Off Off Off Off There is no voltage applied to the
IM 153-2, or the IM 153-2 has a
hardware defect.
Switch on the power supply module
or change the IM 153-2.
* * * On There is voltage applied to the IM
153-2. IM 153-2 is in operation.
–
On Off Off Off IM 153-2 is in hardware reset
following power on
–
On On On On Hardware test following power on –
On On Off Off Operating system update is running –
Off Flashes
0.5Hz
Off Off Operating system update has been
completed successfully (remove
MMC and switch on IM 153-2)
–
On Flashes
0.5Hz
Off Off External fault; e.g. unsuitable
operating system or MMC has been
removed
Use a suitable operating system for
the update.
Do not remove the MMC during the
update.
On Flashes
2Hz
Off Off Internal fault; e.g. during writing of the
update files
Repeat the update procedure.
If the LEDs indicate the fault again,
the internal memory is faulty.
* Flashes Off On The IM 153-2 is incorrectly
parameterized – there is no data
transfer between the DP master and
the IM 153-2.
Causes:
The PROFIBUS address is
incorrect
Faults on the bus.
Check the IM 153-2.
Check the configuration and
parameter assignment.
Check the PROFIBUS address on
the IM 153-2 and in the STEP 7
project.
Check the cable length with
respect to the baud rate.
Check the terminating resistor
settings.
