During the overall reset the entire user memory is erased. Data located in the memory
card is not affected. You have 2 options to initiate an overall reset:
n
Overall reset by means of the operating mode switch
n
Overall reset by means of the Siemens SIMATIC Manager
You should always establish an overall reset to your CPU before loading
an application program into your CPU to ensure that all blocks have been
cleared from the CPU.
4.12.1
Overall reset by means of the operating mode switch
1.
Your CPU must be in STOP mode. For this switch the operating mode switch of the
CPU to STOP.
ð
Status bar:
2.
Switch the operating mode switch to MR position for about 3 seconds.
ð
