一開始，Mark VIe controls采用了通過以太網(wǎng)延長生命周期的原則采用離散模塊化構建塊的主干設計，包括控制器、網(wǎng)絡組件、，
I/O模塊和廣泛的軟件工具。這種靈活、模塊化、可升級的體系結構我們的客戶需要通過升級或更換組件來維護進的控制系統(tǒng)
根據(jù)需要。這種設計允許進行增量技術升級、過時保護和零部件更換生命周期規(guī)劃和的系統(tǒng)升級，無需更換整個系統(tǒng)控制系統(tǒng)。
2004年推出的Mark VIe I/O包的電子技術已經(jīng)過時，并且已經(jīng)更新電子技術于2010年推出。更新的Mark VIe I/O包包括向后兼容，并且可以與舊技術（包括TMR）混合和匹配
系統(tǒng)。2015年2月，通用電氣宣布組IO模塊將過渡到較新的版本技術模塊列表附在附錄A中，您可以參考GE的生命周期通知

￥為了確保使用此更新的I/O技術提供方便的服務，您可能需要在下次停機期間進行一些準備工作。準備工作的級別取決于網(wǎng)站硬件和軟件的修訂級別。要安裝這些替換IO
模塊，您將需要確保使用規(guī)定的ControlST版本或更高版本運行。

At inception, Mark VIe controls embraced the principle of extended life cycle through an Ethernetbackbone design with discrete modular building blocks, including controllers, network components,
I/O modules, and extensive software tools. This flexible, modular, upgradable architecture enablesour customers to maintain a state-of-the-art control system by upgrading or replacing components
as needed. This design allows for incremental technology upgrades, obsolescence protection, partslife cycle planning and comprehensive system upgrades, without the need to replace the entire
control system.
The electronics technology for the Mark VIe I/O packs introduced in 2004 is obsolete, and updatedelectronics technology was introduced in 2010. The updated Mark VIe I/O packs are
backward-compatible, and can be mixed and matched with the older technology including TMRsystems.
In February 2015, GE announced the first group of IO modules to transition to the newer
technology. The list of modules is attached in Appendix A and you can refer to GE’s life cycle notice
GEZ-S2026 for more information.
Today, GE is announcing the additional IO packs below he transitioned to the upgraded
technology: Obsolete Catalog

? On a TMR card, all 3 safety Packs must be upgraded to the same version at the same time. Mixing S1A and S1B packs are
not supported on the same Terminal Board; however, you can he S1A and S1B mixed within a Mark VIe System on different
terminal boards. Please refer to GEH-6721 Volume II.
￥ To ensure ease of service with this updated I/O technology, some preparation work may be required during your next outage.
The level of preparation depends on the revision level of your site’s hardware and software. To install these replacement IO
modules, you will need to ensure that you are running with the stated minimum ControlST version or version or later.
