does not match the installed hardware, the corresponding LED
will remain unlit.
Table 6–49: I/O BOARD STATUS
For all I/O board screens described above, the last LED provides this same information individually.
6.4.6 VIRTUAL INPUTS
Actual > Inputs/Outputs > Virtual Inputs > Virtual Input Latched > Virtual Input Self-Reset
“Virtual Inputs” are signals transmitted by communications. The EnerVista 650 Setup provides a tool to set virtual inputs
through ModBus at
Setpoint > Inputs /Outputs /Virtual inputs
that is only available in on line mode (communicating to the
relay). There are two available groups of 32 signals each: Latched inputs and Self-reset inputs, and all of them can be used
internally to perform operations, new logics in the PLC, etc.
In this actual values screen the status of the assigned virtual inputs can as shown on Table 6–50:
Table 6–50: VIRTUAL INPUTS STATUS
6.4.7 VIRTUAL OUTPUTS
Actual > Inputs/Outputs > Virtual Outputs
This screen provides the status of the 512 configurable virtual outputs (internal variables) used in the logic scheme. The
virtual outputs are set from 000 to 511.
The configuration of the logic associated to the virtual output is in the
Setpoint > Logic Configuration
tool provided by
EnerVista 650 Setup program.
