PROFINET Fieldbus protocol

PROFINET enables deterministic, real-time communication between vacuum pumps and PLCs, while eliminating the constraints of traditional point-to-point wiring (SIO).

 

What PROFINET Brings to Vacuum Applications

Drastic Reduction in Wiring Costs

Unlike an SIO system where each vacuum pump requires its own cable connected directly to the PLC, a fieldbus network allows dozens or even hundreds of devices to be connected on a single communication line. Depending on the configuration, wiring costs can be reduced by a factor of 5 to 10.

Savings apply to:

• cabling material,
• installation labor,
• and electrical cabinet space.

This delivers an immediate and measurable economic benefit for the customer.

Direct PLC Integration

Vacuum parameters and operating statuses are exchanged directly with the PLC via PROFINET, without additional interfaces or signal converters.

Centralized Commissioning and Diagnostics

Each vacuum pump is identified on the network, monitored in real time, and faults can be precisely localized:

• line interruption,
• defective equipment,
• incorrect parameter settings.

Advanced Data Exchange

Beyond a simple ON/OFF signal, PROFINET enables access to:

• vacuum pump health status,
• alarms and anomalies,
• cycle counters,
• configuration parameters.

This is a key enabler for predictive maintenance and Industry 4.0 strategies, now central to modern machine development.

Flexibility and Scalability

Adding a new vacuum pump to an existing PROFINET network only requires a local connection and software configuration, without running new cables back to the control cabinet.

This provides a major economic advantage throughout the entire lifecycle of installations subject to:

• line extensions,
• process modifications,
• production upgrades.

Decentralized Installation

Vacuum pumps can be installed closer to the gripping points, reducing:

• vacuum build-up time,
• compressed air consumption,
• cycle time variability.

Reduced Cabinet Footprint

Limiting cables, terminal blocks, and I/O modules significantly reduces the space required within PLC environments and electrical cabinets.

Accuracy and Immunity to Disturbances

Digital communication prevents signal degradation typically encountered over long analog transmission distances:

• voltage drops,
  
• EMC disturbances,
  
• signal losses.

The vacuum values received by the PLC are exactly those measured by the vacuum pump, without degradation.

Typical Applications

• Automated assembly lines
• Robotic palletizing and pick-and-place systems
• Packaging and handling equipment
• High-speed industrial processes
