Supplementary information
Supplementary information on PROFIBUS DP
Monitor/Modify, programming via PROFIBUS
You can use the PROFIBUS DP interface to program the CPU or execute the programming
device functions Monitor and Modify.
Note
The "Programming" or "Monitor/Modify" applications prolong the DP cycle if executed via the
PROFIBUS DP interface.
Determining the bus topology in a DP master system using SFC 103 "DP_TOPOL"
The diagnostic repeater is available to improve the ability to locate faulty modules or an
interruption on the DP cable when failures occur in ongoing operation. This module is a slave
that recognizes the topology of a DP segment and detects any problems caused by it.
You use SFC 103 "DP_TOPOL" to trigger the identification of the bus topology of a DP
master system by the diagnostic repeater. For information on SFC 103, refer to the related
online help and to Manual
System and Standard Functions
. The diagnostic repeater is
described in Manual
Diagnostic Repeater for PROFIBUS DP
, order number 6ES7972-
0AB00-8BA0.
Adding modules with ET 200M at a later time
If you want to add modules with the ET 200M while using IM 153-2, MLFB 6ES7 153-2BA00-
0XB0 or higher, or an IM 153-2FO, MLFB 6ES7 153-2BB00-0XB0 or higher, note the
following: The ET 200M must be equipped with an active backplane bus with sufficient free
space
for the planned expansion. Include the ET 200M so that it complies with IEC 61158.
Adding modules with ET 200iSP at a later time
If you want to add modules with the ET200iSP, the expansion of the terminal modules
should have sufficient reserves from the start and be fitted with unconfigured reserve
modules.
