7-2. Examples
These are some examples demonstrating the configuration of the interface to
accomplish various tasks.
7-2.1. Example 1
An interface is needed to a controller which communicates using the Modbus
protocol. The controller has analog values in registers HR40001 through HR40009
representing two temperatures and a pressure for each of three units. The sixteen bit
Modbus registers are holding data from twelve bit I/O and so range from 0 to 4095
counts.

7-2. 例子
以下是一些示例，演示了
完成各种任务。
7-2.1. 例1
控制器需要一个使用Modbus进行通信的接口
协议控制器在寄存器HR40001到HR40009中有模拟值
代表三个单元中每个单元的两个温度和一个压力。十六位
Modbus寄存器保存来自12位I/O的数据，因此范围从0到4095
计数。
