The controller assembly's three processor modules store and
execute application programs, scan and update the I/O modules,
process communications, and detect system faults. Each of the
processor modules executes the application programs
independently, but in lock-step synchronization with the other two.
And each processor module independently communicates in lock-
step synchronization with the I/O assembly over its own dedicated
I/O Safetybus link.
Features
• Triple modular redundant, fault tolerant (3-2-0) operation.
• Two-out-three hardware voting of all internal operations.
• Automatic fault handling without nuisance alarming.
• Time-stamped fault historian.
•
Hot replacement with pushbutton education of new module
(no need to re-load programs).
• Battery-backed program storage for power outage protection.
• Structured function block programming.
• Multiple program execution.
• Front panel indicators on each module show processor,
communications, I/O, program, battery, memory lock, and
power status.
• TÜV certified for safety, Risk Class 5.
The processor modules use a two-out-of-three voting scheme to
detect faults in the system. The Regent identifies, isolates, and
records transient and permanent faults as they occur. All faults are
recorded in the system's fault history. Permanent faults are also
