Error
Possible error cause
Measure
PWR LED "OFF"
No supply voltage connected
Check supply voltage.
Hardware error
Send in device.
PWR-LED "flashes red"
Light beam interruption
Check alignment.

General causes of errors
Error
Possible error cause
Measure
BUS LED "OFF"
No supply voltage connected to the device
Check supply voltage.
Device not yet recognized by the PROFINET
Send device to customer service.
Hardware error
BUS LED "flashes red"
Incorrect wiring
Check wiring.
Communication error: parameterization or configu-
ration failed ("parameter failure")
IO Error: no data exchange
• Check configuration, in particular with respect to
address assignment (device names/IP address/
MAC ID).
• Carry out a reset on the control.
BUS LED "static red"
Incorrect wiring
Check wiring.
Communication error on the PROFINET.
No communication established to the controller (no
data exchange)
• Check protocol settings.
• Check configuration, in particular with respect to
address assignment (device names/IP address/
MAC ID).
Different protocol settings
Check protocol settings.
Protocol not released
Activate TCP/ IP or UDP.
Wrong device name set
• Check configuration, in particular with respect to
address assignment (device names/IP address/
MAC ID).
Incorrect configuration
• Check configuration, in particular with respect to
address assignment (device names/IP address/
MAC ID).
• Send device to customer service.
Sporadic
network error
Check wiring for proper contacting
Check wiring,
• In particular, check wire shielding.
• Check wires used.
EMC coupling
• Observe contact quality of screwed or soldered
contacts in the wiring.
• Avoid EMC coupling caused by power cables laid
parallel to device lines.
• Separate laying of power and data
communications cables.
Network expansion exceeded
Check max. network expansion as a function of the
max. cable lengths.
