9.1.3 Assigning Parameters in DB1

As discussed in section 9.1.2, you use the following steps to change or expand the preset values of
DB1:
1. Display the default DB1, with its parameter block "ERT:" on the programmer.
2. Position the cursor on the desired parameter block.
3. Change or expand the parameters.
(for an explanation and possible parameter values see section 9.1.7)
4. Transfer the changed DB1 to the programmable controller.
5. Switch the programmable controller from STOP to RUN.
Changed DB1 parameters are accepted.
Note
If the CPU recognizes an error in DB1, then it remains in the STOP mode (red LED
lights up) even after a switch from STOP to RUN.
