Introduction of Features
Overview
The OPC-UA server function enables OPC-UA clients of a host system (SCADA,
1
MES,
2
etc.) to access the I/O channels, math channels (/MT), and communication channels (/MC)
of a GX/GP/GM for data reading and writing through Ethernet.
In addition, the function also includes data change notification and the corresponding
message and filtering (subscription) functions.
The maximum number of OPC-UA clients that can connect to a GX/GP/GM is three.

Device information
1 SCADA (Supervisory Control And Data Acquisition) is a type of industrial control
system. It monitors and controls industrial, infrastructural, or facility processes using
computers.
2 MES (Manufacturing Execution System) is a system that is linked to production sites
to grasp and manage production process status, provide instructions and aid to
operators, and the like.
Features
• Incorporation of the OPC-UA server function allows easy connection to OPC-UA clients.
• Various production process data from production sites can be monitored from a host
system such as SCADA and MES.
• Monitoring data changes and sending event notifications are possible through OPC-UA
communication (subscription).
• Acquisition data is saved to the GX/GP/GM’s internal memory and then to an SD card. As
such, even if there is a network communication problem, data is backed up.
Benefits
• Because connecting to a host system is easy, the cost of constructing a system for
acquiring various process data in production sites can be reduced.
• Acquisition of various process data of production sites on a host system enables
production control including monitoring of production processes and feeding back data to
production processes.
• Even if a network communication problem occurs, data stored in the internal memory or
SD card can be referred to and used for production control.
