Safe-state mode

Function of the safe-state mode

If the device does not work as intended, e.g. as a result of errors in the project design
or during commissioning, the execution of the loaded application program can be hal-
ted by activating the safe-state mode. In safe-state mode, essential functions of the
device are deactivated. Only the ETS diagnosis function can be executed, and it is
still possible to program the device.

When safe-state mode is active, the device acts as follows:

–

No group telegrams, physically addressed telegrams or broadcast telegrams
are forwarded (the routing is inactive).

–

The repeater function is inactive (no RF telegrams are repeated).

–

The configuration lock is inactive.

–

The status LED flashes red slowly.

If the device is working exclusively as a repeater (physical address
x.y.1...255), it is only possible to program the application program and read out
device information via the RF side! Thus, the configuration lock is always act-
ive on the TP side. In this case, the lock cannot even be released in safe-state
mode.

Activating the safe-state mode

￭

Disconnect the device connection terminal.

￭

Hold down the programming button.

￭

Reconnect the device connection terminal.

The device restarts. The status LED briefly lights up red and then yellow.

￭

Release the programming button as soon as the status LED starts flashing red
slowly.

Safe-state mode is active.

Deactivating safe-state mode

Safe-state mode is deactivated via the ETS or by disconnecting and reconnecting the
device voltage supply.

Precondition: Safe-state mode is active.

￭

Reset the device via the ETS (restart).

or

￭

Program the physical address with the help of the ETS.

or

￭

Disconnect the device connection terminals or switch off the voltage supply.

￭

Wait about 3 s.
