Any component that would bring down your critical power system if it failed is called a single point of failure. To avoid blackouts, you need to eliminate all of these single points of failure by consistently ensuring redundancy for these components throughout the control architecture. By doing so, you keep your system online and can achieve tier level compliance.

The multi-master architecture of DEIF DCSes ensures that there is always a command unit able to control the PMS. You can also install hot standby controllers on all positions. Achieving tier-compliant redundancy is not just about the controllers; consider adding extra generator starter systems and a redundant UPS, use two physically separate communication lines, consider the network topology (for example using a ring bus), and remember that breakers and other mechanical equipment can also fail.

You can configure the AGC-4?Mk?II controller for N+X redundancy. By freely selecting how many extra running generators (spinning reserve) you need in the system, you can quickly configure for compliance with even the strictest requirements.

If your entire PMS fails, DEIF controllers can be set up to run in switchboard mode using analogue load sharing that offers stable load sharing and lets you manually start and synchronise generators and prioritise your load groups.
