SIMATIC WinCC OPC Server + Upd1

SIMATIC WinCC OPC Server + Upd1 is an OPC server component designed to enable standardized data exchange between a WinCC HMI/SCADA system and third-party software. It exposes WinCC process tags—such as real-time values, setpoints, and status information—to OPC-compliant clients for monitoring, control, and data integration. The “+ Upd1” designation typically indicates a maintenance update that includes bug fixes, stability improvements, and possibly security enhancements for the corresponding release.

Key capabilities

• Provides a common, standards-based interface for interoperating with MES, historians, analytics platforms, custom applications, and other SCADA/HMI systems.
• Supports real-time data access (OPC DA) with tag browsing, read/write operations, and subscription-based updates; some editions may also support alarms/events depending on configuration.
• Scales from single-station setups to distributed architectures, reflecting the underlying WinCC project structure.
• Offers configurable access rights and security settings aligned with Windows user accounts and DCOM policies.

Typical uses

• Bridging PLC and SCADA data to enterprise systems without custom drivers.
• Collecting plant data for reporting, archiving, and OEE/quality dashboards.
• Enabling supervisory control from third-party HMIs or engineering tools.

Requirements and notes

• Requires a compatible, installed, and licensed version of WinCC; licensing terms vary by edition and features.
• Network and security configuration (including Windows firewall and DCOM settings) must be aligned with OPC best practices; recent Windows DCOM hardening updates may require additional configuration.
• The exact contents of “Upd1” depend on the specific build; consult the release notes corresponding to your version.
• Developer is unspecified; refer to your distribution source for vendor and support details.

If you provide the exact version/build, I can tailor the description with more precise protocol support, system requirements, and update contents.
