1734-AENTR 双以太网 POINT I/O 通信模块

【产品详情】

Allen-Bradley 1734-AENTR 是一款双以太网 POINT I/O 通信模块，用于将 POINT I/O 机架连接到以太网 I/P 网络中的中央控制器。该适配器能够在环形、星形和树形拓扑中实现，并由外部 24VDC 电源供电。

1734-AENTR 支持 TCP/UDP/IP 协议，并使用 5 类或 6 类电缆建立物理连接。该适配器支持 10/100 Mbit 传输速度，具有自动协商功能。

IP地址可以通过指轮开关或使用BOOT-P DHCP实用程序进行分配。在大多数应用中，此模块配置了静态 IP 地址。使用静态 IP 地址时，即使设备断电，IP 地址也不会更改。或者，该模块可以配置有动态IP地址。使用动态地址类型时，每次模块重新上电时，IP 地址都会更改。此模式适用于具有非常特定要求的应用程序，因为它可能会由于 IP 地址的突然更改而导致通信错误。

该模块安装在 POINT I/O 系统的最左侧，也是与网络和主控制器建立连接的唯一模块。它通过网络将 I/O 数据从本地 I/O 背板传输到控制器。此外，此 POINT I/O 适配器支持与不同的扫描仪模块同时通信。

Allen-Bradley 1734-AENTR I/O 是一款 2 端口以太网适配器，以 10 至 100 Mbits/s 的速率提供以太网/IP 网络连接，半双工或全双工。它带有 2 个用于直通的 5 类 RJ-45 连接器端口，用于支持环形或菊花链/线性网络，以及现有的树形和星形网络拓扑。这些以太网端口配置为嵌入式交换机。该适配器是用于 POINT I/O 模块的 1734 系列 2 端口通信适配器的一部分。它使用封装在标准 TCP/UDP/IP 协议中的消息。5 类双绞线电缆用于接口。不需要网络调度和路由表。此外，1734-AENTR 能够同时支持来自多个控制器的连接。1734-AENTR 适配器垂直安装在 DIN 导轨上。它附带用于设置网络地址的笔式推式指轮开关。设置网络 Internet 协议地址的其他方法包括从非易失性存储器中检索 IP 地址和使用 DHCP 服务器（将模块设置为启用 DHCP）。为避免未经授权的控制或失去控制，请为 I/O 适配器分配一个固定的 IP 地址。如果使用 DHCP 实用程序，请确保使用与适配器相同的 IP 地址配置它。

【英文介绍】

The Allen-Bradley 1734-AENTR is a dual Ethernet POINT I/O communication module for connecting a POINT I/O rack to a central controller in an Ethernet I/P network. The adapter can be implemented in ring, star and tree topologies and is powered by an external 24VDC power supply.

1734-AENTR supports TCP/UDP/IP protocols and establishes physical connections using Class 5 or Class 6 cables. The adapter supports 10/100 Mbit transfer speeds with auto-negotiation.

IP addresses can be assigned by finger wheel switch or using the BOOT-P DHCP utility. In most applications, this module is configured with a static IP address. When using a static IP address, the IP address does not change even if the device is powered off. Alternatively, the module can be configured with a dynamic IP address. When the dynamic address type is used, the IP address changes each time the module is powered on again. This pattern is suitable for applications with very specific requirements, as it can cause communication errors due to sudden changes in IP addresses.

This module is installed on the far left side of the POINT I/O system and is the only module that connects to the network and the host controller. It transfers I/O data over the network from the local I/O backplane to the controller. In addition, this POINT I/O adapter supports simultaneous communication with different scanner modules.

The Allen-Bradley 1734-AENTR I/O is a 2-port Ethernet adapter that provides Ethernet /IP network connectivity at rates of 10 to 100 Mbits/s, half duplex or full duplex. It comes with 2 Category 5 RJ-45 connector ports for pass-through to support ring or Daisy chain/linear networks, as well as existing tree and star network topologies. These Ethernet ports are configured as embedded switches. This adapter is part of the 1734 Series 2-port communication adapter for POINT I/O modules. It uses messages encapsulated in standard TCP/UDP/IP protocols. Category 5 twisted pair cables are used for interfaces. Network scheduling and routing tables are not required. In addition, the 1734-AENTR is capable of supporting connections from multiple controllers simultaneously. The 1734-AENTR adapter is mounted vertically on the DIN rail. It comes with a pen push-finger wheel switch for setting network addresses. Other ways to set up the Internet protocol address for the network include retrieving the IP address from non-volatile memory and using a DHCP server (setting the module to enable DHCP). To avoid unauthorized control or loss of control, assign a fixed IP address to the I/O adapter. If you use the DHCP utility, make sure to configure it with the same IP address as the adapter.
