For facilities managers of large buildings and campuses, security and access control are huge challenges. Authorized persons come and go so privileges must be granted and revoked; different employees, students and visitors may all have different levels of privilege/access; the access cards themselves must be authenticated; and the list goes on. This is in the face of ever-escalating security threats – both cyber and physical. But even before the facilities managers get to the point of having to handle these logistical challenges, they must choose an access control system.

I recently spoke with Rick Ashmus, CEO of a company called Abba Logic. Based in Wisconsin, USA, Abba Logic has been creating access control and programmable logic control (PLC) systems since 1999. Today the company has hundreds of systems all over the world operating 24 hours a day. Their products are primarily used in buildings that require high levels of secure access, such as correctional facilities, police stations, courthouses, hospitals, schools and government buildings, but the technology is broadly applicable into every environment needing access control.

“选择访问控制系统时，重要的是要明白它不仅仅是关于产品本身的成本，”Ashmus说。“安装，集成和接线也有显着成本。When you have a campus with multiple buildings and hundreds of intercoms and doors – each with their own card readers – and when you consider that you must network everything together and be controlled by one overarching security system, you’re looking at resource intensive integration and programming efforts.”

最大挑战之一是需要可扩展的IP连接 - 具有潜在数千台设备的多个建筑物之间。FT技术简化了设计，因为一个IP地址可以具有数百个较小的控制器，使用该地址具有自己的子地址。这些子控制器中的每一个都可以监视20或30个I / O点并彼此通信。

Adesto’s embedded IoT solutions solve this challenge for Abba Logic, simplifying installation and improving performance with:

• 一种高度分布式的事件驱动的网络架构
• 通过首选IP标准对等功能和通信
• 极性不敏感FT接线，可以创建易于易于误差，更容易耐受性并具有高噪声免疫力的复杂网络
• No need for extensive home run wiring which is needed for some other systems
• No need for polling for status, which adds overhead and can result in latency
• FT Communications没有单点失败

The Abba Logic solutions are based on Adesto’s embedded IoT technology and provide IP connectivity between buildings and areas of control, with the ability to access a central computer from virtually anywhere and distribute user roles and access.

The central processor used in all of Abba Logic’s access controllers is theFT 6050智能收发器SOC。FT 6050非常适合使用，Ashmus说，由于处理设备到设备通信所需的Lon IP代码已经写入 - 并写得很好。“它只是有效，”他说。“这真的很重要。通过在银行中的那段代码，所以要说，我需要做的就是开发应用程序代码。Adesto提供了一个开发套件，其中一半的工作已经完成了。整体发展成本较低。“

The FT 6050 uniquely supports LON, LON/IP, BACnet/IP and BACnet MS/TP protocol stacks. It lets the LON and BACnet industrial protocols – which are widely used in buildings – communicate simultaneously over Free Topology (FT). FT is an industry-wide, broadly adopted connectivity standard that can operate over any unshielded twisted-pair wiring or Cat 5 cabling.

“当集成商来安装系统时，FT是一个好处，因为布线说，布线如此简单得多，所以。“用FT，您有一个点对点接线的分布式概念。布线的极性不敏感性也很大，因为你永远不能得到逆转的电线。“

在同一网络上具有本机BACnet和LON通信，可以将建立自动化系统的方式进行架构。解决方案提供商可以从不同供应商混合设备和应用程序。雷竞技安卓下载这导致为广泛的IOT使用情况创建分散的对等通信 - 包括安全性和访问控制系统。使用FT 6050，可以将现有的BACnet或LON系统连接到逐步迁移控制器，而不是更改整个系统。

When Abba Logic began using the FT 6050, the company was able to reduce the number of processors per control panel from four in its previous product to two. This increased the speed of operations while achieving a 50 percent reduction in the overall cost. Because the FT 6050 has advanced distributed processing capabilities, it also enables more access points to be controlled on a single cable run.

Abba Logic’s control panels work with the company’s Managed Automation Security Controls (MASC) HMI software to provide integrated security and building control solutions. And while the company’s products are sophisticated, its GUI is highly intuitive to make it easier to integrate and manage the systems. The system can integrate access control, PLC, camera control, and intercom control into one user friendly software package.

“The differentiation of the Abba Logic solution is our amazing, intuitive GUI with touch screen capability, and a graphical building control map. This just makes it work for customers behind the scenes.”

Adesto’s embedded IoT solutions enable Abba Logic to focus on what it does best without having to worry about installation and integration. The next time you swipe your entry card on your building’s card reader, take a moment to think about all of the thought, intensive design, installation and integration work that has gone into making it possible. And if that system is based on Adesto’s technology, stop by to congratulate your facility manager on making a smart selection.
