Is it possible to share tags though Profibus on S7-300?

Post by asteroidehk »

Hello friends

I have a CPU-314C-2 DP and a CPU-315-2 DP

I would like to know if is it posible to share tags (integer, floats, flags,etc) between them thoough Profibus.

If it is posible, How can I do that?

I have a simple program communicating though Profibus in a master slave mode, but this i sharing just bits, I would like to share intergers, floats, counters, timers.



Thanks a lot :D
