PC 104 replaces PLC

greenspun.com : LUSENET : Elevator Problem Discussion : One Thread

Dear Sirs

I was asked to develop a software to replace the existing PLC ladder diagram in a small-medium elevator system. Now, I don't know how to begin the project. Can anybody help me or can anybody introduce me some references. Anything you do will be appreciated.

Thank you very much
