Product Overview

The Weatherford 8500 driver enables the monitoring of real-time data and immediate control of Rod Pump Controller (RPC) devices and other Weatherford controllers used at wellhead facilities. It provides an easy and reliable way to read and write data to Weatherford series devices via the Weatherford 8500 protocol through client applications (including HMI, SCADA, Historian, MES, ERP, and countless custom applications).



  • Supports up to 256 communication channels and up to 4095 devices/controllers
  • Supports data acquisition for Downhole Dynagraph data
  • Supports event directory retrieval
  • Supports surface and downhole card retrieval
  • Supports valve check data item syntax
  • Supports Advanced Statistics Tags, including _CommFailures, _ErrorResponses, and more

Release Notes


EX5 - 5.20.396.0

  • Added the ability to format Date and Time values as ACSII numeric strings.


EX5 - 5.19.467.0

  • Added support for Advanced Statistics Tags, including _CommFailures, _ErrorResponses, and more.
  • Enhanced the driver to allow the RTU P619 value to be queried prior to a Dynagraph request. The result of this request determines the “position inclusion and type character” parameter when building the Dynagraph transaction.


EX5 - 5.10.205

Updated the driver with the new Connection Sharing feature.


EX5 - 5.9.170

Added the new device-level internal tag "_FailedConnection" that indicates the driver failed on its attempt to connect to the device.


EX5 -

Fixed a Communication Serialization bug that prevented the driver from releasing communication control when there were many memory and/or Write Only tags with scan rates.


EX5 -

  • Added channel serialization.
  • Added support for the following models: EPIC, M2000, WellPilot Classic, 8800, 8750, 8650, and 8500.
  • Added Inter-Device Delay


EX5 -

  • New serial driver that allows the 8500 Protocol to communicate with Weatherford model 8500 RPOC controllers. Ethernet Encapsulation is supported.

Featured Suites

A driver is a software component that enables KEPServerEX to meet the communication requirements of a specific device, system, or other data source. The driver handles all proprietary communications between the data source and KEPServerEX; KEPServerEX handles all OPC or proprietary client communications between the driver and the client application(s).

Drivers may be licensed individually or in suites. Additional drivers can be licensed on demand as connectivity needs evolve. All OPC client interfaces can connect to KEPServerEX without additional charge.
