A-B 1756-L73XT

控制器可分为如下几类：

1. 经典型PLC-5控制器

  有以下几个CPU型号：

处理器名 对应的产品订货号(型号)

PLC-5/10 1785-LT4

PLC-5/12 1785-LT3

PLC-5/15 1785-LT

PLC-5/25 1785-LT2

有以下几种CPU型号：

1785-L11B、1785-L20B、1785-L30B、1785-L40B、1785-L60B、1785-L80B

一般提供DH+或(和)远程输入输出通讯接口(Remote I/O)。

3. 以太网型PLC-5控制器

有以下几种CPU型号：

1785-L20E、1785-L40E、1785-L80E

对以上三种CPU，以太网接口是内置的标准配置。此外还提供DH+或远程输入输出接口

有以下几种CPU型号：

1785-L20C15、1785-L40C15、1785-L46C15、1785-L80C15。

以上四种CPU都内置了控制网(ControlNet)网络通讯功能，此外还提供DH+和远程输入输出通讯连接功能。

5.保护型PLC-5控制器

有以下几种CPU型号：

1785-L26B、1785-L46B、1785-L46C15、1785-L86B。安全型控制器允许用户对“关键的”或“私有的”程序区域、被保护的内存区域、被保护的输入输出等进行访问设置，也可对控制器的操作进行限制。利用编程软件可对用户进行分类管理，使他们具有不同的系统权限。

以上5类控制器除经典型PLC-5控制器外，都带有25针串行通讯口。

Controllers can be divided into the following categories:

1. Classic PLC-5 controller

There are several CPU models available:

The product order number (model) corresponding to the processor name

PLC-5/10 1785-LT4

PLC-5/12 1785-LT3

PLC-5/15 1785-LT

PLC-5/25 1785-LT2

2. Enhanced PLC-5 controller

There are several CPU models available:

1785-L11B, 1785-L20B, 1785-L30B, 1785-L40B, 1785-L60B, 1785-L80B

Generally, DH+or (and) remote input/output communication interfaces (Remote I/O) are provided.

3. Ethernet PLC-5 controller

There are several CPU models available:

1785-L20E, 1785-L40E, 1785-L80E

For the above three types of CPUs, the Ethernet interface is a built-in standard configuration. In addition, it also provides DH+or remote input and output interfaces

4. Control network PLC-5 controller

There are several CPU models available:

1785-L20C15, 1785-L40C15, 1785-L46C15, 1785-L80C15.

All four CPUs above have built-in ControlNet network communication function, and also provide DH+and remote input/output communication connection function.

5. Protective PLC-5 controller

There are several CPU models available:

1785-L26B, 1785-L46B, 1785-L46C15, 1785-L86B. A secure controller allows users to set access to "critical" or "private" program areas, protected memory areas, protected input/output, etc., and can also restrict the operation of the controller. Programming software can be used to classify and manage users, allowing them to have different system permissions.

The above 5 types of controllers, except for the classic PLC-5 controller, all have a 25 pin serial communication port.
