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
