hi all!
I just registered here, but I am a long time student-lurker here.
I have gone through and benefited from the tutorial here, and looked through some of the postings.
I have a deadline on my project 2 days from today. My work required me to control an experimental setup using a Modicon MICro TSX3221..
I have successfully made the ladder, and implemented the control using the PL7 software that comes with the device.
I am stuck with the part where I have to send the value of a variable ( %MW1) to a Linux PC. I found some free source code, but things dont seem to be working.
Can anyone help me write just one little number from the memory of the PLC to the serial port of the PC , preferable without having to implement protocols like ModBus? I can manage the Serial port code from the PC side..all I need is help with the ladder on the PLC side.
I am not looking for frills or even reliability, just one simple proof of concept, that I can pick up one variable from the plC, and show it on my Linux PC.
TIA
Gaurav
