aka Schlumberger Winch Data transfer to RigWatch (SLB to RW)

Operations Rationale

During logging operations, local convention widely distributes Schlumberger winch position (WPS). Tool string depth is a readily consumable gauge of both progress and status of logging operations.

System Overview

Schlumberger provides JRSO with winch position (WPS) telemetry. JRSO implemented SLB to RW software system to bring that data into RigWatch. The core of the SLB to RW system consists of WPS to WITS conversion. The system is presently running on a Dell laptop (SHIP-DAQ). In its present configuration, the software system processes WPS telemetry as indicated.

• COM4 - Input. WPS telemetry (a binary stream) is received via an RS485 serial connection from the Schlumberger rack.
• COM3 - Output. SLB to RW--a LabVIEW program--processes incoming WPS telemetry (COM4) to WITS format. The WITS stream is output via COM3.
• COM1 - RigWatch input. COM3 is physically connected in loopback fashion to COM1. The loopback cable is known as a null-modem or cross-over cable.

A local instance of RigWatch identified as "Remote 6". The RigWatch Master is configured to connects across the network to ingest the WITS data on device "COM1 - Remote 6".
