一开始，Mark VIe controls采用了通过以太网延长生命周期的原则采用离散模块化构建块的主干设计，包括控制器、网络组件、，
I/O模块和广泛的软件工具。这种灵活、模块化、可升级的体系结构我们的客户需要通过升级或更换组件来维护进的控制系统
根据需要。这种设计允许进行增量技术升级、过时保护和零部件更换生命周期规划和的系统升级，无需更换整个系统控制系统。
2004年推出的Mark VIe I/O包的电子技术已经过时，并且已经更新电子技术于2010年推出。更新的Mark VIe I/O包包括向后兼容，并且可以与旧技术（包括TMR）混合和匹配
系统。2015年2月，通用电气宣布组IO模块将过渡到较新的版本技术模块列表附在附录A中，您可以参考GE的生命周期通知

同一端子板上不支持；但是，您可以在不同的机器上将S1A和S1B混合在Mark VIe系统中终端板。请参考GEH-6721第二卷。
¥为了确保使用此更新的I/O技术提供方便的服务，您可能需要在下次停机期间进行一些准备工作。准备工作的级别取决于网站硬件和软件的修订级别。要安装这些替换IO
模块，您将需要确保使用规定的ControlST版本或更高版本运行。

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The electronics technology for the Mark VIe I/O packs introduced in 2004 is obsolete, and updatedelectronics technology was introduced in 2010.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.
