In the panel window, the error numbers follow E in the display.
Error No. Error name Description, action, etc.
548 IA Net resizing overlapping error Several stations executed the resizing.
There is a concern multiple stations are subject to resizing
execution.
Check the conformity of I/O parameter No. 603 with the
controller on the same network.
54C IA Network communication
parameter error
There is an error in the communication parameter of IA
Network. Check in I/O Parameter No. 601 to 606.
552 IA Net link error IA Net link error was detected.
Confirm that all the controllers occupying the stations
indicated in I/O parameters No. 603 and 604 are
connected properly to IA Net.
This error also occurs when the occupied stations
indicated in I/O parameters No. 601 and 602 are
duplicating with other controllers connected to IA Net.
553 IA Net message command
sending busy error
Message command could not be sent due to the busy
condition at the process of IA Net message command
sending.
554 IA Net message command
sending timeout error
IA Net message command could not be completed to be
sent in the specified time.
There is a concern of message commands not being able
to be sent properly.
556 IA Net message command
domain access right acquirement
timeout error

not be gained in the specified time.
560 Number of IA Net occupied station
exceeded error
The number of IA Net occupied stations has exceeded the
number allowed in the system.
561 IA Net I/O assignment number
overflow error
The number of IA Net I/O assignments has exceeded the
specified range.
562 Extension I/O unit parameter error There is a failure in the extension I/O unit parameters.
1) The station numbers for a controller and an extension
I/O unit are duplicated.
2) Eextension I/O unit with a station number greater
than the value set in I/O parameter No. 604 “IA Net
final station number” is attempted to be used.
563 Extension I/O unit DO duplication
error
Multiple controllers attempted to use DO in one I/O board
on the extension I/O unit.
564 Extension I/O unit initial
Communication timeout error
Initial communication with the extension remote I/O unit
was not established correctly.
It could be considered that;
1) Extension remote I/O unit is not connected.
2) Power is not supplied to extension remote I/O unit.
3) Wrong unit number is set in I/O parameters.
565 Extension I/O unit board
undetected error
I/O board in an extension I/O unit was not detected.
566 Extension I/O unit undefined error
code detection
Undefined extension I/O unit error code was detected.
This error occurs when the main CPU board software is
not applicable for the error code of the extension I/O unit.
Updating is required on the application in the main CPU
board.
567 IA Net communication cycle time
error
There is an error in the communication cycle time of IA
Net.
568 Extension I/O unit self checking
error
There is a failure in the CPU program of extension I/O
unit.
Cold-start level errors
569 Extension I/O unit initial
communication parameter error
There is a failure in the extension I/O unit parameters.
Make sure that the I/O parameters No. 20 and 716, etc.,
are identical to those of the other extension I/O unit
controller.
