PC communication with S5?

[Guest Wouter]

Hi I've never worked with Siemens, but I was wondering if it's possible with an S5 PLC to establish a PC-PLC connection with it, in order to retrieve information about I/O's on your computer. And if it's possible, what protocol do I need to "talk" to the PLC? I just want to make a program that allows you to control inputs, outputs, coils,... (in Visual Basic 6.0) Can anybody help me with that? Thank you!

Yuo might look at a book called Home Automation Basics by Thomas E. Leonik I bought mine at overstock.com for cheap. its all about vb6 and micrologix 1000 but the author says it will all work with any plc that communicates serially Dave
