Restart After Update
Update via PROFIBUS DP
In the
STEP 7
user interface, it is possible to set whether
● the IM 153-2 should automatically perform a reset after a successful update, in order to
start off using the new firmware.
CAUTION
If the "activate firmware after download" field is checked there is a brief station failure of
the ET 200M. If no provisions have been made for this case, then the update causes the
CPU to STOP on account of rack failure.
● the IM 153-2 must be reset by switching off the supply voltage. Then, when the supply
voltage is switched on again the IM 153-2 will start up using the new firmware.
Update via SIMATIC Micro Memory Card
After the update the IM 153-2 remains in a state that can only be reset by switching off the
supply voltage. After a successful update, the next time the supply voltage is switched on the
IM 153-2 starts up with the new firmware.
Update unsuccessful
If the update fails, the next time the supply voltage is switched off / on the IM 153-2 starts up
with the former (old) firmware.
