Ok. We talk about different things.

Previously I told about data exchange between CPU's inside one rack via buffer memory.

Now you talk that you want transfer data from CPU in 1st rack to the CPU in 2nd rack. This is a little bit different transfer. You need to find in your program CTV FB with 'BXDXX0' at its CRT output. Look at its CTS input, here is the HW address of CP via which the data are transferred. The number of channels and data length depeds on the CP used.

 Tomorrow I will share you some attachment sir.

Do you know about DI & AI module HW configuration with IM153? 

KSN

Yes, I have some experience with ET200 and TDC configuration. 

 Sir I want to know one thing more when we do virtual communication with one CPU to other CPU. Which CPU needs to compile & download. Or both CPU needs to download, please reply. 

KSN

You will need to compile and download both CPU's. 

 Oky sir thanks.
