Introduction
System/solution providers are engaged by their customers to deliver cost effective solutions that have an “open systems” foundation.
They are often challenged to decide whichStandard will provide their customer with the best solution.
Which solution will provide a foundation the customer can build upon for future expansion?
How will total life‐cycle costs be impacted?

LonMark Certified Devices Benefits for Manufacturer
• Standard Profiles reduce software design time
• Low cost SoC available from multiple manufactures
• Peer‐to‐peer network does not require a “Master” device to control network traffic flow. Small systems 3‐4 controllers can be cost effective.

Who cares about standard profiles?
• Controller manufactures/suppliers care about product line having consistency within their own company, as they often supply software solutions as well.
Who Cares About Profiles?
• Integrators typically work with a single vendor at a time. This reduces the concern about having a varied point list for similar devices.
• If they can “integrate” any point between controllers, it typically satisfies their needs.

End User & ISV
• End User and Independent Software Vendors (ISV) do care about a standard device profile.
• Consistency reduces training for end user.
• Provides longer life‐cycle of for system designs
• Enables Enterprise level applications that are multi‐vendor!
