对应输出值表，I/O通讯处理器产生若干个子表，每个子表分别对应于系统内的一个输出模件。通过I/O总路线将子表传送至相应的输出模件的对应分电路。例如，主处理器A通过I/O总线A，传送相应的表给每个输出模件的分电路A。输出数据的传送在所有I/O模件的例行扫描上具有优先权。
I/O通讯处理器通过支持广播机制的通讯总线管理着主处理器和通讯模件之间的数据交换。
#3008型主处理器有16M DRAM（无后备电池）和32K  SRAM，用于存放用户编写的控制程序、SOE1数据、I/O数据、诊断、以及通讯缓冲器。外部电源故障时SRAM可完好地保存用户程序和保持性内存接点，时间为至少六个月。
TriBus硬件表决电路周期性对验证内存的有效性。

主处理器模件接受双电源供电，电源母线排列在主机架内。一个电源或电源母线出现故障不会影响系统性能。

在发生外部电源故障时，SRAM由装在主机架的背板上的电池进行保护。Tricon在没有外部电源的情况下，电池能完整地保持程序和保持性变量，至少可保持六个月。Pacific Scientific Honeywell DC Motor EP3640-1436-7-56C
