How to Proceed:
Perform an overall reset on the programmable controller.
Display the default DB1 on the programmer.
Position the cursor on the E of the ”END” ID at the end of the default DB1.
Enter the characters, including the blanks, that are highlighted in Figure 9-15.

Use the following check list to make sure your entries are correct.
Transfer the changed DB1 to the programmable controller.
Now you can switch the programmable controller from STOP to RUN
.
If you have proceeded as described above, the PLC will carry out the following steps automatically:
1. The PLC parameterizes DB1 when changing from STOP to RUN mode.
2. If DB1 does not contain any errors, the PLC transfers the parameters of DB1 into the system
data area. In this case, the "ERT:" parameter block is meaningless. Flag words 2 to 20 are
assigned "0".
If DB1 is errored, the PLC remains in the STOP mode and writes the cause and location of the
error into the flag word appearing behind the parameter name "ERR_". In the example, cause
and location of the error will be entered in MW2.
If your DB1 contains several errors, they are stored in the subsequent flag words. Up to ten
errors are stored, i.e. you have make provisions for 10 flag words. In the example, MW2 up to
and including MW20 are used.
