3.2 Function List of an MES Interface Module
Description
Device memory input A function to read data in the device memory.
function Data used for trigger judgment is read, and then data used for job is read.
Device memory output A function to write data written in the device tag in the job to the device
function memory.
DB record input/output A function to read/write data in the database of the host information system.
function
DB buffering function 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.
System variable input/ A function to read/write data of the system variable storing operating status of
output function the module such as the status of an MES interface module.
User variable input/ A function to read/write data to a user variable (local variable/global variable)
output function which can be registered arbitrarily.
• Local variable: can be used in a same job
• Global variable: can be used between jobs
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 basic arithmetic operations, remainder, and character string operation of device
tag component values.
Data assignment A function to assign and link the device tag, DB data, and variable which are
function read by using the data input/output function.
A function to check the communication settings between a MES interface module and access target
device or access target server.
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 manual.
