SLC 500系列是一个不断充实的小型可编程控制器系列。该系列有两种硬件结构：固定式控制器与模块式控制器。固定式将电源、输入与输出以该处理器集中在一个单元。固定式控制器还提供一个2槽的扩展框架以增加其灵活性。模块式控制器使用户在组态系统时具有额外的灵活性，它具有更强的处理能力，以及I／O容量。
除了组态灵活之外，SLC 500可编程控制器之间可以通过内置的DH-485网络进行通讯，以进行编程和监控。产品目录号为1747-L532的SLC5/03__M处理器提供多达960个l／O点，在线编程和一个能在3种运行模式（运行、编程与远程）之间进行选择的钥匙开关。包含在SLC5/03处理器中的还有一个RS-232通道，它支持与终端设备之间的异步串行数据通讯。产品目录号为1747-L541、1747-L542以及1747-L543的SLC5/04__M处理器除了具有与SLC 5/03相同的特性外，还增加了一些功能。

The system allows different types of field buses to be mixed and run simultaneously in the same field controller PS.
Industrial “field control explosion (AC800F) consists of the following components:
Basic unit pm802f
Power supply sa801f/sd802f
o
Ethernet network card ei801f/ei802f/ei803f
o
Fieldbus interface card fi810f/fi820f/fi830f
Various accessories
The main components of the field controller PS are described below.
Basic unit pm802f
The basic unit pm802f is composed of a metal rack and a CPU motherboard. It periodically scans the data from the
The signals of the field bus sensors are processed according to the control application program configured by the user, and then the calculation results are passed
The fieldbus interface card returns the corresponding fieldbus actuator.
Two field controllers can realize controller 1:1 redundancy, and undisturbed switching between master and slave PS. Two on each PS
Ethernet network card, the second network card is used to connect the system network diginets), and the second network cards can be interconnected with each other to form a special
Redundant communication link (diginetr) to ensure information synchronization between master and slave PS. — However, the master PS fails, and the slave PS can quickly and undisturbed connect the replacement worker
Make. All inputs and outputs also support redundant operation.
The data communication between the field process controller PS. operating station 0s and the engineer station es is completed by the system network (diginets), which is inserted
The – Ethernet network card on the PS basic unit provides the interface between PS and diginets. ES. Hardware configuration and PS
The user program is downloaded to the PS CPU through diginets and the first network card. After the field bus interface card is newly installed or replaced, the required group
The status information will be automatically reloaded. The configuration results and real-time process data are stored in RAM, and ram is installed on the Ethernet network card or battery card
The backup battery can maintain the configuration
