The Siemens 3VA6 circuit breaker integrates advanced protection, comprehensive power monitoring, and seamless communication into a single, compact, globally compliant device.

There are multiple videos in this lesson so read completely.

The Siemens 3VA6 circuit breaker offers significant advantages for industrial applications:

  • Integrated Power Monitoring: It directly measures current, voltage, power, and energy, removing the need for extra devices and simplifying panel design.

  • Advanced Communication: It easily connects to industrial networks and PLCs, providing real-time data for smart factories.

  • Precise Protection: Offers reliable circuit protection with high breaking capacities and accurate electronic trip units for various fault types.

  • Energy Management: Provides detailed consumption data to identify savings and help with energy management.

  • Simplified Engineering: Tools and features make planning, setup, and maintenance easier.

Siemens Powerconfig Software

This video primarily demonstrates the Siemens Powerconfig software, highlighting its role in configuring and monitoring the 3VA6 circuit breaker.

  • User-Friendly Interface: Powerconfig is presented as a straightforward tool for setting up the 3VA6 breaker.

  • Ethernet Connectivity: It enables seamless communication with the device over Ethernet.

  • Comprehensive Device Access: Users can easily view detailed information about the connected 3VA6 circuit breaker.

  • Parameter Management: The software allows for viewing and adjusting various operational parameters of the breaker.

  • Real-time Measurement: Powerconfig provides the capability to read and monitor live measurement data, including current and voltage values, directly from the 3VA6.

Siemens in Studio 5000

Here's how to integrate a Siemens device into Rockwell Studio 5000, using Modbus TCP:

  1. Get the Modbus TCP AOI: Download the appropriate Add-On Instruction (AOI) from Rockwell's sample code library.

  2. Import the AOI: Import the downloaded AOI into your Studio 5000 ladder routine.

  3. Configure the Connection: Set the IP address of the Siemens device (e.g., 192.168.20.10) and the local slot address within the AOI's connection parameters. The destination port is typically 502.

  4. Set Up a Transaction: Define a transaction to read data. Specify the transaction type (Holding Register Read - code 3), the Siemens device's station ID (e.g., 126 for a 3VA6 breaker), the starting address of the data, and the number of registers to read.

  5. Enable and Interpret: Enable the Modbus TCP client and interpret the incoming data. This may involve combining 16-bit registers into 32-bit values and adjusting byte order. The video highlights that you may need to experiment to find the correct register address and byte order.
