36.4 List of Error Codes
Error details and cause
• In a redundant system with redundant
extension base unit, an interrupt
pointer has been set to modules
mounted on an extension base unit.
(The error is detected in the control
system or the standby system.)
• In a redundant system with redundant
extension base unit, the number of
slots on the redundant extension base
unit is set to nine slots or more in the
system parameter (I/O assignment
setting). (The error is detected in the
control system or the standby
system.)
• The program includes an instruction
that cannot be used in the operation
mode set in the engineering tool.
• In the CPU module, which does not
support SFC programs when
operating in redundant mode, SFC
programs are set in the CPU
parameters ("Program Setting").
• In a redundant system with redundant
extension base unit, the system
switching was performed when the
online module change is in progress
on the main base unit of the control
system. (The error is detected in the
standby system.)
• The operation of the standby system
has been suspended because the
memory copy function has been
executed.
Stop/ Action
continue
Stop • Check the detailed information
(parameter information) of the
error by executing module
diagnostics using the engineering
tool, correct the parameter setting
corresponding to the displayed
number, and delete the setting of
the interrupt pointer for modules
mounted on an extension base
unit.
Stop • Check the I/O assignment setting
in the system parameter, correct
the number of slots on the
redundant extension base unit to
eight slots or less.
Stop • Check the detailed information
(error location information) of the
error by executing module
diagnostics using the engineering
tool, display the error program
(step) by clicking the [Error Jump]
button, and delete the program.
Then, write the program to the
CPU module again.
Stop • Replace the CPU module with the
one supporting SFC programs in
redundant mode.
• Check the detailed information
(drive/file information) of the error
by executing module diagnostics
using the engineering tool, and
delete all SFC programs
registered. Then, write CPU
parameters to the CPU module
again.
Stop • Power off the standby system and
change the modules. Then, power
on the standby system.
Stop • Power off and on or reset the CPU
module after the memory data has
been copied from the control
system to the standby system.
