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
(2)
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.
