Hi,
I am doing a project on sensors. I am also using a serial communication (RS232) for my application but i have realized that i can't run 2 applications at the same time. I have got a problem in communications between the ladder diagram and the PLC. How do i design my Ladder Diagram in such a way that when a sensor is detected the signal is sent from the I/O port input to the serial cable back to the Ladder Diagram (showing sensor has detected something).Thanx
