Industrial Networks & Integration
This lesson covers how to configure IO Link integration via Ethernet/IP and Modbus TCP, depending on your controller hardware.
Controller-Specific Configuration
If your Micro850 has "L50E" or your Micro870 has "L70E" in the part number:
Use the direct IO Link integration method. This is designed for controllers with built-in Ethernet/IP support, allowing for more seamless integration with your IO Link masters and devices.
If your PLC does not include the L50E or L70E in the part number:
You must use the Modbus TCP method. Since these controllers do not natively support the same level of Ethernet/IP integration for IO Link, you will communicate with your IO Link master using Modbus TCP.
Communicating via Modbus TCP
When using the Modbus TCP method for IO Link, note that Modbus data addresses can be tricky. Pay close attention to the specific addressing table for your IO Link master and how the data is mapped to your Modbus registers. Ensure you verify the byte order and address offsets to match your PLC's data requirements.
