8.7.1 I&M data for PROFIBUS DP
As of IM 153-2Bx00 this data is available on the ET 200M.
Note
Only one DP master can access the I&M data of an ET 200M at any one point.
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.
