current startup phase.
Group error LED
If an error occurs during startup, the red group error LED (SF) lights up and, if the TIM 4 is
installed as a CP in an S7-300 rack, a diagnostic interrupt is sent to the CPU. A message to
this effect is also entered in the diagnostic buffer of the TIM 4. In the chapter on the SINAUT
Diagnostics and Service tool, you will find a table with a summary of all the errors that can
cause the group error LED to light up, as well as a detailed description of each error
message.
Note
After transferring the SDBs to the TIM, the group error LED flashes for approximately 10
seconds. This indicates that the TIM has registered the transfer and will automatically start a
reset after a further 10 seconds and the parameter assignment from the newly transferred
SDBs will be adopted. The TIM then behaves the same as following power "ON".
Default startup
If the situation arises that the TIM 4 can no longer be addressed over the MPI bus following
startup due to a bad parameter assignment, the TIM can be returned to a defined state using
the default startup. Following the default startup, the TIM can be assigned new parameter
settings over the MPI bus.
To force a default startup, follow the steps outlined below:
1.
Press the reset button accessible from below until all the LEDs on the TIM light up.
2.
Follow the various startup phases of the TIM based on the LED display.
3.
During startup phase 3 (service mode, see table), press the reset button again until all the
LEDs on the TIM light up.
4.
Wait until the startup of the TIM is completed and the default startup is signaled by the
LEDs.
