I'm looking for a very low latency communication option between raspberry pi running codesys and arduino, I know that spi is fast but i dont know how to setup spi com in codesys, anyone with experience doing so I would love some advice, my setup contains 2x teensy 3.6 slaves and 1 raspberry pi master.
I'm currently using modbus TCP to do my comunication but so far my average latency for a round trip around 10 -20 ms and as my project size increases I expect this latency also to increase, so any suggestions to get lower latency ?
