Error details
The specified module of the extension base unit
cannot be replaced online since it is connected
to the standby system.
The specified start I/O number is outside the
range.
An online module change request is abnormal.
An online module change is already being made
for other equipment.
The specified start I/O number differs from the
one registered for online module change.
The specified module differs from the one
changed online.
The specified module does not exist.
The specified module is faulty.
There is no response from the specified module.
The specified module is incompatible with online
module change.
The specified module is mounted on the
extension base unit of the type that requires no
power supply module.
The specified module is not in a control group.
An error occurred in the setting of the initial
setting parameter of the intelligent function
module.
Cannot be executed as the parameter file has
been rewritten.
System switching occurs during the online
module change.
The information of the online module change
cannot be sent to the standby system. When the
system switching occurs during the online
module change, the online module change may
not be continued.
The module mounted on the extension base unit
cannot be replaced online when the connection
destination is set to the standby system in the
separate mode.
The number of characters exceeded the valid
range when registering the e-mail addresses by
using the SP.MLOPEADR instruction.
Corrective action
Change the connection destination to the control
system and perform the online module change
again.
When making a request, specify the start I/O
number of the module that will be changed online.
Check the command used to make a request.
Make a request again after completion of the
online module change, or continue after changing
the connection path.
When making a request, specify the start I/O
number of the module being changed online.
Make a request again after mounting the module
that is the same as the one changed online.
When making a request, specify the start I/O
number of the module that will be changed online,
or make a request again after mounting the
module.
Make a request again after changing the module.
Continue the online module changing operation.
Do not make a request where an error occurred, or
make a request again to the module compatible
with online module change.
Do not make a request to any modules mounted
on the extension base unit of the type that requires
no power supply module and the main base unit.
Make a request to the CPU module that controls
the specified module.
Resume processing after checking the contents of
the intelligent function module buffer memory.
Operation cannot be performed. Operation is
interrupted.
Connect the programming tool to the new control
system to check the status of the online module
change. According to the status of online module
change, take procedures for it.
The tracking cable may be faulty or the standby
system may have an error.
• Check the mounting status of the tracking cable
or replace the tracking cable.
• Check the status of the standby system. When a
stop error was detected by the standby system,
perform troubleshooting.
• Set the connection destination of a programming
tool to the present control system.
• Perform the online module change to the
module mounted on the extension base unit
again.
Reduce the number of e-mail addresses to be
registered.
