Functions
8.7 Identification and maintenance data (I&M data)
Reading and writing the I&M data with STEP 7
In STEP 7 the I&M data are displayed in the tabs "Module state – IM 153-2" and "DP Slave
properties" (see online help for STEP 7).
In the HW Config you can enter the modules M data (e.g. in a dialog box during the
configuration).
The access to the I&M data takes place in accordance with the IEC 61158-6 standard.
In the H system the interface module from which the I&M data is to be read must be available
online.
Reading and writing the I&M data without STEP 7
If you wish to use the I&M data without using STEP 7, you must carry out the data access in
accordance with the specifications of the PROFIBUS Guideline – Order No. 3.502, Version 1.1
May 2003.
In the H system the interface module from which the I&M data is to be read must be
addressed (slot 245 or 246). Slot 245 labels the left interface module, slot 246 the right
interface module on the BM IM/IM.
Example for reading the I&M data
The user can access specific I&M data via Read data record. A two-level access is necessary
for this:
1. Data record 248 has a directory in which the associated data record numbers are given for
the various
indices (refer to the following table).
