Main Processor Modules
Model 3008 Main Processors 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 70 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:
• Verify fixed-program memory and static RAM
