TRICONEX原装PI3381卡件系统DCS工控备件

PI3381-Tricon的双冗余电池组位于机架背板上的正面，在I/O扩展口的旁边。如发生电源故障的情况，这些锂电池能够保存数据和程序，累计保持时间为六个月，所以Tricon建议每五年更换一次电池（锂电池），或者在他们累计使用六个月之后更换。

C.在正常环境中，两个电源模件都是工作的，每一个都向Tricon供电，这时只有PASS和POWER两个指示器灯亮(ON)，任何一个电源模件都可在一定时间内单独给机架.电源模件可以在线更换，视为热备。

数字输出(DO)模件之一出现了LOAD/FUSE错误。-系统中某个地方的模件缺失。-主机架内有一个主处理器或I/O模件故障。

-扩展机架中某个在线I/O模件故障。如果在某一扩展机架内的某I/O模件内有着一支路故障但还能继续正确地运行或者把控制传递给了热备，则主机架报警不会发动。-主处理器探测到有一系统故障。在这个情况下，两个报警触点都有可能被发动二没有相应的模件故障。-机架之间的I/O总线电缆安装不正确（列如支路A的电缆不小心被连到了支路B上）Tricon RS-485扩展总线口的使用

每台Tricon机架底板的左上角装有六个RS-485I/O扩展总线接口，它可以连接到DCS上。用I/O电缆把扩展机架的RS-485口接到其它机架，即在机架内的各I/O模件通过三重的RS-485双向通讯口而连接。每台机架都是多个I/O扩张总线内的一个节点。

The PI3381-Tricon's dual redundant battery pack is located on the front side of the rack backplane, next to the I/O expansion port. In the event of a power failure, these lithium batteries are able to hold data and programs for a cumulative retention time of six months, so Tricon recommends replacing the batteries every five years (lithium batteries), or after they have been used for six months.

C. In a normal environment, both POWER modules are working, each of which supplies power to Tricon. At this time, only the PASS and Power indicators are ON, and any power module can be provided to the rack alone for a certain period of time. The power module can be replaced online, which is considered as hot backup.

A LOAD/FUSE error occurred in one of the Digital Output (DO) modules. - A module is missing somewhere in the system. - One main processor or I/O module in the host subrack is faulty.

- An online I/O module in the extension rack is faulty. If there is a branch fault in an I/O module in an expansion rack but continues to function correctly or transfers control to hot spare, the frame alarm does not activate. - The main processor has detected a system failure. In this case, both alarm contacts may be activated without the corresponding module failure. - I/O bus cables between racks are incorrectly installed (for example, cables from Branch A are accidentally connected to Branch B) Tricon RS-485 expansion bus port

Each Tricon rack has six RS-485I/O expansion bus interfaces in the upper left corner of the chassis, which can be connected to the DCS. The RS-485 port of the expansion frame is connected to the other frame with an I/O cable, that is, each I/O module in the frame is connected through a triple RS-485 bidirectional communication port. Each rack is a node within multiple I/O expansion buses.
