You can use Location Intelligence software to exploit the full potential of locating systems in your operations. Real-time analyses support you in optimizing workflows, transport routes and the flow of goods. Thanks to transparency, you can identify and eliminate bottlenecks because you know at all times where the mobile objects are in your production and logistics process.

Use opportunities to optimize production and logistics

Production and logistics processes often come to a standstill because there is simply not enough transparency. Where is product XY in the production process and in what condition is it? Where are the materials you need right now? Why are there always production delays?

Answering these enables you to systematically increase your production throughput, since you can eliminate anomalies such as bottlenecks. This also lowers your costs, for example by reducing the time you spend searching for products and materials.

Bring intelligence to your factory - based on location data

Location Intelligence is the smart way to significantly increase visibility into the operations of your factory. If deviations or problems occur in strictly timed production or logistics processes, you can use Location Intelligence to immediately determine where they occurred. This enables you to find the cause and eliminate it permanently.

Get an overview of material flow and order information

The web-based Location Intelligence software processes data and events from locating systems and can integrate them with your ERP or MES systems. Locating systems such as SIMATIC RTLS use fixed gateways in your nt to detect signals from transponders attached to mobile objects such as material boxes, tools or even automated guided vehicles (AGVs). Transponder movement data is recorded in real time and transmitted from the locating system to Location Intelligence for visualization and analysis. This way, you always have an up-to-date overview of the processes in your nt: a digital twin of your performance.

6ES7 331-7KF02 0AB0（以下简称A）和6ES7 331-1KF02 0AB0（以下简称B），下面就对它们的技术指标做一个比较：

　　1. 模拟量输入模块A和B都是8个模拟量的输入点数，其中模块A允许有4个点作为电阻测量的模拟量输入点数，模块B允许有8个点作为电阻测量的模拟量输入点数。它们选择的前连接器不同，模块A的前连接器为20针，而模块B的前连接器为40针；

　　2. 模拟量输入模块A和B的输入范围略有不同，模块A允许1~5V，-2.5V~2.5V，-250mV~250mV，-500mV~500mV，-80mV~80mV的电压测量范围；而模块B允许0~10V，-50mV~50mV的电压测量范围；对于电流的测量范围，模块A比模块B多了-10mA~10mA和-3.2mA~3.2mA两个范围；

　　3. 模拟量输入模块A和B的输入范围类型不同，模块A可以实现热电偶的输入信号，模块B没有此功能；对于热电阻类型的输入信号，模块A能实现并能进行温度补偿，而模块B没有温度补偿功能；

　　4. 模拟量输入模块A和B的测量精度不同，模块A在单极性情况下，测量精度能达到15位，在双极性的情况下为9，12，14位；模块B的测量精度为13位；

　　5. 模拟量输入模块A和B的中断，诊断功能不同。模块A可对通道0和通道2设置参数，实现诊断中断，对于极限值也可以设置参数；而模块B不具备中断和诊断中断功能

硬件及络组态 本文以采1个315-2PN/DP，1个S7-200 ART PLC为例，介绍它们之间S7通信。 
在STEP7中创建一个新项目，项目名称为S7-300-ART。1个S7-300，在硬件组态中CPU 315-2 PN/DP。如图4所示。
