Diagnostics and troubleshooting

If problems should occur during commissioning of the MA 248

you can refer to the following

table. Typical errors and their possible causes are described here as well as tips for their
elimination.

13.1

General causes of errors

Error

Possible error causes

Measures

Data loss
(DL bit)

Data telegram longer than the bus
telegram in bus cycle/memory size.

Increase in bus telegram length.
Toggle out data earlier.

Data in the RS 232
instead of in the
buffer

Incorrect order.

Correct order:
Provide data, toggle CTB.

PWR

status LED on the circuit board

Off

No supply voltage connected to the device. Check supply voltage.
Hardware error.

Send the device to customer service.

Green/orange,
flashing

Device in boot mode.

No valid firmware, send device to cus-
tomer service.

Continuous orange
light

Device error.

Send the device to customer service.

Firmware update failed.

LED on the housing

Green, flashing

Device in service mode.

Reset service mode with webConfig tool.

Red continuous light Network error.

Check interface.
Cannot be rectified by a reset.
Send the device to customer service.

LED on the housing

Red continuous light

Communication error on the PROFINET-IO:
No communication to IO Controller estab-
lished ("no data exchange").

Check interface.
Cannot be rectified by a reset.
Send the device to customer service.
