ecat_digital_io
Overview
This example demonstrates how to develop a remote IO device based on Slave Stack Code(SSC).
This remote IO device only supports SM-Synchron mode for DC operation, and implements one Input channel and one Output channel: Output channel: connected with the LED and used to control this LED. Input channel: used to read the LED current status.
Note that the demo CAN NOT be built directly. Please see the “Prepare the Demo” section for more details.
Running the demo
When the example is running, the serial port will output:
Start the SSC digital_io example...
After the PLC program started, the LED starts to blink with 0.5Hz frequency.
NOTE: refer to the User Guide for the details of how to setup the PLC project on TwinCAT3.
TwinCAT Setup
To demonstrate this servo system, TwinCAT is used as the EtherCAT MainDevice.
