Diagnostic address issue

Hi all,

Last week i commissioned 2 RIO panel with CPU-417-5H and CP-443-5. In previously, the cpu and CP card communicating with different RIO's (70 Nodes with redundant IM's). Now we added 12 Nodes.

the communication wise it is working fine. previously i have reading the module status from IM153-2 by SFC-13, which was called for all RIO's and kept as a continuous cycle monitoring.

after added 12 nodes, i able to read 6 nodes only, remaing 6 nodes i couldnot able to read from SFC13, which is showing 80c3 error. in that block i kept old address, that time i can able to read. but its cannot read the new diagnostics address.

Please advise us.

Thanks,

Hi,

80C3 error code mean: "The required resources (memory, etc.) are currently occupied."

See the SIMATIC System Software for S7-300/400 System and Standard Functions - Volume 1/2 under chapter "16.4 Reading Diagnostic Data of a DP Slave with SFC 13 "DPNRM_DG"
(Slave Diagnostics)". You will be directed to page 160.

You need to deal with the overhead in your system. Try to rationalize the block calls. This will solve your problem!

  i did the program based on the timer. once i have finished the testing i will update the status.

HI,

i DID THE PROGRAM BASED ON THE CYCLIC INTERFACE. THAT TIME ALSO I CANNOT FETCH THE DIAGNOSTICS DETAILS. EVEN I DISABLED ALL SFC AND I CALLED ONE SFC WITH THAT ADDRESS STILL PROBLEM EXISTS 

THANKS,

Hi,

Rationalize your block calls. Do not call all the SFC13's in the same cycle, this might solve your issue.

Alternatively you could watch the BUSY output goes 0 before the next execution.

This FAQ might help you to understand the problem.:

Can you use the "Signal System Error" function, the FB126 function block and the SFC13 "DPNRM_DG" system function simultaneously?

Hi Micro,

Thanks for your answer. I fetched the data by using  SFC 51.  Instead of SFC 13 i used SFC51 with SSL ID- W#16#B4. This SSL ID working like SFC-13. 

Thanks,
