[BASE LAY ERROR]
The QA1S3B, QA1S5B, QA1S6B,
QA1S6ADP+A1S5B/A1S6B, QA6B, or
QA6ADP+A5B/A6B was used as the base
unit.
2011
■Collateral information
• Common information: Base No.
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[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
2012
with the extension base unit.
• The Q5B, QA1S5B, QA1S6B,
QA1S6ADP+A1S5B/A1S6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
[BASE LAY ERROR]
Stage number of the Q6WRB is recognized as
other than extension stage No.1 in the redundant
system.
2013 ■Collateral information
• Common information: Base No.
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[BASE LAY ERROR]
The branch module on the block before the
LA1S5B is connected on the left of the END
cover.
2014
■Collateral information
• Common information: Module No. (Block No.)
• Individual information: -
■Diagnostic timing
• At power-on/At reset
[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
2020
path to the Q6WRB in the END processing.

Corrective action
Do not use the QA1S3B, QA1S5B,
QA1S6B, QA1S6ADP+A1S5B/A1S6B,
QA6B, or QA6ADP+A5B/A6B as the
base unit.
• 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, QA1S5B,
QA1S6B,
QA1S6ADP+A1S5B/A1S6B, QA6B,
or QA6ADP+A5B/A6B as 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.
The cause is a hardware failure of the
Q6WRB. Please consult your local
Mitsubishi representative.
• Replace the LA1S5B with the LA1S6B.
• Connect the branch module on the
LA1S5B on the right of the CPU module
or the extension module.
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.
