@Jaime:
First of all: please, do not necro bump! The last message in this thread is nine years old!
It's always better to open a new thread...
Second, your question:
I don't know if
http://www.meliksah.edu.tr/muzam/UZAM_PLC_with_PIC16F648A.htm project is still alive. I really doubt it.
But you can see my Open Hardware + Free Software PLC at
https://osimplc.com .
It uses LDmicro as programming software, and various different softwares for machine-code serial transfer.
OSIMPLC is an educative project, but it can be also used to perform simple tasks in productive environments.
OSIMPLC has a PIC16F887 on board; and a new and more powerful replacement module, ATmega1284P based, is in beta stage.
Feel free to write to me via info at osimplc dot com. I speak spanish, so if you too, you can talk to me using a videoconference software like Jitsi Meet...
Best regards,
