I would like to know if anybody has experiences with detailed diagnostics of individual inputs/outputs (digital and analog) on inserted modules on the rack. I found information that SSL-ID W#16#0091 reads modules and submodules information (but only for S7-400). But how can I get to each individual input or output diagnostic ? Is it possible ? W#16#0091 Module status information of all inserted and configured modules/submodules of the CPU (S7-400 only) Is it possible to get these information also from S7 300 CPU ? Unfortunatelly i did not have much time to try it, so if anybody has some experience... Thanks in advance.

Normally we use for basic diagnostics within SFC51 (W#16#292) for Profibus DP diagnostics. For slave diagnostic on Profibus DP we use SFC13. I have no experiences with SFC59, so I will test it. For now, I am not sure what are the differencies between SFC51 and SFC59 but I will go through it to know.. Thanks.

I want to read the diagnostic data from all IO modules on tha rack continously in OB1. I found some example of reading diagnostic data only in case of faulty module (reading in OB82). I have attached three pictures: 1)Hwconfig.png - my HW configuration. There are I modules, Q modules, Power modules... 2)DiagRead.png - example of implemented program. Fot the test I want to read 10 data records from the first modules. 3)DiagReadModule.png - example of parameters for analogue input module. There is an information for "Group dagnostic" SZL_ID:W#16#B1 Index: I thought that it is position of the module on the rack. But in thread /tf/WW/en/Posts/26517 I found out that it is diagnostic address. But I am not confused now, I could not see any diagnostic address for IO modules, I can see only for power modules. Thank you for any help. Thanks in advance. Attachment _Diagnostics.zip (1285 Downloads)

As mentioned in help, this settings is better for my application. Addressing of the modules is: "You specify the number using the rack and slot number." as INDEX. I call SFC51 directly in OB1 to read statuses all the time. I use loop to read only status from one module at one time.. I tried to search for information I get from modules (diagnostic data record 1) but I was not successful. If anybody knows, where can I find these information please let me know. Thanks in advance.

Thank you for you post, I studied these information from help on SFC51... I tried bothSZL_ID:W#16#B1 andSZL_ID:W#16#B2. I have to study it carefully once again. To this time, the corresponding bits have not suited to my hardware and actual status of this hardware Aretadvised me to use SFC59, but to this time I had no opportunity to test it I still cannot finad more deep information. For example in the .pdf file: in 1st Byte, Bit0 to Bit 3: Module class (CPU, FM, CP, IM, SM).... this is general information, but where can I find out which combination of bits means CPU, SM etc.I tried to find out from catalog information from SM, but without success I will study harder Regards.
