Siemens IM 151-7 - Functions Via the PD;OP

ET 200S in the PROFIBUS Network
4-9
ET 200S IM 151-7 CPU Interface Module
A5E00058783-04
4.4 Functions via the PD/OP
You can use the PD to:
 Configure the IM 151-7 CPU with ET 200S modules and put them into operation
on the PROFIBUS-DP
 Program the IM 151-7 CPU
 Execute test functions such as ”Monitor/Modify Variables” and ”Program Status”
Execute commissioning functions such as ”Start” and ”Memory Reset”
 Display the module status (i.e. for the IM 151-7 CPU, for example, you can
display the utilization of the load and working memory, stack contents and
diagnostic buffer contents)
You can use the OP to:
 Operate and monitor
You will find a detailed description of the functions in the online help for STEP 7.
Running the IM 151-7 CPU as a passive I slave on the PD – required settings in
STEP 7
If you connect an IM 151-7 CPU directly to a PD, you must set the PD interface in
STEP 7 to allow communication between the two partners. Proceed as follows:
1. In STEP 7, choose the ”Set PD/PC Interface” tool (Start > STEP 7 > Set
PD/PC Interface).
2. Set the interface of your PD to PROFIBUS.
3. Call the properties of the PROFIBUS network.
4. Set the properties so that the PD/PC is the only active master on the bus.
If you subsequently configure a DP master for the network and want to go online,
you should cancel these settings; additional security functions are thus activated
against bus faults.
