SIMATIC OPC UA S7-1500

Manufacturer independent communication for Industry 4.0

OPC Unified Architecture

The vendor- and platform-independent OPC Unified Architecture (UA) is the communication standard for Industry 4.0 and is the standard mechanism for accessing S7-1500 data from non-Siemens devices.

OPC UA can be used in all Ethernet networks thanks to the underlying TCP/IP communication. In particular, OPC UA and PROFINET are fully compatible, thus permitting parallel operation. Therefore other field devices in addition to the CPU can also be linked (to the IT levels, for example) using OPC UA

Benefits

  • Simple, standardized, and secure connectivity across all levels

  • Platform and manufacturer independent

  • The combination of OPC UA & PROFINET satisfies all industry requirements with regard to digitalization

  • Limitless communication across all levels with no gateways or additional hardware

  • Use of only one network from automation to the IT level

  • Unrestricted parallel operation with PROFINET and TCP/IP

  • Simple expansion of the existing PN network through the OPC UA devices

  • Maximum scalability


Functions

  • OPC UA server directly in the S7-1500

  • OPC UA data access, read/write, subscription for changes in value

  • Mapping of all enabled instances and types from the user program

  • Access to structures and arrays as complete objects

  • Security up to SH 256 certificates

  • XML export for offline configuration of OPC UA clients


Licensing

There are three variants of runtime licenses depending on the chosen target system.
The single runtime license download contains certificate of license OPC UA Server (Data Access), class A, running on the target system incl. F and T derivates from firmware V2.
