PLC/可编程控制系统 1747-L541

Allen-Bradley 1747-L541是SLC 5/04控制器，具有集成的16 KB用户存储器，设计用于处理多达4096个输入和输出。该控制器属于模块式SLC 500可编程逻辑控制器(PLC)。

1747-L541非常适合在中型应用中使用，因为该控制器能够通过使用CPU机架上的通信适配器和IO机架上的通信扫描仪来实施分布式IO应用。RS232通信端口可针对DF1和DH485点对点拓扑进行配置，而DH+通信支持长距离和多点拓扑。

或者，RS232通信端口也可以与1761-NET-AIC一起使用，以允许串行端口连接到多点网络。对于RS232端口和57.6千波特，节点地址= 1，对于数据高速公路Plus (DH+)，通信端口默认设置为无握手、19.2千波特、CRC错误检查、重复包、检测开和无奇偶校验。

1747-L541控制器需要一个SLC 500机架来安装和连接到电子背板。还需要系统电源通过电子背板给处理器的内部电路供电。

这种控制器是UL上市的美国和加拿大的安全标准，符合CE和C-Tick标志。

1747-L541

The Allen-Bradley 1747-L541 is an SLC 5/04 controller with integrated 16 KB user memory designed to handle up to 4096 inputs and outputs. This controller is part of the modular SLC 500 programmable logic controller (PLC).

The 1747-L541 is ideally suited for use in medium-sized applications because the controller is capable of implementing distributed IO applications through the use of communication adapters on the CPU rack and communication scanners on the IO rack.The RS232 communication port can be configured for DF1 and DH485 point-to-point topologies, while the DH+ communication supports both long-range and multipoint topologies.

Alternatively, the RS232 communications port can be used with the 1761-NET-AIC to allow serial ports to be connected to multipoint networks. For the RS232 port and 57.6 kilobaud, Node Address = 1. For Data Highway Plus (DH+), the communications port default settings are No Handshake, 19.2 kilobaud, CRC Error Check, Duplicate Packet, Detect Open, and No Parity.

The 1747-L541 controller requires an SLC 500 rack to mount and connect to the electronic backplane. It also requires a system power supply to power the processor’s internal circuitry through the electronic backplane.

This controller is UL listed for safety in the U.S. and Canada and is CE and C-Tick marked.
