Starting And Operating The Et 200 - Siemens SIMATIC S5 Manual

S5-95U – starting ET 200

12.1 Starting and operating the ET 200

Preconditions
Starting the ET 200

We assume:
that you have installed a backup battery in each S5-95U with DP master
interface.
that you have inserted the 32 K EEPROM(s) in the S5-95Us with DP
master interface (see Section 4.5).
that you have used COM ET 200 Windows to transfer the data of each
master system to the appropriate DP master (see Section 8.4.2).
that you have checked the configuration of the distributed I/O system.
When you are ready to start the ET 200 distributed I/O system:
1. Test the wiring to the sensors and actuators of the individual DP slaves:
For example, you can use the ET 200 handheld to run the status/control
function for each DP slave and read the diagnostic report. The ET 200
handheld is described in a separate manual. The order number for this
manual is 6ES5 998-7ET.1.
Result: After testing the DP slaves, you are sure that each DP slave is
fully operational.
2. Connect all DP slaves and DP masters with the L2 bus cable.
3. Switch on the power supply units of the DP slaves.
4. Set the STOP/RUN switches of the DP slaves (if fitted) to RUN.
5. Switch on the power supply of the S5-95U with DP master interface.
6. Set the ON/OFF switch on the S5-95U to "I".
7. Switch the S5-95U programmable controllers with DP master interface
from STOP to RUN.
Result: The S5-95Us power up. On the S5-95Us and the connected DP
slaves the "BF" LEDs go out. Data exchange is possible between all
parameterized DP slaves and the S5-95U.
Figure 12-1 is a flowchart illustrating the power-up sequence of the
S5-95U on the bus.
8. Use the FB 230 to check the diagnostic messages. These messages will
tell you whether or not data exchange with the DP slaves is functioning
correctly.
9. Via the PG interface of the S5-95U, you can execute the status/control
function for all DP slaves the addresses of which are contained in the
process image.
To run this function, you must know which addresses in the STEP 5
application program are assigned to the inputs and outputs of the DP
slaves.
