7.7 Module replacement

7.7 Module replacement
Startup with configuration data from the SD card
Depending on the use of an optional SD card, the STEP 7 configuration data of the TIM are
stored differently.
● No use of an SD card
The configuration data of the TIM is stored in the work memory of the TIM.
● Use of an SD card
If an SD card is used, the configuration data is stored on the SC card and read from there
each time the TIM starts up.
If the TIM needs to be replaced, this allows simple replacement of the TIM without
needing to download the configuration data again.
If you insert the SD card of the TIM being replaced in the new TIM, when it restarts it
reads the configuration data from the SD card of the replaced TIM.
