Import-User-1 Posts: 3609 Rating: (29)	Import of a Technical Question of the User acharki acharki Dear all, I have a problem with profibus-dp communication, between CP342 and a lot of siprotec relays. The problem is that the length of the CP 342 is just 256 bytes and I have to communicate more than 500 bytes So please tell how to resolve this problem without changing or adding CP, and if I have to add a program, so please tell me how. Thank you for helping me
