5.
The TIM can then be supplied with its parameters over the MPI interface of the CPU or its
own Ethernet interface.
Note
If the TIM 4R-IE is installed as a CP in an S7-300 and the CPU is of the type CPU 312,
CPU 312-C, CPU 313-C, CPU 314, CPU 314-C, CPU 315-2 DP or CPU 315F-2 DP, the
TIM is assigned the MPI address 3 following a default startup. If another subscriber on
the MPI bus already has MPI address 3, a conflict will arise. You will then have to
disconnect one of the two modules temporarily from the MPI bus to be able to transfer the
parameters (including the correct MPI address) to the TIM.

Restart the TIM on completion of the parameter assignment.

Startup behavior of the TIM 4
Introduction
During startup, the meaning of the LEDs on the front panel of the TIM 4R / TIM 4RD is
different from the meaning during normal operation. They are optical indicators of the various
startup phases and provide detailed information about any errors detected during startup.
LED displays during startup
The following table summarizes the startup phases.

Phase
Activity
Explanation
1
Power ON
All LEDs light up at the same time.
2
RAM test
Starting with LED 6 (DCF77), the LEDs go off one after the other at intervals of
approximately 10 seconds. If an error is detected during the RAM test, LED 1 (SF
group error)
remains lit at the end. If everything is OK, the TIM changes to phase 3.
3
Service mode
After all the LEDs have gone off, all LEDs light up again for 5 seconds. During this time,
the user can force a default startup (see below) using the reset button. Otherwise, the
TIM changes to phase 4.
4
Software startup
All the LEDs go off again and then light up again one after the other starting with LED 2
(TXD). At this stage of startup, the individual steps of the software startup are signaled
by the LEDs. The LEDs are either lit continuously or flash. The following table lists the
exact meaning of the individual LEDs when lit continuously or flashing during this
startup phase 4.
5
Startup completed
The LEDs go off if phase 4 is completed free of errors and then have the significance
according to their definition in normal operation.
