Fault detection configuration
If an invalid value or an invalid combination of parameter values is
detected in the CB parameters, the converter switches to fault mode
with fault F080 and fault value 5 (r949). The cause of the incorrect
parameterization can then be determined by means of the CB
diagnostic parameter r732.
Value
(hex)
00 No fault/error
01 Incorrect CC-Link address (P918)
02 Incorrect transmission rate (P711)
03 Incorrect scaling parameter in P715 (parameter number > 3999)
04 Incorrect scaling parameter in P716 (parameter number > 3999)
05 Incorrect scaling parameter in P717 (parameter number > 3999)
06 Incorrect scaling parameter in P718 (parameter number > 3999)
07 Incorrect softwiring in REF VALUE channel (double words routed)
08 Incorrect softwiring in ACT VALUE channel (double words routed)
09 Incorrect configuration sequence

Table 6-19 CBL diagnostics buffer: configuration error
Counter received telegrams without fault; ONLINE
Counter for telegrams received error-free with data transfer between
PLC and CBL.
Counter received telegrams without fault; OFFLINE
Counter for telegrams received error free with no data transfer
between PLC and CBL. Reason:
• PLC in status stop or fault. CC-Link master still polling.
• PLC running; CBL is waiting for complete initial process
sequence (acknowledge by PLC).
Counter overrun
Counter of receiver overrun; receive and transmit handling in CBL is
not finished until next data polling.
Counter underrun
Counter for transmitter underrun; transmitter is not fast enough to
send newest transmit data.
Counter CRC errors in receiver
Counter for data transmission errors (crc errors) in receive data.
Counter timeout
Counter for timout in polling sequence to CBL; CBL didn't receive any
faultless data frame in a defined time period.
