Getting Started in C


Thread Starter

Roland Tollenaar

For an automation project I am looking at Beckhoff I/O modules. For particular reasons I will have to set up the Modbus TCP/IP communication with it myself. I have some (not much) experience in application layer programming but it would be very helpful to look at other code snippets. Does anyone know of open C routines I could look at?

Approximately 3 years ago I developed a system using a Texas Instruments 545 PLC, and Beckhoff remote I/O. I did this using profibus comms. This year the system had to be replaced, I believe because Beckhoff either went out of business, or quit supporting thier I/O. I would suggest you check on availability/support before committing to Beckhoff.
