Communication SFB8, SFB9

Hello guys,

In the attached file i made test the communication SFB8, SFB9. It worked ok.

Following the helps file, the R_ID parameter must be identical at both SFBs, so i try to change R_ID in each SFB difference and checked it still work.

So could somebody explain about it?

Hello dany brown,

it could be a programming error or a time stamp error in your program. I recommend to perform the block-consistency check and compile in this dialog the program complete. See in this case the FAQ:

How do you perform a block-consistency check following changes in the STEP 7 program?
