FOUNDATION Fieldbus: Control in the Field Helps Nicaragua Achieve its Aggressive Renewable Energy Agenda

Having been awarded the concession for a geothermal field in Nicaragua, US geothermal power specialist Ram Power and their design engineer POWER Engineers evaluated the available technologies and opted for a standard control system to be located centrally in the control building. The decentralized field devices (e.g., pressure and temperature transmitters and control valves) at the San Jacinto Steamfield are linked to the central controller over a FOUNDATION fieldbus Modbus over Ethernet gateway. The project team of Ram Power selected the Softing FG-110 FF gateway to link the field devices to FOUNDATION fieldbus technology. In using this approach, Ram Power was able to exploit the advantages of FOUNDATION fieldbus Control in the Field (CIF) to implement the required control loops, thereby moving the actual control function from the control room to the field devices.
