FX0N RS instructions

[JorgeTorres]

Hello,

 

I'm trying to learn more about FX PLC.

I have an FX0N and I'm trying to use the programming port to send and receive data to/from a computer/microcontroller, but I'm not understanding how it works.

 

I found an example in the manual (page 129):

https://docs.rs-online.com/2432/0900766b8097d44f.pdf

 

I used the same example to receive data from the computer and send this data back to the computer.

However, no matter what hexadecimal data I send from the terminal (PC), it always receives 0x95.

I have attached some screenshots.

 

Can anyone help me understand why this is happening?

Or how can I properly use the programming port?

 

Thank you,

Jorge
