Operation Principle
- Logging Computers

530 Logging Main Computer and 530 Auxiliary Logging Computer form a dual-computer system for 530-series, 520-series, 521-series and cased hole production loggings, perforating and coring, and other domestic logging. It adopts Windows-2000 operation system as an open platform. The 530 Logging Main Computer is the CPU of the system, and it completes the software initialization of the main control module and DSP modules etc. after starting the system; it completes the orderings of display, plotting recording and management of various data, as well as of the disposition of tool strings, power on the down tools, calibration of down tools and operation of pad-mounted device during logging. The 530 Auxiliary Logging Computer can exchange data with 530 Main Logging Computer through a Net Exchanger and process the data while logging. It can promote logging efficiency. If the 530 Main Logging Computer fails, the 530 Auxiliary Logging Computer can quickly be connected into the system through the ether net port to complete the logging operation. With the switchover, the plotter can be separately connected with 530 main and auxiliary logging computers for log plotting after logging.

DITS (EXCELL-2000) Main Logging Computer is a special logging computer of DITS–series tools, it is connected with the main control computer PC104 through ether net to complete the display, plotting, recording and management of relative logs, and to control down tools.
