7.3 Commissioning and startup of the IM 151-7 CPU as an
I slave
An example of how to commission the IM 151-7 CPU as an I slave and its behavior
when it starts up is described below.
Information on how to commission the IM 151-7 CPU as the DP master is found in
Chapter 6.2.
Chapters 2.4, 5.2 and 8.5 contain information on stand-alone operation.
Prerequisites for commissioning
The DP master (either an S7 DP master or another DP master) has been
parameterized and configured.
All other DP slaves have been parameterized and configured.
Commissioning the ET 200S
Commission the ET 200S distributed I/O system as follows:
1. Install the ET 200S distributed I/O system
(see the ET 200S Distributed I/O System manual).
2. Wire the ET 200S distributed I/O system
(see the ET 200S Distributed I/O System manual).
3. Assign a PROFIBUS address (see Chapter 4.3) and a slave diagnostic address
(see Chapter 3.3) to the IM 151-7 CPU.
4. During configuration as an I slave, specify in the configuration software the
address areas in the IM 151-7 CPU via which data exchange with the DP
master is to take place (or use the ET 200S default setting; see Section 3.4).
5. Switch on the sensor supply voltage for the ET 200S.
6. If necessary, switch on the load voltage and the supply voltage for the motor
starters.
7. If necessary, switch the IM 151-7 CPU to STOP mode.
8. Download the configuration for the IM 151-7 CPU to the ET 200S.
9. Switch the IM 151-7 CPU to RUN mode.
Starting behavior of the IM 151-7 CPU
On starting the IM 151-7 CPU following POWER ON, make sure that
the terminating module is connected
all terminal modules connected to the IM 151-7 CPU are fitted
Otherwise the IM 151-7 CPU will remain in the START mode.
