Set the tag components or CompactFlash card capacity for DB buffering function.
For the setting methods, refer to the following:
Section 7.6.4 Setting items in DB buffering setting
Set whether to enable the DB buffering function for each job.
When enabling the DB buffering function, select the type of DB buffer.
For the setting methods, refer to the following:
Section 7.10.4 Setting items in DB Buffering
There are two types of buffering areas; Automatically resend buffer and Manually
resend buffer.
Use the Automatically resend buffer if resending the data automatically after
recovery.
Use the Manually resend buffer if resending the data with a desired timing.
Table 6.2 Automatically resend buffer and Manually resend buffer
Type
After recovery, data is resent automatically.
After recovery, the data is resent by executing the following operation.
• Resend request from [MES interface function configuration tool] - [Remote operation]
• Resend request from the specified tag component in [Resend DB buffer request]
The operation after recovery can be set for each resend buffer whether to send
the job whose trigger condition has been met immediately in case the data exists
in the resend buffer or to send the buffered data after the resend completion.
Table 6.3 Operation of recovery from network disconnection
Send the data immediately.
After recovery, the job whose trigger condition has been met is sent to the database
before the data remaining in the resend buffer.
After recovery, the job data is being added to the bottom of the buffered data until the
resend operation is completed.
The data is sent to the database in order of the trigger condition has been met.
For setting methods, refer to the following:
Section 7.6.4 (8) Operation of recovery from network disconnection
