Function Description
Reference
section
DB interface function Executes access to the database in units of jobs.
Section 6.1
Section 7.10
Section 7.11
Tag function
Collects device data of the programmable controller CPUs on the network in units of
tags.
By allocating database fields to tag components, the DB interface function enables the
following.
• Database value reading/writing
• Reading/writing of programmable controller CPU device data specified with tag
components
Section 6.1.3
Section 7.8
Trigger monitoring
function
Monitors values such as the time and tag values, and when the trigger condition
changes from false to true (when the conditions are met), starts a job.
Section 6.1.4
Section 7.10.2
Trigger buffering
function
When multiple sets of conditions for data transmission are met in a concentrated
manner, their data and trigger times are buffered in the module's internal memory so that
actions (data operation/transmission) can be executed later using the buffered data.
Even if the frequency of data transmission triggers is high, jobs are executed without
missing any trigger.
Section 6.1.5
Section 7.10.1
SQL text transmission
function
(Communication action)
Automatically creates an SQL text and communicates with the database.
The following commands can be selected for the SQL text.
• Select/MultiSelect
• Update
• Insert
• Delete
Section 6.1.6
Section 7.11.2
Stored procedure call
function
(Communication action)
A function to startup stored procedure in the database. Section 7.11.3
Arithmetic processing
function
(Operation action)
Performs operations for tag component values.
Section 6.1.8
Section 7.11.4
Program execution
function
Executes programs in the application server computer before execution of the first action
and after execution of the last one in a job.
Section 6.1.9
Section 7.10.3
DB buffering function
Buffers SQL texts into a CompactFlash card when they cannot be sent due to network
disconnection or failure of the database server computer.
After recovery, the buffered SQL texts are automatically sent to the database. (Manual
operation is also possible.)
Section 6.1.10
Section 7.6.4
Section 7.10.4
Section 7.13.6
XML processing function
Processes execution of requests made by user applications using XML format
messages.
The XML processing function allows the following instructions for job execution.
• One-shot execution of a job
• Validating a job (The job is executed when the trigger conditions are met.)
• Invalidating a job (The job is not executed even if the trigger conditions are met.)
Section 6.2
CHAPTER 9
Time synchronization
function
Makes the time of the MES interface module synchronized with the time of the SNTP
server computer on the network or a programmable controller CPU (No.1 CPU in the
multiple CPU system).
