3.2 Function List of an MES Interface Module
Description
Device memory input
function
Device memory output
function
DB record input/output
function
DB buffering function
System variable input/
output function
User variable input/
output function
A function to execute programs on the application server via DB Connection Service.
A function to monitor values of the time or device tag components etc., and start jobs when trigger
conditions are changed from false to true (the condition is satisfied).
A function to control the job execution such as the availability of the job execution depending of the
number of executable jobs at the same time.
A function to buffer information required for the job execution to trigger information as the trigger buffer.
A function to execute arbitrary jobs at arbitrary timing.
A function to perform the substitution
operation of device tag component values.
Data assignment
function
A function to check the communication settings between a MES interface module and access target
device or access target server.
A function to receive a request from MES Interface Function Configuration Tool and access a database,
*2
and acquire DB table names, DB field names, data types of DB fields, stored procedure names, and
argument information of a stored procedure.
A function that allows to perform job-related operations and acquire job information from an REST client.
Also supports the XML process function for the MELSEC-Q Series MES interface module.
A function to prevent illegal access to a MES interface module by setting a user name and password.
A function to format an SD memory card.
A function to diagnose whether an MES interface module operates normally.
A function to replace a module to another without stopping a running system. For the procedure, refer to
the following:
MELSEC iQ-R Online Module Change Manual
*2
A function to update the firmware of an MES interface module.
For details, refer to the following:
MELSEC iQ-R Module Configuration Manual
*2
A function to initialize firmware update prohibition passwords retained in an MES interface module.
A function to read data in the device memory.
Data used for trigger judgment is read, and then data used for job is read.
A function to write data written in the device tag in the job to the device
memory.
A function to read/write data in the database of the host information system.
A function to buffer data sent to the database, and resend it after recovery,
when the data can not be linked due to the disconnection of the network
between MES interface module and the database or failure of the database
etc.
A function to read/write data of the system variable storing operating status of
the module such as the status of an MES interface module.
A function to read/write data to a user variable (local variable/global variable)
which can be registered arbitrarily.
• Local variable: can be used in a same job
• Global variable: can be used between jobs
*1
, basic arithmetic operations, remainder, and character string
A function to assign and link the device tag, DB data, and variable which are
read by using the data input/output function.
