Fault/error display
6-8
Alarms A081 and A088 are also stored for information purposes in
alarm parameter 6 (r958). The individual alarms are assigned to the
corresponding bits in r958 (Bit x = 1: alarm present):
9 8 7
A second CB uses the bits 8 to 15 of r958 and the warnings A089 to
A096.
When the CBL is combined with the control/technology board (CU/TB),
the following fault messages may occur:
Fault
F 080 TB/CB Init.:
Incorrect initialization and parameterization of the CBL via the
dual-port RAM interface (DPR interface)
•
Parameterization for CBL false, cause of incorrect
parameterization in diagnostic parameter r732.01
⇒
Correct CB parameter P711-P718.
⇒
Correct CB bus address (CC-Link) P918.
•
CBL defective
⇒
Replace CBL
F 081 DPR heartbeat:
The CBL is no longer processing the heartbeat counter.
•
CBL not correctly inserted into the electronics box
⇒
Check CBL
•

F 082 DPR telegram failure:
The telegram-failure time set by means of parameter P722 has
expired.
•
PLC (bus master) failed (green LED on the CBL is
continuously off)
⇒
Check PLC (cpu and CC-Link master)
⇒
Check cable
•
Connection between the bus nodes has been interrupted
(green LED on the CBL is continuously off, RUNLED, SDLED
and RDLED are continuously off)
⇒
Check the bus cable
⇒
Check PLC (CC-Link master)
•
EMC loading of the bus cable too high (ERRLED flashes)
⇒
Refer to EMC notes
•
Telegram monitoring time has been set too low (green, yellow
and red LED on the CBL flashes synchronous)
⇒
Increase the parameter value in P722
•
CBL defective
⇒
