UniConnThe UniConn universal site controller provides a single platform for protection, control, and data acquisition for ESPs, surface pumps, or other monitored wells. Applications Fixed-speed and variable-speed motor control and protection n Surface data acquisition for monitoring downhole gauges n Wellsite interface for all artificially lifted and monitored wells n Benefits Ultimate control and data management to help protect well or reservoir system’s investment n Simple field operation and maintenance to reduce equipment and training costs n Proven reliability and integrity in most environmental conditions n Features Centralized data gathering and storage for troubleshooting and engineering analysis n Remote access and control capability from multiple SCADA systems and espWatcher* surveillance and control system in parallel n Plain-language, multilingual alarms and prompts n Event memory for up to 500 events with removable memory module for data logging and trending n PC-based StarView* wellsite display software for device configuration, operation, and troubleshooting n Acquisition system for Phoenix* XT and Select* downhole monitoring gauges, and cable-tosurface (CTS) gauges with Phoenix interface card (PIC) n The UniConn controller replaces the multiple surface components commonly needed for data acquisition, monitoring, and control for variable speed drives (VSDs), fixed speed drives (FSDs), and downhole gauges. The UniConn* universal site controller can monitor multiple well and operating data points—electrical system data, information from external analog or digital devices, data measured by the downhole monitoring system, and remote commands. Users can program alarm and trip settings locally or remotely. In its basic configuration, the UniConn device is a fixed-speed motor controller and data acquisition device. It can be easily adapted for use as a data acquisition and communication hub or VSD controller by adding as many as four expansion cards. Each expansion card is plug-and-play with card control menus automatically added to the UniConn front panel screen. Firmware upgrades are typically performed at the wellsite using a laptop computer connected to the serial port on the front of the controller. Typically, the upgrades are completed in less than 1 minute. The UniConn device can accommodate four analog and six digital input channels and provide two analog and four digital output channels, each individually configurable. For remote monitoring and control, the UniConn system can be connected to a SCADA system and/or the espWatcher surveillance and control system—in parallel, if required. 800 data points).

MVD card The medium voltage drive (MVD) card is the electronic interface between a medium voltage VSD and the UniConn controller. The Modbus TCP/IP card interfaces with client SCADA on all UniConn platforms for protection. or shut down the system to prevent restart until the alarm or fault situations have been rectified. It provides single-portal functionality for all system integration and automation requirements. and vibration data and associated protection parameters. The software also offers live data trending (up to 28. Modbus protocol is encapsulated within the TCP/ IP protocol. Phoenix interface card The PIC is the electronic interface between the Phoenix downhole monitoring systems and the UniConn controller. Specially modified to complement the UniConn controller. the UniConn controller can monitor multiple well and ESP or surface pump operating data points. Universal user interface The UniConn controller’s local display and interface provides user-friendly access for data display. The MVD card operates the line of SpeedStar MVDs. the unified interface shares the controller local display and keypad. programmable under multiple passwordprotected layers with selectable actions—some with adjustable time curves. four fixed-function and five multifunction keys are provided to facilitate simple control. parameter set-point adjustment.

It uses transmission control protocol (TCP) in accordance with standard RFC 793 and Internet protocol in accordance with standard RFC 791. which are each plug-and-play with appropriate menus automatically added to the UniConn front panel screen. The universal design allows the UniConn controller to use the same hardware module for all FSD and VSD control applications. StarView wellsite PC software offers enhanced onsite data viewing.
