每个FlexLogix系统中有一个多用途的可编程序控制器。用户将I/O点分布到与传感器或执行器距离更近的位置。并且，可以将多个FlexLogix控制器连到同一网络用作分布式处理。
FlexLogix控制器具有Logix控制引擎，因此该控制器支持Logix指令集、任务模型和数据模型。使用RSLogix5000编程软件对FlexLogix控制器和其它Logix控制器进行编程和I/O组态的步骤是通用的。1794 I/O产品提供的模块化组件包括一系列数字量和模拟量I/O(包含智能I/O)。一个简单的FlexLogix系统可以由一个控制器和最多8个I/O模块组成

ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations

4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be
