KC868-A8, Settimino, connection to Siemens PLC

[vooszoo]

Hello,
I'm trying to connect this board to Siemens PLC directly, using S7 Protocol with no luck. Have anyone tryed this?
There is another option using TCP Server-client connection, will try this later.
I'm looking for direct connection to PLC without MQTT broker and others.

if you want PLC connect with KC868-A8 directly, no problem, just you should write a arduino code download to ESP32 firstly, you can create a simple protocol for your Siemens PLC.

Using existing protocol (S7 protocol) do not require any code on PLC side. That's why it is best option. Writing own protocol, or using modbud or any other needs code on PLC side. Settimino is implementation of S7 protocol on ESP32 and it's working with W5500 ETH module, but I can't get it to work with LAN8720 module used in A8 board

so if you want KC868-A6 board work with S7 protocol, you need to write arduino code for ESP32.
i think you can see this video tour: https://www.youtube.com/watch?v=c2T2lAMDWGs about S7 work with arduino code.
