NXP Application Code Hub

Remote IO Platform: ECAT Sample Application

This application showcases the analog and digital I/O features supported by the Remote IO Platform in combination with the EtherCAT industrial protocol. The platform communicates over ethernet with a TwinCAT-driven soft-PLC application running on a PC.

The features include:

• Signal generator
• MCU Digital Input pin control
• MCU Digital Output pin control
• AFE Digital I/Os control
• External Voltage Signal Measurement (HVSIG)
• Current Measurement
• Temperature Measurement
• Internal Voltage References measurement (LVSIG)
• Voltage Calibration
• Resistance Calibration
