BK2000 diagnostic LEDs

Attention must be paid to the fact that there is a connection between the

green I/O LED and the field bus. The I/O LED lights up in connection with

access to the internal K-bus. The green I/O LED does not light up until a

trigger begins via the field bus. This means that the field bus must access

the bus coupler and the controller software must clear a cyclical trigger.

The green I/O LED indicates access to the internal K-bus and is reset after

100 ms.

The bus coupler queries the configuration of the bus terminals after

switching on and does not exchange data with the terminals. That is to say,

the red I/O LED goes off after an error-free startup without the green I/O

LED having to light up. The green I/O LED does not light up until data

exchange is begun via the Beckhoff-Lightbus.

CYC ERR WD Meaning Remedy

off

lit off Bus error (physical). Errored telegrams

are passing through the ring, e.g. fiber-

optic line damaged or previous module

malfunctioning, connector not inserted

correctly.

Check:

whether the fiber-optic cable is inserted

whether the fiber-optic cable has a

discontinuity

whether previous units are operable.

off

off off No operating voltage, severe error; no

functioning

flashing

off off The controller is only occasionally

accessing the bus. The outputs drop out.

Revise the controller software

lit

off off The ring is functioning, but the bus

coupler is not addressed.

Revise the controller software or

allocation list

lit

off lit I/O RUN is not lit, the bus terminal is

addressed, but the data exchange via the

K-bus has not been started.

Add the trigger call to the controller
