Virtualization has long been exemplified in the IT sector and has been helping to optimize processes and improve agility for years. In industry and automation technology, it is becoming increasingly important to map processes virtually. We are already implementing complete plants virtually for customers.
Depending on the area of application, there are different ways of proceeding or possibilities for mapping a plant virtually, either in part or in its entirety. We are pleased to advise you in detail in advance.
In this case, the physical hardware is abstracted from the existing operating system and pulled in on a virtualization layer (hypervisor, VMware, vSphere, etc.). This allows different workstations to run in parallel over the same hardware, faking physical realities as actually existing. A virtual machine has its own virtual system components.
In case of this process, it is possible to dynamically allocate resources depending on the requirements. Scaling in width is also possible, so new virtual workstations can be created or added at any time.
Comparison of physical and virtual structure
In a virtual setup, the hypervisor is run directly on the real hardware of the host system. Because direct operation of the virtual machines is not possible in this case, additional thin clients are required. These only need a network connection and establish a remote connection with the virtual machine. Data retention via the thin clients is not possible, but they ensure location-independent and flexible access and can be easily replaced in the unlikely event of a defect. Connections are also possible via a Windows-based device, e.g. via a remote desktop connection or via a suitable VNC client.
To meet the requirements for permitted remote connection protocols of PCS 7, TRIPS relies on thin clients with which VNC and RDP connections can be established via one device. With this setup, up to four screens (up to 4K resolution) can be controlled per workstation, which are also suitable for harsh conditions and operation at 0 °C to -35 °C.
In order to ensure redundancy, the virtual PCS7 system is always delivered with at least two host systems. This redundant design of the PCS7 system distributes the virtual machines to the host systems (at least two servers) so that continuous operation of the system can be guaranteed in the event of a hardware failure.
In terms of data security, we leave nothing to chance. Each server host system is installed in an appropriate 19″ server cabinet, which allows access only to authorized persons and protects all hardware from dust and moisture.
You can backup your data flexibly on an existing storage or alternatively via a storage solution from TRIPS. We recommend using Veeam Backup & Replication to ensure a comprehensive and scheduled backup of all virtual machines (1 to several times per day). You also have retention and long-term archiving of the virtual machines and receive regular email notifications about the current status of the backup.
All from one – integrated, personalized virtualization solutions
We provide you with all the necessary components for commissioning a new plant or expanding and updating an existing plant from a single source.
- Setup virtual PCS7 system with the required server hardware, thin clients (complete Workplace consisting of: Thin client, screen, mouse & keyboard) or flexibly choose which components you want to obtain
- Software licenses
- Switchgear and server cabinets
Your advantages of virtualization over the classic client-server principle
- Reduction of costs
Thin clients save on both cables and computers, as only one network connection to the system is required and the clients switch flexibly between multiple connections to different virtual machines
- Increase safety
You have fewer attack vectors and more security through rights management in the virtual machines
- Improved availability
Always accessible thanks to exchangeable virtual machines on the host system and thin clients at the workstation. In addition, you receive spare parts and support for hardware problems from the server manufacturer
- High flexibility
By using different operating systems and switching on or distributing the virtual machines, you can always adapt your system to the current conditions
