OPC UA Server & Client
OPC UA - 최신의 OPC 표준
OPC UA는 최신의 OPC 표준으로
software간의 interoperability면에서 가장 뛰어나다. 이것은 기존의 표준인 OPC "Classic" 표준 (OPC DA, HDA, A&E), RSA 표준으로의 data
encryption 및 x509 Certificate
standard에 기반한 authentication을 하나로 묶은 새로운 OPC 표준이다. 이 표준의 Firewall 친화적인 특징으로 automation 영역과 enterprise 영역간의 시스템 호환성이 뛰어난 보안 기능과 성능을 유지한 채 가능하게 되었다. Kepware OPC Server는 DA Server 이면서 동시에 UA Server가 된다.
Kepware OPC UA Client Driver
하나 또는 다수의 OPC DA Server를 OPC UA Server로 변환하거나, OPC DCOM을 사용하지 않고 OPC UA Server - UA Client를 이용한 OPC Tunnelling을 위해 사용한다.

OPC Tunneler - Leveraging OPC UA
The OPC UA Client Driver
and the free OPC UA Server for KEPServerEX provide an ideal OPC
Tunneling solution. The OPC UA Client Driver provides a communications tunnel
between two or more computers, allowing data to be transferred securely and
reliably. This eliminates reliance on Microsoft COM and DCOM technology, and
provides higher performance and deterministic failure modes.
The OPC
Tunneler uses Client/Server architecture to transfer data over an Intranet,
Internet or WAN. It also creates a secure OPC Tunnel through firewalls and
complements existing OPC DA applications. The OPC Tunnel provides end-users,
integrators and automation suppliers with a favorable solution for remote
connectivity to OPC applications. In comparison to remote OPC Connectivity via DCOM, the
OPC Tunneler boasts security, ease of use and maintainability. Furthermore,
there is no need to expose applications to unauthorized or anonymous users since
OPC UA does not require a VPN connection for
security.
