Siemens PAC

Supported Devices: Siemens PAC 2200,

  1. Access the menu

    To change the settings, navigate using the meter's display.

    A Siemens PAC2200 on a DIN rail next to circuit breakers, its display showing the instantaneous phase to phase voltages L12, L23 and L31.
    • Press the bottom button (F4) to open the main menu.
    • Navigate to Settings.
    The PAC2200 main menu with Settings highlighted, below Active energy and Reactive energy.

  2. Configure network and communication

    Use a stable network connection. A static IP address is recommended.

    In the Settings menu, go to Communication.

    The PAC2200 Settings menu with Communication highlighted, between Integrated I/O and Display.
    • Select Modbus TCP.
    The PAC2200 Communication menu with its single entry, Modbus TCP, highlighted.
    • Choose Network Settings.
    • IP Configuration:
      • Disable DHCP: Turn off DHCP to prevent the IP address from changing after a reboot (which would break the connection).
      • IP Address: Enter a unique, free IP address.
      • Subnet: Enter the correct subnet mask.
      • Gateway: Enter the correct gateway.
    The PAC2200 Modbus TCP screen with DHCP ticked, the IP address, subnet mask and gateway filled in, and Modbus port 502.

  3. Set current transformers

    Configure the correct CT ratio. This is essential for accurate measurements and correct control.

    • Return to the Settings menu.
    • Select Basic Parameters.
    The PAC2200 Settings menu with Basic parameters highlighted, below Device info and Language.
    • Choose Current Inputs.
    The PAC2200 Basic parameters menu showing Voltage inputs and Current inputs, with Current inputs highlighted.

    • Configure Values:

      • Set the CT Primary and CT Secondary values.
      • These values must match the specifications found on the physical current transformers (e.g., 250A primary / 5A secondary).

      Warning: Incorrect values will lead to wrong measurements, causing the energy management system to malfunction.

      The PAC2200 Current inputs screen with CT primary 250 A, CT secondary 5 A and a display range of 100 A.

  4. Complete the setup

    Once the network data is saved and the CT ratios have been verified, the Siemens PAC 2200 is ready to be integrated into the EMS system.
