10 Causes of faults and remedies
10.1 Optical displays
LED allocation see chapter “Bus status display” on page 96.
Voltage supply absent or too low
- Check voltage supply, wiring
- Is the voltage supply in the permissible range?
Hardware error,
measuring system defective
Measuring system ready for
operation, Ethernet connection
established, data transfer active.
Measuring system ready for
operation, Ethernet connection
established, no data transfer.
Not powered or
no IP address obtained
- Check voltage supply, wiring
- Is the voltage supply in the permissible range?
- Use one of the possibilities, in order to obtain the IP
address:
Configuration via hardware switches, see page 95
Configuration via FLASH, see page 135
Configuration via DHCP, see page 135
No connections established,
but an IP address was
obtained.
- Try to read the status of the Identity Object to
restrict the error possibilities.
- Control could not establish a connection due to faulty IP
parameters. Check IP address, Subnet mask and
Default Gateway adjustments between control and
measuring system.
- Control could not establish a connection due to faulty
link parameters. Check control adjustments regarding to
Class code, Instance and Attribute-ID (Connection Point,
Object 0x04 Assembly).
Measuring system in operation, normal operating state
Self-test, while power up.
One or more of the connections
in which the device is the target
has timed out.
This state is left only if all timed out connections are re-
established or if the device is RESET.
The device has detected that its
IP address is already in use.
Guarantee that the IP address is only once assigned
within an EtherNet/IP™ segment.
Self-test, while power up.
