What is a servo press?

A servo press uses servo motors for precise force and position control during forming operations.

Servo Press Network Integration: PROFINET and EtherNet/IP

admin

## Why Network Integration Matters

Connecting your servo press to the factory network enables:
- Real-time production monitoring (OEE, parts count, cycle time)
- Remote fault diagnosis
- Automatic production reporting
- Integration with MES/ERP systems

## PROFINET Integration (Siemens S120 drives)

The Siemens S120 drive communicates via PROFINET. To integrate with a Siemens PLC:

1. Add drive to TIA Portal hardware configuration
2. Configure telegram type (Telegram 105 for servo press: position + velocity + torque)
3. Map process data to PLC data blocks
4. Configure cyclic data exchange (typical: 4ms cycle time)

Key data to read from drive:
- Actual position (r2521)
- Actual velocity (r2522)
- Actual torque (r0080)
- Drive status word (r0899)
- Active faults (r0945)

## EtherNet/IP Integration (Allen-Bradley systems)

For presses with Yaskawa or Fanuc drives in Allen-Bradley environments:

1. Install EtherNet/IP adapter module on drive
2. Add drive EDS file to Studio 5000
3. Configure I/O connection (implicit messaging for cyclic data)
4. Map drive data to PLC tags

## OPC-UA for MES Integration

For connecting to MES or cloud systems, OPC-UA is the preferred protocol. Most modern servo press controllers support OPC-UA natively. Configure OPC-UA server on press controller, then connect MES client.

## Data to Log for OEE

- Parts count per shift
- Downtime events with fault codes
- Average cycle time
- Tonnage trend (for die wear monitoring)

Good overview on PROFINET integration. One thing worth adding: make sure your PLC cycle time matches the servo drive position update rate. We had a case where the PLC ran at 10ms but the drive needed 4ms updates for accurate BDC detection — caused intermittent position faults that were hard to trace.

For EtherNet/IP users: watch the CIP implicit messaging timeout. Default settings are often too aggressive for press applications where the slide dwells at BDC.

For PROFINET on Siemens S120, the drive already has it built in. For Yaskawa, you need the SI-EP3 EtherNet/IP option card or SI-P3 PROFINET card. About $800 each. The data you can pull: cycle count, motor temperature, torque, position, alarm status. Enough for basic OEE monitoring without any additional sensors.
