Distributed I/O Device ET 200M

Update in the Redundant System

If the update of the active IM 153-2 is performed via PROFIBUS-DP, the reset

which is performed afterwards automatically triggers the switchover between the

two IM 153-2 modules. We recommend that you then also update the second

IM 153-2 in the redundant system. The update must be performed separately for

each IM 153-2.

Restart After Update

Update via PROFIBUS-DP

In the STEP 7 user interface, it is possible to set whether

 the IM 153-2 performs a reset automatically on completion of the update in

order to start up with the newly loaded firmware

Caution

If the ”Update Firmware After Loading” box is selected, there will be a brief station

failure of the ET 200M. If no precautions have been taken to counter this, the

update causes the CPU to enter STOP mode owing to rack failure.

 the IM 153-2 is to be reset by switching off the supply voltage before the

IM 153-2 starts up with the new firmware when the supply voltage is switched

on again.

Update via MMC

On completion of the update, the IM 153-2 remains in a state which can only be

left by switching off the supply voltage. If the update was successful, the IM 153-2

starts up with the new firmware the next time the supply voltage is switched on.

Update Not Successful

If the update is unsuccessful, the IM 153-2 always starts up with the currently

loaded (”old”) firmware when the supply voltage is switched off and then on again.
