能够远程监视和控制在模拟工业自动化领域中运行的多个设备可以为最终用户带来许多好处。
远程过程控制和监控,显着降低维护成本,最大限度地减少因无需亲自前往设备位置而导致的停机时间,这些主要优势可吸引那些管理连接“智能”设备网络的人员,无论是在工厂/工厂环境中还是
在该领域更广泛传播。
在这个特定的空间中,高速可寻址远程传感器(HART)通信基金会已经成为通过模拟线路发送和接收数据的全球标准。
这些机构或组织是定义协议并为那些利用其专业利基技能和专业知识为市场设计和开发系统和单个组件的企业营造一个有凝聚力,前瞻性思维环境的重要实体。
在整个电子行业中,许多设置以与HART通信基金会类似的方式提供标准开发,支持和围绕特定终端市场需求的整个生态系统演变的焦点。
示例包括便携式设备无线充电领域中的Power Matters Alliance(PMA)和Qi Wireless Power Consortium。
HART协议的关键是使用Bell 202频移键控(FSK)标准将数字数据通信叠加到4至20 mA模拟线路上。
安森美半导体最近成为该基金会的“注册”成员,推出了最新的低功耗CMOS调制解调器IC  -  NCN5193--符合HART的物理层规范,旨在用于工业过程控制的通信。
我们的集成调制解调器旨在支持可靠和安全 - 意味着最大限度地降低了昂贵的通信中断风险以及在危险环境中的安全操作 - 在非常具有挑战性的工业环境中以每秒1200位的速度提供数据。

当然,许多其他HART通信基金会成员也制造符合协议的设备,并满足整个远程工业通信解决方案的特定方面的要求。
与NCN5193等组件配合使用,可以帮助开发可靠,优化的终端产品,这些产品能够完全满足远程监控,控制和诊断需求。

Being able to remotely monitor and control multiple devices operating in the analog industrial automation sector can bring a host of benefits to end-users. Remote process control and monitoring, significantly reduced maintenance costs and minimized downtime associated with not having to physically travel to the equipment location are the major pluses that appeal to those managing a network of connected ‘smart’ devices, either in a plant / factory environment or more widely spread in the field.
In this particular space, the Highway Addressable Remote Transducer (HART) Communication Foundation has become well-established as the global standard for sending and receiving data across analog wires. Such bodies or organizations are a vital entity to define protocols and foster a cohesive, forward thinking environment for those businesses using their specialized niche skills and expertise to design and develop systems and individual components for the market.
Throughout the electronics sector there many set-ups that, in a similar way to The HART Communication Foundation, provide the focal point for standards development, support and the evolution of whole ecosystems around a specific end-market need. Examples include the Power Matters Alliance (PMA) and the Qi Wireless Power Consortium in the portable device wireless charging sector.  
The crux of the HART protocol is the use of the Bell 202 Frequency Shift Keying (FSK) standard to superimpose digital data communications on to 4 to 20 mA analog lines. ON Semiconductor recently became a ‘signed-up’ member of the foundation following the launch of its latest low-power, CMOS modem IC - the NCN5193 - that complies with the physical layer specifications of HART and is targeted at communications for industrial process control. Our integrated modem is designed to support reliable and safe – meaning minimized risk of costly communications interrupts and safe operation in hazardous environments - delivery of data at 1200 bit per second in what can be very challenging industrial environments.

Of course, numerous other HART Communication Foundation members also manufacture devices that align with the protocol and meet the requirements of specific aspects of an overall remote industrial communications solution.  In conjunction with components such as the NCN5193, these aid the development of reliable, optimized end products that are able to do exactly what those performing remote monitoring, control and diagnostics need.
