Integrating several field devices (inductive and capacitive sensors) into a single interface like Ethernet


 I have a request for integrating several signals from sensors into a single interface. It was thought to be made using IO-link, but  due to availability in my country and cost I am asking here for other options. The controller that will receive the signals will be programmed and mounted by another group of engineers, I think it will be an Allen Bradley controller. 

 We'll have ultrasonic sensors for level measuring, and indusctive and capacitive sensors. I see that the siemens IO-link devices only work with profibus and profinet, I would like to know if any of you has done this integration and how it can be done with a final ethernet interface that any other manufacturer like Allen Bradley can communicate with.

Thanks in advance.
