The structure of thedata sets is defined in the PROFINET IO specification (see IODReadReq orIODReadRes). The data set number (index) allows to distinguish between thediagnostics level and the diagnostics structures.The following diagnostics data sets can be requested in case of an upcomingdiagnostics message:Data set number Description Available onslot0x800A 327780x800B 327790x800C 32780Standardized channel diagnostics of a sub-moduleslot (sub-slot specific) 0 ... 1280xAFF0 45040 Data sets for identification and servicing purposes 00xC00A 491620xC00B 491630xC00C 49164Channel diagnostics of a slot (slot specific); currentlyidentical with the data set number 800AH, as onlyone sub-module can exist for each module. 0 ... 1280xE002 57346 Deviations in the set and actual configuration of thesub-modules allocated to the I/O controller (I/O-AR). 00xE00A 573540xE00B 573550xE00C 57356Channel diagnostics of all signal channels allocatedto a connection (AR), contains all channeldiagnostics structures of the sub-module slots. 00xF00A 614500xF00B 614510xF00C 61452Channel diagnostics of all signal channels allocatedto the application profile 0 (API 0)*1) , contains allchannel diagnostics structures of the individual sub-module slots. *1)0*1) Several connections (AR´s) can be established to an API. The buscoupler only enablesone connection (AR) of the API 0 to an I/O controller in the firmware versions 01 and 02.3.1.7.2 Structure of the Standardized Diagnosis Data SetsThe diagnosis data sets comprise of several structure elements. The firstelement in the data set is the head of the structure. It describes the version andthe length of the following data. An identifier (BlockType)specifies thestructure of the diagnosis data. The following identifiers are currently used bythe buscoupler:
