files and starts the update.
– During the update the SF and the BF LEDs light up.
– After the update is concluded the BF LED flashes at 0.5 Hz.

Update in the Redundant System
When the update of the active IM 153-2 takes place via PROFIBUS DP, the concluding reset
automatically triggers the changeover procedure between the two IM 153-2s. We
recommend that you then carry out an update of the second IM 153-2 in the redundant
system. The update must be conducted separately for each IM 153-2.
