This Extended Product Life Cycle Support Notice is intended to help you plan the maintenance and
evolution of your Mark VIe control system. This notice, as part of a broader Product Life Cycle
Support Policy, protects your investment with extensive replacement parts availability, typically
extending up to 10 years following the end of production date, including planned upgrade paths to
current control technologies.
At inception, Mark VIe controls embraced the principle of extended life cycle through an Ethernet
backbone design with discrete modular building blocks, including controllers, network components,
I/O modules, and extensive software tools. This flexible, modular, upgradeable architecture enables
our 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, parts
life 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The electronics technology for the Mark VIe I/O packs introduced in 2004 is obsolete, and updated
electronics 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 in TMR
systems.
Effective February 1, 2015, GEIP will offer only the updated technology I/O packs as indicated on the
following chart.
