OPC UA Server 2.2 for SINUMERIK 828D and SINUMERIK 840D sl released

  • Entry
  • Associated product(s)
With the software option SINUMERIK Integrate Access MyMachine/OPC UA, the SINUMERIK 828D / 840D sl features an OPC UA server. This makes it possible to access the SINUMERIK 828D or SINUMERIK 840D sl via the network on the basis of a standardized protocol. The new version 2.2 supports the reinstallation to SINUMERIK software version 4.5.

The increasing vertical networking in production requires platform-independent communication.
The reliable manufacturer and platform-independent industrial communication protocol OPC UA is becoming even more popular in the industry sector.

With SINUMERIK Access MyMachine /OPC UA, the SINUMERIK offers an OPC UA server which provides read and write access to the SINUMERIK tags and allows to register for value changes. Further, the OPC UA server provides the event-based provision of SINUMERIK alarms and several methods for simple interaction with the SINUMERIK.

The user management system, which allows read and write rights to be individually assigned and the connection to be encrypted, ensures the protection of your data.

The OPC UA server can be accessed via the company interface (X130) of the relevant controller.
Further, the OPC UA server can also be accessed via the plant network interface (X120) with SINUMERIK 840D sl.
When using a SINUMERIK PCU/IPC in combination with a SINUMERIK 840D sl, the OPC UA server is accessed via the SINUMERIK PCU/IPC interfaces instead of the controller interfaces.

The existing OPC UA Server Version 2.1 already provides the following functions:
  • Reading and writing of variables (Read / Write)
  • Registration for value change (subscription)
  • Event-based provision of SINUMERIK alarms
  • Simple overview about the NC programs through support of the OPC UA file and folder objects
  • Upload/download of part programs between an OPC UA client and the controller
    Accessible folders: Part programs, subprograms and workpieces.
  • Further methods for the creation and deletion of tools and cutting edges, and the selection of the next part program
  • Easy possibility to activate / deactivate end points (interfaces)
  • The diagnostic dialog allows to obtain a quick overview about the status of the server and the nodes connected
  • Provision of server diagnostics information via OPC UA
  • Support for all authentication methods described in the standard
    (anonymous, user name + password, certificate-based authentication)
  • The certification management feature in SINUMERIK Operate facilitates the commissioning and management of certificates
  • Support for 128-bit and 256-bit encryption
  • Can be reinstalled in SINUMERIK software versions 4.7 / 4.8 as of 4.7 SP2

Further, the new OPC UA Server Version 2.2 provides the following benefits:

  • Can be reinstalled in SINUMERIK software version 4.5  as of 4.5 SP4
  • Enhanced access protection by DB, selective read and write access to PLC data
  • Support of external drives (only in combination with SINUMERIK software version V4.7 or higher)

Commissioning takes just a few minutes via a configuration dialog in SINUMERIK Operate. More detailed information is provided in the operating instructions under 109481648.

OPC UA Server 2.1 is included in SINUMERIK software version 4.8 SP3 or higher, but can also be subsequently installed in other versions of the 4.7 and 4.8 software lines.  For the time being, OPC UA Server 2.2 is only available as an update. If you wish to obtain the update file,  please contact your regional Siemens representative.

This means all the advantages of the new server version are available for existing machines, too, without the need to upgrade the entire SINUMERIK software version.
