1770-FF工控模块

Allen-Bradley 罗克韦尔部件号为1770-FF 的 CompactLogix 模块化控制器是由 Allen-Bradley 制造的可编程自动化控制器 (PAC)。该控制器通常用于机器控制和中型过程应用。该控制器具有集成的一 (1) 个 RS232 和一 (1) 个以太网通信端口。

RS232 接口的默认配置为 DF1 全双工、19.2 Kbps、无奇偶校验、站地址 0、无握手、BCC 错误检测、自动检测嵌入式响应、8 个数据位和 1 个停止位。可以手动配置此默认配置以建立与设备的初始通信。如果与 RSLinx 一起使用，自动配置可用于自动检测通信设置。同样的 RS232 端口也可以配置为 ASCII 协议接口，以连接到通常用于制造过程的条形码仪器。

以太网通信需要初始配置，可以使用 BOOTP-DHCP 或通过 RS232 接口下载来完成。通过使用 BOOTP-DHCP，需要一根以太网电缆将控制器连接到 BOOTP 主机。软件工具搜索MAC地址，写入用户指定的IP地址。使用 RS232 端口，控制器使用 RSLogix 5000 或 Studio 5000 Logix 设计器定义 IP 地址。

The Allen-Bradley Rockwell CompactLogix Modular controller with part number 1770-FF is a programmable automation controller (PAC) manufactured by Allen-Bradley. The controller is commonly used in machine control and medium process applications. The controller has integrated one (1) RS232 and one (1) Ethernet communication port.

The default configuration of the RS232 interface is DF1 full duplex, 19.2 Kbps, no parity, station address 0, no handshake, BCC error detection, automatic detection of embedded response, 8 data bits, and 1 stop bit. This default configuration can be manually configured to establish initial communication with the device. If used with RSLinx, autoconfiguration can be used to automatically detect communication Settings. The same RS232 port can also be configured as an ASCII protocol interface to connect to barcode instruments commonly used in manufacturing processes.

Ethernet communication requires initial configuration, which can be done using BOOTP-DHCP or downloaded over the RS232 interface. By using BOOTP-DHCP, an Ethernet cable is required to connect the controller to the BOOTP host. The software tool searches for MAC addresses and writes to the IP address specified by the user. Using the RS232 port, the controller uses the RSLogix 5000 or Studio 5000 Logix designer to define the IP address.
