Siemens PAC

Supported Devices: Siemens PAC 2200,

1. Accessing the Menu

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

• Press the bottom button (F4) to open the main menu.

• Navigate to Settings.

2. Network & Communication (Modbus TCP)

A stable network connection is crucial. It is highly recommended to use a static IP address.

In the Settings menu, go to Communication.

• Select Modbus TCP.

• 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.

3. Setting Current Transformers (CT)

Configuring the correct CT ratio (Transformation ratio) is essential for accurate measurements and correct control.

• Return to the Settings menu.

• Select Basic Parameters.

• Choose Current Inputs.

• 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.

  

4. Completion

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.
