OPC UA server module
The OPC UA server module realizes embedded OPC UA server which can be installed directly on the MELSEC iQ-R Series base unit. Using this module integrates the OPC UA server directly into the equipment.
Features<sup>Embedded OPC UA server configures a highly reliable system</sup>
- Reliability improvement
- Maintenance cost reduction
- Promotes standardization of connectivity between the IT system and the shop floor with international standard OPC UA communication
- The OPC UA server module improves reliability by eliminating the requirement for a computer-based server, which can be vulnerable to high security risks such as computer viruses. In addition, secure communication with certificate validation and user authentication can prevent theft, tampering, incorrect operation, and unauthorized execution due to unauthorized access by third parties
- Less hardware maintenance is required, reducing overall system cost as industrial control systems have a longer product service life compared to computers
