[BASE LAY ERROR]
The GOT is bus-connected to the main base unit
of the redundant system.
The following errors were detected in the
redundant system.
• The base unit other than the Q6WRB is
connected to the extension stage No.1.
• The base unit is connected to any one of the
extension stages No.2 to No.7, although the
Q6WRB does not exist in the extension stage
No.1.
• The other system CPU module is incompatible
with the extension base unit.
•The Q5B, QA1S6B, QA6B or
QA6ADP+A5B/A6B is connected.
• The number of slots of the main base unit for
both systems is different.
• Information of the Q6WRB cannot be read
correctly.
■Collateral information
• Common information: Base No.
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
• Remove the bus connection cable for the GOT
connected to the main base unit.
• Use the Q6WRB (fixed to the extension stage
No.1)
• Use the redundant CPU compatible with the
extension base unit for the other system.
• Do not use the Q5B, QA1S6B, QA6B or
QA6ADP+A5B/A6B for the base unit.
• Use the main base unit which has the same
number of slots.
• The cause is a hardware failure of the
Q6WRB. (Please consult your local
Mitsubishi representative, explaining a detailed
description of the problem.)

[BASE LAY ERROR]
Stage number of the Q6WRB is recognized as
other than extension stage No.1 in the redundant
system.
■Collateral information
• Common information: Base No.
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
The cause is a hardware failure of the Q6WRB.

[EXT.CABLE ERR.]
The following errors were detected in the
redundant system.
• At power-on/reset, the standby system has
detected the error in the path between the
control system and the Q6WRB.
• The standby system detected an error in the
path to the Q6WRB in the END processing.
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset/When an END instruction
executed
Check to see if the extension cable between the
main base unit and the Q6WRB is connected
correctly. If not, connect it after turning OFF the
main base unit where the extension cable will be
connected.
If the cable is properly connected, the cause is a
hardware failure of the CPU module, Q6WRB,
or extension cable. (Please consult your local
Mitsubishi representative, explaining a detailed
description of the problem.)

[NO END COVER]
No END cover.
■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
• Attach an END cover.
• Reset the CPU module and run it again. If the
same error code is displayed again, the cause
is a hardware failure of the CPU module, I/O
module, intelligent function module, or END
cover. (Please consult your local Mitsubishi
representative, explaining a detailed
description of the problem.)
