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.
