ACCON OPC UA Server

OPC UA is the standard in Industry 4.0 and IIoT

Many products rely on the independent interface for easy data exchange between a wide variety of systems without special adaptations. For fast, secure and reliable communication, independent of manufacturer and platform, you need a high-performance OPC UA server in addition to the client interfaces. For Siemens S7 PLCs and Sinumerik controllers, the ACCON OPC UA Server is probably the best performing UA server on the market. Your application doesn't support UA, but DA? Take a look at the S7/S5-OPC-Server for OPC UA.

ACCON OPC UA Server supports Siemens S7 PLCs and SINUMERIK controllers

The ACCON OPC UA Server from DELTA LOGIC was developed especially for the requirements of the Siemens S7 and SINUMERIK controller environment. With it you get highest speed in data transfer both between OPC server and UA client and in transferring your data from an S7 PLC or SINUMERIK controller to the server. The ACCON OPC UA Server offers the perfect solution for your demanding requirements.

Connection via OPC UA:
Read and write data on Siemens PLCs

Connect to your Siemens S7 PLC via OPC UA and read and write data to up to 255 controllers simultaneously. Supported controller types are Siemens S7-300, S7-400, S7-1200, S7-1500, SINUMERIK ONE, Create MyVirtual Machine, SINUMERIK 810D, 840D, as well as S7-compatible PLCs. The Note IDs are compatible to Siemens SOFTNET. No changes in the PLC project are necessary. The ACCON OPC UA Server also offers the possibility for Secure PG/PC and HMI communication (Secure Communication).

Safe testing thanks to virtual devices

Starting with version 1.3 the ACCON OPC UA Server supports client-client communication without requiring a hardware controller via so-called virtual devices. These enable the use of virtual variables within the OPC Server. Furthermore, an existing controller can be virtualized via the Virtual Device Mode. This allows you to perform tests without access to the production system. After switching off the virtual device mode of the controller the hardware device is accessed normally again.

Access to optimized data blocks with OPC Foundation certified OPC UA Server

Play it safe and rely on a software solution certified by the OPC Foundation. Only very few OPC UA servers that support access to optimized data blocks are certified. The ACCON OPC UA Server is one of them and complies with the standard 2017 UA server profile, as well as the OPC Foundation specification version 1.04.

Top performance for data access to S7 and SINUMERIK controllers

Rely on probably the most performant OPC UA server on the market when it comes to data access to your S7 and Sinumerik controllers. In our tests, the ACCON OPC UA Server was the fastest in normal data access compared to our market competitors. Our goal: Provide the fastest OPC UA server on the market. Do you have a scenario where our server is slower than a market competitor? Please contact us. We will analyze your scenario and incorporate the corresponding optimizations into our product.

Multi-project capable symbol import from TIA Portal

The ACCON OPC UA Server supports optimized data blocks as well as online symbol import from S7-1200 and S7-1500 controllers. If you have the right password, even from password protected PLCs*. It is possible to import symbols from Siemens TIA Portal and Simatic Manager projects.
You have several TIA Portal projects? This is also supported by the ACCON OPC UA Server. It is multi-project capable: You can use variables from several TIA Portal projects and Simatic Manager projects in the same Address Space. Even changing the Address Space during operation is possible without a server restart. The variables of your Address Space can be configured via remote configuration over the network.

*Protection level "No access" will be supported in one of the next versions.

SINUMERIK controllers of various models supported

Especially for users of SINUMERIK controls, the current version offers many advantages through the connection:

• Support for SINUMERIK ONE, Create MyVirtual Machine, SINUMERIK 840D pl. 840D sl and 810D pl including comfortable browsing of NC and GUD variables
• Address SINUMERIK controlled machines via OPC UA
• Determine utilization and availability of CNC machines
• Monitoring and recording of machine data such as operating mode, torques, power consumption, axis positions
• Display of the running NC program, number of generated parts and access level
• Access to tool data: Magazine, tool compensation data, tool monitoring data
• Readout of R-parameters, override, number of pending alarms
• Information for preventive maintenance
• Data source for monitoring (dashboard) of the machine e.g. machine status, program status, cycle time, number of pieces, operating hours, OEE

SINUMERIK users also profit from the following highlights:

• Access to over 4000 NC variables
• Access to user data (GUD)
• Comfortable browsing of variables and GUDs
• Access to SINUMERIK PLC data
• No change to the CNC software necessary
• No Siemens license required

Full support of OPC security levels and individual security settings

Different security mechanisms on various levels make your application even more secure. Thus, the ACCON OPC UA Server supports all OPC UA security levels. Depending on the application, you can choose and set them. For user authentication you can choose between access via user name and password or alternatively with a certificate.
In case of a server failure the service restarts automatically. If you wish, you will be notified of this by e-mail. If your certificate should ever expire, you can also be informed about this in good time.

High compatibility from S7-300 to SINUMERIK and TIA Portal

With the ACCON OPC UA Server you can use not only the latest controllers with TIA Portal and online symbol import, but also older controllers, such as the S7-300, as a retrofit.

ACCON OPC UA Server: quickly installed and easy to use

The installation is done within a few minutes. The user interface is clearly arranged and intuitively designed. The ACCON OPC UA Server promises you even more fun at work.
