d) Interfaces and Communications
The DFF has two communications ports. The front port is RS232 while the rear port can be RS232, RS485, plastic
or glass fiber optics.
The DFF associated software is the following:
•
Communication software GE-LOCAL, that allows the user to view and modify the protection settings, alarms,
internal status etc.
•
Configuration software GE-INTRO, that allows the user to configure the inputs, outputs, alarms and LEDs.
•
Oscillography software GE-OSC, that allows the user to view and analyze waveform captured data.
These software packages are integral part of GE-NESIS software (General Electric NEtwork Substation
Integration System).
