36.4 List of Error Codes
Error details and cause
• A multiple CPU system was
configured with CPU modules
incompatible with multiple CPU
systems.
• Eight or more extension base units
are connected.
• Any of the following base units is
connected: QA1S3B, QA1S5B/
QA1S6B, QA6B,
QA6ADP+A5B/A6B, or
QA1S6ADP-S1+A1S5B/A1S6B.
• Extension base unit levels are
overlapping.
• An unsupported base unit is
connected.
• A GOT is bus-connected to the Q
series extension base unit.
• An inter-module synchronization
signal error has been detected.
■CPU module
• A module that the CPU module
cannot recognize is mounted.
• In a multiple CPU system, the module
cannot be recognized because the
control CPU setting in the system
parameters is different from that of
other CPU modules.
■Redundant function module
• Data communications with the CPU
module cannot be performed.
• No extended SRAM cassette is
inserted.
• The capacity of extended SRAM
cassette set in does not match
"Extended SRAM Cassette Setting" in
the CPU parameter with the actual
capacity of the cassette inserted.
Stop/ Action
continue
Stop • Check and correct the system
configuration.
Stop • Reduce the number of extension
base units to seven or less.
Stop • Remove the inapplicable base
unit: QA1S3B, QA1S5B/
QA1S6B, QA6B,
QA6ADP+A5B/A6B, and
QA1S6ADP-S1+A1S5B/
A1S6B.
Stop • Check and correct the level setting
of the extension base units.
Stop • Check the firmware version of the
CPU module, and replace the
CPU module with the one
supporting the use of redundant
extension base units.
• Disconnect the unsupported base
unit. If all the base units are
supported, the possible cause is a
hardware failure of the CPU
module or base unit. Please
consult your local Mitsubishi
representative.
• Disconnect the GOT bus-
connected to the Q series
extension base unit.
Stop • The possible cause is a hardware
failure of the CPU module, base
unit, or module (I/O module or
intelligent function module)
connected. Please consult your
local Mitsubishi representative.
Stop ■CPU module
• Mount only applicable modules.
• Correct the system parameter
settings for the CPU No.2 and
later in accordance with those of
the CPU No.1.
• The possible cause is a hardware
failure of the I/O module or
intelligent function module
accessed. Please consult your
local Mitsubishi representative.
■Redundant function module
• The possible cause is a hardware
failure of the CPU module. Please
consult your local Mitsubishi
representative.
Stop • Check that an extended SRAM
cassette is inserted. Or, correct
the capacity set in "Extended
SRAM Cassette Setting" in the
CPU parameter so that it matches
with the actual capacity of the
cassette inserted. If the same
error code is displayed again, the
possible cause is a hardware
failure of the CPU module or
extended SRAM cassette. Please
consult your local Mitsubishi
representative.
