Access Type - Mitsubishi Electric MELSEC iQ-R Series User Manual

Access type

The following access types can be selected for accessing a database server from an MES interface module.
• Connection via service
• Direct DB connection
Connection via service
A database is accessed via DB Connection Service installed on a database server.
(1)
DB
Ethernet
(3)
(1) Database server
(2) DB Connection Service
(3) MES interface module
The advantages of selecting "Connection via Service" for "Access Type" are as follows:
• An RD81MES96 can be replaced with an RD81MES96N without changing the settings of an MES interface
module and database server.
• A startup time and troubleshooting time can be reduced in a system in which both an RD81MES96 and an
RD81MES96N are included, because a database is accessed by using a same access type.
