1
After holding the switch in the "MRES" position
for 5 seconds, chaser lights of the three LEDs
appear (flashing alternately).
The TIM restarts.
Continue to hold switch.
2
As soon as the three LEDs flash three times
synchronously the TIM is reset. It adopts the
factory settings.
You can release the button:
Startup after resetting to factory settings
After resetting return the switch of the TIM back to the "RUN" position.
The TIM restarts again. For the LED pattern see section Startup - LED pattern (Page 49).
When resetting using the WBM, the TIM starts up again automatically.
The remaining behavior depends on the use of an optional SD card:
●
Startup without SD card
If you do not use an SD card, the TIM starts up without configuration data with an error.
You need to reload the configuration data.
The TIM can be reached via its Ethernet interfaces with default IP address (see above)
set in the factory.
Generally, the defaults apply during the first commissioning, refer to the section
Commissioning (Page 48).
●
Startup with SD card
If the SD card remains inserted, the TIM starts up again with the configuration data on the
SD card.

SNMP
SNMP (Simple Network Management Protocol)
SNMP is a protocol for management and diagnostics of networks and nodes in the network.
To transmit data, SNMP uses the connectionless UDP protocol.
The information on the properties of SNMP-compliant devices is entered in MIB files (MIB =
Management Information Base).
