MPC (Multi-Pump Control)

Overview

Multi-Pump Control software is designed to control up to 24 Frac Pumps simultanously from one PC. The pumps can be controlled individually or in groups. Software allows to control and monitor all engine, transmission, pump and hydraulic system parameters. All diagnostic messages (alarms, warnings and events) and CAN J1929 DM1 messages are displayed. Additionally Overpressure Setpoint and Overpressure Setpoint Limit ensure save pump operation. 

The software communicates with pump over TCP Modbus Protocol.

Global Total Rate And Total Discharge Box

The global total rate and total box displays calculated total discharge rate and total from all pumps.

C-Pump Control Window

C-Pump Control window allows to control each c-pump individually or globally from Global C-Pump Control Bar.

Single C-Pump control box

Global C-Pump Control Bar – allows to control all C-Pump simultanously

  C-Pump Speed – Set C-Pump speed to 0, 50, 75 or 100%

  C-Pump Speed Up/Down – Increase/Decrease C-Pump speed 

Details Window

To open Details Window click on one of the following buttons:

  Engine

  Transmission

  HP Pump

  Hydraulic system

Red symbols and blinking indicates that one or more errors occured.

Diagnostic Messages

Diagnostic Window display all warnings and alarms from

CAN Diagnostic Messages (DM1)

CAN Diagnostic Messages window display J1929 DM1 messages received from engine, transmission or pump.

For exact SPN, FMI message search in manufacturer component documentation. In some cases messages can be different.

Data Stream

MPC Data Stream feature allows to stream data in ASCII format to third party software in realtime. MPC acts as TCP/IP Server and accepts max 10 connections simultaneously.

Data Stream Channels

For data streaming MPC generates following channels:

  1. Timestamp
  2. Maximum Discharge Pressure all pumps
  3. Average Discharge Pressure all pumps
  4. Combined Pump Rate all pumps
  5. Combined Pump Total all pumps
  6. Maximum Discharge Pressure pumps from group A
  7. Average Discharge Pressure pumps from group A
  8. Combined Pump Rate pumps from group A
  9. Combined Pump Total pumps from group A
  10. Maximum Discharge Pressure pumps from group B
  11. Average Discharge Pressure pumps from group B
  12. Combined Pump Rate pumps from group B
  13. Combined Pump Total pumps from group B
  14. Maximum Discharge Pressure pumps from group C
  15. Average Discharge Pressure pumps from group C
  16. Combined Pump Rate pumps from group C
  17. Combined Pump Total pumps from group C
  18. Maximum Discharge Pressure pumps from group D
  19. Average Discharge Pressure pumps from group D
  20. Combined Pump Rate pumps from group D
  21. Combined Pump Total pumps from group D

For all generated channels MPC uses units from first connected pump. Mixing unit systems will cause calculating incorrect values.

Data Stream Settings

Data format can be set to meet third party software needs.

There are following options available:

  • enable/disable data streaming
  • set server port
  • Timestamp format
  • Separator between values
  • Decimal separator
  • Data Rounding
By applying settings currently generated record in selected format can be seen in preview window.

Data Logger

MPC Data Logger allows to log data in CSV file. To start logging data to file click on Data Logger on top right side on main screen.

Logging data is indicated by blinking red circle

By selected option ‘Autostart’ data logging starts automatically with program start.

In job name window user can assign a name of existing data file or start new file.

All data files are stored in default MPC folder. To navigate to that folder use ‘Open folder’ button.

Data filenames are combined from timestamp and job name:

When job name is empty filename contains only timestamp. The filename can be renamed every time even during logging to file.

Logging is possible only when minimum one pump is connected.

CSV Data File

Each CSV data file contains header with channel names and channel units. Channel units are taken from first connected pump.

In case of incorrect display in Excel program, data format must be set to meet local country settings. To change data format refer to Data Logger Setting below.

Data Logger Channels

Data logger generates following channels:

  1. Timestamp
  2. Maximum Discharge Pressure all pumps
  3. Average Discharge Pressure all pumps
  4. Combined Pump Rate all pumps
  5. Combined Pump Total all pumps
  6. Maximum Discharge Pressure pumps from group A
  7. Average Discharge Pressure pumps from group A
  8. Combined Pump Rate pumps from group A
  9. Combined Pump Total pumps from group A
  10. Maximum Discharge Pressure pumps from group B
  11. Average Discharge Pressure pumps from group B
  12. Combined Pump Rate pumps from group B
  13. Combined Pump Total pumps from group B
  14. Maximum Discharge Pressure pumps from group C
  15. Average Discharge Pressure pumps from group C
  16. Combined Pump Rate pumps from group C
  17. Combined Pump Total pumps from group C
  18. Maximum Discharge Pressure pumps from group D
  19. Average Discharge Pressure pumps from group D
  20. Combined Pump Rate pumps from group D
  21. Combined Pump Total pumps from group D

For all generated channels MPC uses units from first connected pump. Mixing unit systems will cause calculating incorrect values.

Data Logger Settings

In Data Logger Settings window following option are available:

  • Maximum period for keeping file on disc (1, 3, 6, or 12 months). All older files will be automatically deleted.

Data format options:

  • Timestamp format
  • Separator between values
  • Decimal separator
  • Data Rounding

MPSim (Multi-Pump Simulator)

MPSim is a Multi Pump Simulator software that allows user test almost all MPC features. MPSim is a part of MPC installation and will be installed together with MPC.

To start MPSim click on icon

MPSim simulates 24 pumps. In order of connect MPC with MPSim user has to setup IP and Port in MPC Configuration (Settings) window.

MPSim acts as 24 TCP modbus servers on local IP: 127.0.0.1 and ports accordingly 50201-50224.
