The online import of symbols for TIA Portal V19 is also possible with the updated version. ACCON OPC UA Server has been specially developed by DELTA LOGIC with applications in Siemens S7 and SINUMERIK environments in mind. The server enables secure data transfer between OPC servers and clients and Siemens controllers with outstanding performance.

OPC UA (for Open Platform Communications Unified Architecture) is becoming increasingly established as the standard interface in automated Industry 4.0 processes. ACCON OPC UA Server supports the current OPC UA V 1.04 specification and symbolic access, making it one of the few OPC Foundation-certified servers of its kind in the world.

The latest Siemens software is supported

In addition to support for TIA Portal projects of version V19, the latest update of the ACCON OPC UA Server to version 1.4.0.0 offers support for Siemens S7-1200 controllers with firmware 4.6.1 and S7-1500 CPUs with firmware 3.1.2.

Since version 1.3 of the ACCON OPC UA Server, it is also possible to use virtual devices. This allows users to use virtual variables within the OPC UA Server that are not assigned to a specific hardware device, for example. This allows changes in OPC communication to be tested extensively in a secure environment without touching the production system. If the test is successful and runs as desired, communication with the "real" controller can be resumed.

ACCON OPC UA Server also offers the option of communicating with SINUMERIK ONE and Create MyVirtual Machine. The following features are available for machine tool controllers:

• Support for SINUMERIK ONE, Create MyVirtual Machine, SINUMERIK 840D solutionline, SINUMERIK 840D powerline and 810D powerline
• Convenient access to over 4,000 NC variables and user data (GUD) as well as to SINUMERIK PLC data
• No changes to the CNC software and no Siemens license required
• Determining the utilization and availability of CNC machines
• Monitoring and recording of machine data such as operating mode, torques, power consumption, axis positions
• as well as many more functions

Like all DELTA LOGIC products, the ACCON OPC UA Server impresses with its high performance, great user-friendliness and excellent customer support. DELTA LOGIC offers a maintenance contract for the product, consisting of a software update service (SUS) and premium support: users receive all ACCON OPC UA Server updates by e-mail for the duration of the contract. This ensures that they are always up to date, even with firmware changes or new CPU types. DELTA LOGIC recommends that users of an OPC DA server (regardless of the manufacturer) switch to OPC UA – especially with a view to greater data security.
