1. A system for connecting casing sections to a casing string, comprising: a top drive system comprising a radially movable gripping member for gripping a casing section;a processing unit for receiving a signal from the top drive system indicative of operational data of a casing connection between the casing section and the casing string, wherein the processing unit is operable to control actuation of the top drive system; anda user interface for conveying the operational data of the casing connection to an operator. 2. The system of claim 1, wherein the radially movable gripping member comprises a slip for engaging an inner surface or an outer surface of the casing section. 3. The system of claim 1, wherein the processing unit is programmable and comprises data storage and memory, and wherein the user interface comprises a display unit. 4. The system of claim 1, wherein the processing unit is operable to compare the operational data to at least one pre-programmed value. 5. The system of claim 1, wherein the operational data comprises at least one of a torque value, a rotation value, a stroke value, an axial load value, and a pressure value. 6. The system of claim 1, wherein the operational data comprises a torque value applied by the top drive system to the casing connection, and wherein the top drive system further comprises a torque sub for measuring the torque value. 7. The system of claim 1, wherein the operational data comprises a rotation value applied by the top drive system to the casing connection, and wherein the top drive system further comprises a rotation counter for measuring the rotation value. 8. The system of claim 1, wherein the operational data comprises a stroke value of the top drive system during make-up of the casing connection, and wherein the top drive system further comprises a compensator to axially stroke the radially movable gripping member. 9. The system of claim 1, wherein the operational data comprises an axial load value supported by the top drive system during make-up of the casing connection, and wherein the top drive system further comprises a sensor for measuring the axial load value. 10. The system of claim 1, wherein the operational data comprises a pressure value of the top drive system during make-up of the casing connection, and wherein the top drive system further comprises a sensor for measuring the pressure value. 11. A system for connecting casing sections, comprising: a top drive system comprising a radially movable gripping member for gripping a casing section;a processing unit for receiving a signal from the top drive system indicative of operational data of the top drive system, wherein the processing unit is operable to control actuation of the top drive system; anda user interface for conveying the operational data to an operator. 12. The system of claim 11, wherein the radially movable gripping member comprises a slip for engaging an inner surface or an outer surface of the casing section. 13. The system of claim 11, wherein the processing unit is programmable and comprises data storage and memory, and wherein the user interface comprises a display unit. 14. The system of claim 11, wherein the processing unit is operable to compare the operational data to at least one pre-programmed value. 15. The system of claim 11, wherein the operational data comprises at least one of a torque value, a rotation value, a stroke value, an axial load value, and a pressure value. 16. The system of claim 11, wherein the top drive system further comprises a torque sub for measuring the operational data. 17. The system of claim 11, wherein the top drive system further comprises a rotation counter for measuring the operational data. 18. The system of claim 11, wherein the operational data comprises a stroke value of the top drive system, and wherein the top drive system further comprises a compensator to axially stroke the top drive system, and a sensor to measure the stroke value. 19. The system of claim 11, wherein the operational data comprises an axial load value supported by the top drive system, and wherein the top drive system further comprises a sensor for measuring the axial load value. 20. The system of claim 11, wherein the operational data comprises a pressure value of the top drive system, and wherein the top drive system further comprises a sensor for measuring the pressure value. 21. The system of claim 11, wherein the top drive system further comprises one or more sensors coupled to the top drive system for measuring the operational data. 22. The system of claim 11, wherein the operational data comprises a position of the gripping member.
