B1. Before Using the DTSXL System

B1.1. Functional Overview of the DTSX3000

The DTSX3000 of the DTSXL System measures the temperature distribution over the
length of an optical fiber using the fiber itself as the sensing element. The module can
be combined with appropriate power supply and optical switch modules to configure a
required system. It can be accessed using the optional DTSX3000 Control Visualization
Software (DTAP3000), using the DTSX3000 Data Conversion Software WITSML1.3.1.1
(DTAP3000D), or via the communications interface of a host computer.
- Temperature distribution measurement range of up to 16 km is supported using
optical fibers as temperature sensing elements. Temperature distribution
measurement of up to 50 km is available as an option.
- Multiple channel measurement with auto channel switching allows up to 16 sensing
fibers when an optional optical switch module is used.
- Channel sequencing, sequence start time and sequence intervals are
programmable as measurement sequences.
- Modbus communication support allows the DTSX3000 to be controlled from
STARDOM or CENTUM.
- File transfer protocols (SFTP, SCP) are supported so measurement data can be
retrieved from a host controller or data server.
The HTTP client function enables data transfer to a HTTP server using PUT or
POST.
- The DTSX3000 can be accessed from a Web browser running on a host PC for
performing network-related configuration, backup, restore, system revision update
and other maintenance operations.
- Up to 50 alarm sections, each configured with its own alarm conditions for alarm
reporting, can be defined by distance for temperature measurement data.
- Up to 200 sections can be defined by distance for temperature measurement point
data. Point data (average value, maximum value, etc.) can be calculated from
temperature distribution data and output for each section.
- Measurement data can be saved in LAS (Log ASCII Standard) format or CSV
(comma-separated values) format. Using the optional DTSX3000 Data Conversion
Software WITSML 1.3.1.1 (DTAP3000D), measurement data can additionally be
saved in WITSML (Wellsite information transfer standard markup language) data
format.
- Power save mode ensures low power consumption.
- RAS functions (self-diagnosis, optical fiber failure detection, etc.) are provided.
