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。
tandard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.

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 hav
