Hi Edilberto. That VI configures input and output subsystems.
State: Turns the electronic load input ON or OFF. When input is OFF, the electronic load will draw minimal current at its input. The state of INPUT OFF overrides the state of SHORT ON. The presently programmed slew rate setting is not used when turning the input on or off; the current and voltage change at their maximum rates.
Short: This control applies the equivalent of an electronic short across the input of the electronic load. The actual condition of the electronic load under a short condition depends on its operating mode. For details, refer to Chapter 4 of the programming manual.
Protection Clear: Resets the electronic load latched protective features( such as over voltage, over current, overpower, etc.).
If a trigger is received during the time a protection circuit has shut down the input, any triggered levels are stored and will be transferred to the main level after the protection is cleared. Triggers received during protective shutdown are also applied to the Transient subsystem.
Output: Controls the general-purpose digital port on the rear of each electronic load or each channel of the multiple electronic load. The state of the port is with respect to the common side of the electronic load input. Setting a port to ON state disconnects it from common and sets its to a TTL logical high.

By the way there are forums in Spanish available now
