Circular Redundancy©

Secure, elegant and unique

Circular Redundancy is the logical connection of seamless redundancy and multiple project administration. An ideal solution to save costs and increase safety at the same time.

Circular Redundancy requires one project standby server in addition to each project server. zenon takes full advantage of the possible resources with the help of the possibilities of multiple project administration and horizontal transparency: the neighboring project server simultaneously serves as a standby server and vice-versa.

This way, with less hardware, security is increased, the breakdown risk is reduced, and less maintenance work is needed.

An example with three projects:

On PC 1 project A is running as a server project; project B as a standby project.

On PC 2 project B is running as a server project; project C as a standby project.

On PC 3 project C is running as a server project; project A as a standby project. The circle is closed!

In the above case three redundant projects are realized when normally this would have required 6 PCs. Usually you would need 6 PCs for this solution. Of course Circular Redundancy is not limited to three projects but can connect as many projects as desired in a circle. The fact that the PCs can at the same time be clients of other projects, allows the easy realization of a low-cost, failure-safe, highly available production line.
