6.2 Errors detected by CC-Link master station

The errors detected by CC-Link master station (detected by the reply data from BIF-CC) are shown in table 6.2.

16 10h Hardware error has occurred.
64 40h The command number is outside the range.
65 41h The data group number is outside the range.
66 42h The data channel number is outside the range.
69 45h The unit number is outside the range.
The setting data set by setting command is
81 51h
outside the range.
■1): About the errors other than described above, refer to manual of master station.
■2): When the power supply of BIF-CC is turned on under the state that the power supply is not supplied to ETR, the CC-Link communication is
not started for 1 minute. After 1 minute, CC-Link communication will start, but internal transmission error will occur (T ERR. LED blinks).

☐ Check the power supply of Power supply
module
(P1-P5).
☐Check that there is no wire breakage in the
internal transmission cable.
☐Check that the internal transmission cable is
wired properly.
☐Check that the kinds of CC-Link cable, overall
distance,
terminal
resistor are within the specified range.
☐Check for wire breakage, a short, reversed
connection of CC-Link cable.
☐Earth the FG terminal of BIF-CC without fail.
☐Check that the STATION NO. or B RATE switch
is not outside the setting range.
☐Switch power on again.
☐Check whether the internal transmission error
check the following:
☐Power supply of Power supply module (P1-P5).
☐There is no wire breakage in the internal transmission cable.
☐The internal transmission cable is wired properly.
☐After correcting the command number, send data again.
☐After correcting the data group number, send data again.
☐Correct the data channel number and send data again, if it has mistaken.
☐Check the power supply of Power supply module (P1-P5).
☐Check that there is no wire breakage in the internal transmission cable.
☐Check that the internal transmission cable is wired properly.
☐After correcting the unit number, send data again.
☐After correcting the setting data, send data again.
