*1 If cyclic refreshing is not disabled in the PLC Setup for a Special I/O Unit and IORF(097), FIORF(225), IORD(222) or
IOWR(223) is executed for the same Special I/O Unit in an interrupt task, a duplicate refreshing status will occur and an
duplicated refreshing error will occur.
*2 A408 contains the errant rack/slot number.
*3 CJ2H-CPU6@-EIP or CJ2M-CPU3@ only.
*4 The corresponding flag in A417 is turned ON to indicate the problem Unit.
*5 The corresponding flag in A418 to A423 is turned ON to indicate the problem Unit.
*6 The corresponding flag in A427 will be ON.
*7 The corresponding flag in A428 to A433 will be ON.
*8 Executed FAL Number Flags in consecutive bits in A360 to A391 correspond to FAL numbers 001 to 511.
The error code in A400 will indicate the FAL number.
The leftmost digit of the code will be 4 and the rightmost 3 digits of the code will be from 101 to 2FF hex and will corre-
spond to FAL numbers 001 to 511.

Probable cause
An installed Special I/O Unit does not match the
Special I/O Unit registered in the I/O tables.
• A Unit that is specified for synchronous unit
operation does not support synchronous unit

operation.
• A Unit that is specified for synchronous unit
*7
operation does not exist.
A Synchronous Unit that is specified for syn-
chronous unit operation is not on the CPU Rack
(the Synchronous Unit is on an Expansion
*7
Rack).
FAL(006) has been executed in program.
Possible remedy
Change the registered I/O table.
*7
Correct the settings for synchro-
nous unit operation in the PLC
Setup and transfer the PLC Setup
again.
Move the Synchronous Unit to the
CPU Rack. If I/O tables have
been registered, correct the set-
tings in the registered I/O tables.
*8 Correct according to cause indi-
cated by FAL number (set by
user).
