Main Processor Modules
Model 3008 Main Processors (MP) are
available for Tricon v9.6 and later
systems. For detailed specifications,
see the Planning and Installation Guide
for Tricon Systems.
Three MPs must be installed in the
Main Chassis of every Tricon system.
Each MP independently communicates
with its I/O subsystem and executes the
user-written control program.
Sequence of Events (SOE)
and Time Synchronization
During each scan, the MPs inspect
designated discrete variables for state
changes known as events. When an
event occurs, the MPs save the current
variable state and time stamp in the
buffer of an SOE block.If multiple Tricon systems are
connected by means of NCMs, the time
synchronization capability ensures a
consistent time base for effective SOE
time-stamping. See page 72 for more
information.
Diagnostics
Extensive diagnostics validate the
health of each MP, I/O module and
communication channel. Transient
faults are recorded and masked by the
hardware majority-voting circuit.
Persistent faults are diagnosed and the
errant module is hot-replaced.
MP diagnostics perform these tasks:

static RAM
