Configuring Digital Inputs/ Outputs on SIG350 with EtherCAT
 
Introduction to SIG350 and EtherCAT
The SIG350, when integrated with EtherCAT, offers robust control over digital I/O operations. This guide will walk you through setting up and managing the digital outputs specifically on Pins 2 (IQ) and 4 (CQ) of the SIG350 ports.

 

Configuration Steps
1. Initial Setup with ESI:
  • Ensure your system has the EtherCAT Slave Information (ESI) for the SIG350 properly installed. This file is crucial for recognizing and configuring the device in your EtherCAT network.

 

2. Configuring Pin 4 (CQ):
  • Navigate to the SLOTS tab where you can configure Pin 4, referred to as CQ.
    • Slots Configuration: Here, you'll see how the ports are mapped, as shown in Figure 1. Adjust settings according to your project requirements.

3. Configuring Pin 2 (IQ):
  • Use the Start-up Parameter tab for settings on Pin 2:
    • Port S1 Pin IQ - Digital Mode: Choose between digital input modes (0 for Normally Open, 1 for Normally Closed), digital output (2), or static on (3) for compatibility with Type B IO-Link sensors.
    • DI Filter Time: Set this to reduce noise if your application requires stable readings.

4. Reading and Writing Data:
  • Reading Input States: For digital inputs, refer to the TxPDO Mapping where:
    • Byte 0, Bit 1 represents the state of Pin 2 on Port 1, and
    • Byte 0, Bit 0 represents Pin 4 on the same port (see Figure 4 and 5).
  • Writing Output States:
    • For digital outputs:
      • Pin 4 outputs are controlled through "Module 1 (Digital_OUT)" with associated RxPDO (Figure 6).
      • Pin 2 outputs are managed via a separate "Module" with RxPDO for each port (Figure 7). Note, the data structure remains 16-bit, but only 8 bits are relevant for Pin 2 outputs when configured as outputs.

Practical Application Tips
  • Consistency in Data Structure: Even when switching between input and output configurations, the data mapping remains consistent, which simplifies your programming logic but requires attention to which bits are active.
  • Sensor Compatibility: If using IO-Link sensors, particularly Type B, ensure Pin 2 is set to "static-on" to maintain sensor functionality.
  • Testing and Validation: After configuration, test your setup by toggling the outputs and monitoring the inputs to ensure they reflect the expected behavior.

 

Troubleshooting Common Issues
  • Incorrect Data Mapping: Double-check your PDO mappings if you're not getting the expected output or input readings.
  • Configuration Mismatch: Ensure settings in the SLOTS and Start-up Parameter tabs match your physical setup and intended use.

 

Conclusion
Configuring the SIG350 for digital I/O over EtherCAT involves understanding the device's specific settings and data structures. By following these steps, you can effectively manage and operate your digital outputs, ensuring they meet the demands of your application. Remember, thorough testing after setup is key to reliability in industrial applications.

 

Happy configuring, and may your control systems run smoothly!
