3BHB018162R0001信号处理模块,5SHY4045L0001可控硅模块
主处理器模块
3008型主处理器（MP）包括
适用于3BHB018162R0001及更高版本系统。有关详细规范，
对于Tricon系统。
三个MPs必须安装在每个Tricon系统的主机箱。
每个MP独立通信并执行用户编写的控制程序。
事件顺序（SOE）和时间同步
在每次扫描期间，MPs检查状态的指定离散变量
更改称为事件。当事件发生时，MPs保存当前
中的变量状态和时间戳SOE块的缓冲区。如果多个Tricon系统
通过NCMs连接，时间同步功能确保
有效SOE的一致时间基础

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:
• Verify fixed-program memory and
static RAM
