Profibus acyclic communication with profibus slave in DP-V1
I would like to ask for support regarding acyclic communication in profibus DP-V1 format. DP-V1 is used for cyclic and acyclic communication (diagnostics information etc.).
I have a Diagnostic repeater from Siemens (type 6AG1972-0AB01-4XA0, http://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang
=en&objid=6AG1972-0AB01-4XA0&caller=view). This repeater is used for partition of Profibus net and for diagnostics information evaluation from profibus net. If you set the segmentation of profibus net, you are able to localize, diagnose and send to control system the information about possible failures with their precise location.
In Siemens PLC family it is possible to read these diagnostic information and logs from the diagnostic repeater using system functions (SFC) of the given CPU.
We need to communicate with this repeater with ABB PLC AC800M to be able to read diagnostics information from Profibus net.
Reading of the diagnostics logs/information is the standard function in DP-V1 format which is not dependent to manufacturer. (information from Siemens help: Reading these data records is a standard mechanism which is supported by all DP V1 mastaters (DS-RD/DS-WR) and is not restricted to an S7-CPU - "Info4.png").
I imported GSD file for the diagnostic repeater in 800xA system. This allow us to add this repeater to hardware configuration to PLC project. This import concation also settings of diagnostic information etc. (see attached images "Import1.png" and "Import8.png").
I would like to ask if anybody have experiences with reading diagnostic information from slaves v DP-V1. If you use this kind of communication. If there are any functions in some library which allow reading these information from any slave.
Reading of the basic diagnostic is available after adding Diagnostic repeater to the hardware configuration. But this diagnostic is only in cyclic communication (1 double word - see attached images "HW1.png" and "HW2.png").
I have searched the information in help, but with no results. I have tried to search on the internet a have found on this phorum some information about DTM (Device Type Manager) - this is one possible way how to read it. But I am not familiar with this solution.
Thank for any comment and recommendation !

You already found this answer -> http://www402.abbext.com/How-read-acyclic-data-ci854-abb-m102p-Relays-q596131.a
spx#commentsList596267 so you know the Controller cannot read Acyclic Profibus data. There is no equivalent function to any of the Siemens system functions in AC800M
"DTMs" are Device Type Manager aspects used by the "Device Management" software feature. This is a separate licensed product but is included on the standard 800xA Install Disks. You will find more information in the Device Management manuals.
