I want to Transfer some data from one card to another card. anyone know how to do it? As I want to send some data from another LFE or card so what is the process? And after completion compile and download is required or not? 

Sir we are using CPU551 and I want to transfer data from one card to another via virtual network. so I want to know what is the process to do that?

Hello.

If you talk about data transfer from one CPU551 to another, then you need to have at least one communication module (CP50M0, CP50M1, CP51M1) which have buffer memory. Configure @GLOB FB to initialize buffer memory. On the CPU which is sender configure CTV FB, at its connector AT you should configure only name of connection (e.g. 'name') without address stage 1 and 2. Also cofigure required virtual connections, whch you want to send to another CPU. On the CPU which is reciever configure CRV FB with the same name at its connetor AR ('name'). Configure also the same virtual connections as you send from first CPU.

But it is easier to use pointer-based communications via CRV_P/CTV_P.

Also look at the manual, chapter 3.2.3 and 3.11.4.

Sir for reference, one attachment is attached. Please check, I want to do same type of connection in my TDC as I had used all free signals. Please describe in detail.
