Checked item
Is there any other job that is being
executed?
Has an error or job cancellation occurred
during job execution?
Is there any setting that enables data
writing to the tag component for which
statistical processing of [Moving average],
[Moving maximum], or [Moving minimum] is
specified in the job?
Has trigger buffer full occurred?
Check if 'Information linkage status (X5)' is
in execution (ON).
During one-shot execution, was the power
of the programmable controller turned OFF
and then ON, or was the programmable
controller CPU reset?
Has a communication error occurred during
one-shot execution?
Has an error occurred in [Error log] of
[Working log]?
Section 7.12.5 Checking the
working log of the MES interface
module
®
Was the Windows account specified in
[Server service settings] used to log on the
application server computer once or more?
Was the password of the Windows
account specified in [Server service
settings] set empty?
Does the program need to be run with
administrator privileges (by a user in
Administrators group)?
Was execution of a program including
displays attempted with the application
server computer logged off?
Corrective action
• Terminate the job that is in execution, or use another
[Server service settings] item.
Section 7.9 Server Service Setting
• If a job uses the same [Server service settings] item
that is currently used for another job, the job is not
executed until another job execution is completed.
• If an error has occurred, identify the error cause and
take corrective actions.
Section 10.2 Error Code List
• When the job uses a tag component for which
[Moving average], [Moving maximum] or [Moving
minimum] is specified, check if sampling for the
specified number of times is completed.
• Check the [Job settings] and disable data writing to
the relevant tag component.
• Correct the setting so the trigger interval is longer
than the processing time of action.
Section 6.1.5 Trigger buffering function
• When using 'Value monitoring startup' or
'Handshake operation' for a trigger condition, check
that 'Information linkage status (X5)' is in execution
(ON), and create a program so that the trigger
condition is satisfied.
• Write a project again and perform [Update settings].
Section 7.15 (4) One-shot execution
• If an error has occurred, identify the error cause and
take corrective actions.
Section 10.2 Error Code List
• Use the account that has been used to log on once
or more.
• An account that has not been used before cannot be
used.
• Set a password of the account, or use another
®
account that does not have an empty password.
• An account that has an empty password cannot be
used.
• Programs that need to be run with administrator
privileges (by a user in Administrators group) cannot
be executed.
• Specify a program that does not need to be run with
administrator privileges.
• To execute a program including displays, set the
application server computer into the logon status.
