9.2
Access to the I/O system 1000
In the following, the access under PROFINET to the following ranges of the I/O system 1000 are
displayed:
• I/O area
• Parameter data
• Diagnostic data
GSDML file
For configuring a Device-I/O interface connection in your own project planning tool, you get the
performance features of the PROFINET components in the form of a GSDML file.
This file is either located on the enclosed data medium or in the download area of www.lenze.de.
Install this GSDML file in your project planning tool.
More information on how to install the GSDML file can be found in the manual for your project
planning tool. Structure and contents of the GSDML file are defined by the IEC 61158 standard.
Handling blocks
For accepting or changing data records during runtime, two corresponding handling blocks for
reading/writing data records are required. For CPUs to be programmed with STEP7 by Siemens, the
following handling blocks are available:
• SFB 52 Read data record
• SFB 53 Write data record
• SFB 54 Read diagnostic data
With "slot" you address the module and via "index" you address the data area related to a module.
Note!
Please note that the supply and terminal modules do not have any type identification.
They cannot be identified by the PROFINET coupler and are thus not considered in the
listing or assignment of the slots.
In the following, slots within PROFINET are called PROFINET slots. Counting always starts
at 0.
