Allen-Bradley 1771-ACN 处理器兼容

Allen-Bradley 1771-ACN 是一个通信模块，用于控制 ControlNet 网络上的 1771 远程 I/O。这个特定的网络允许Allen-Bradley产品与经过认证的第三方产品进行通信。

1771-ACN 与 PLC-5/20C 和 PLC-5/40C 处理器兼容。1771-ACN 与 1771-ACNR 类似，因为它们都具有状态显示、网络访问端口 （NAP）、ControlNet 状态指示灯、放置在模块顶部的模块净地址交换机组件以及通信复位按钮。区别在于 ControlNet 连接器 - 1771-ACN 只有一个，但 1771-ACNR 上有两个可用。

1.0A （5V 直流背板电流）是安装此 ControlNet 适配器模块的要求。安装时，模块需要位于 I/O 机箱最左侧的插槽中。这是因为背板连接器设计为仅接受一种模块。上部连接器上的键控带也需要介于 54 和 56 之间，下部连接器上的键控带也需要介于 16 和 18 之间。插入或取出密钥时，请确保仅用手指进行插入或取出，并且密钥放置正确。安装后，您可以使用分流器将 1771-ACN 连接到 ControlNet 网络。重要的是，只有艾伦-布拉德利水龙头才能用于此以避免出现问题。借助 1771-ACN，用户可以期望高速（离散或非离散）传输时间关键型和非时间关键型数据、通过网络访问端口 （NAP） 进行本地通信网络访问以及诊断消息。

Allen-Bradley 1771-ACN is a communication module for controlling 1771 remote I/O on the ControlNet network. This specific network allows Allen-Bradley products to communicate with certified third-party products.

The 1771-ACN is compatible with PLC-5/20C and PLC-5/40C processors. The 1771-ACN is similar to the 1771-ACNR in that they both feature a status display, Network access port (NAP), ControlNet status indicator, a module Net address switch component placed on top of the module, and a communications reset button. The difference is that there is only one ControlNet connector - 1771-ACN, but two are available on the 1771-ACNR.

1.0A (5V DC backplane current) is a requirement for installing this ControlNet adapter module. The module must be installed in the leftmost slot of the I/O chassis. This is because the backplane connector is designed to accept only one type of module. The keying tape on the upper connector also needs to be between 54 and 56, and the keying tape on the lower connector also needs to be between 16 and 18. When inserting or removing a key, make sure that you only insert or remove it with your fingers and that the key is placed correctly. Once installed, you can connect the 1771-ACN to the ControlNet network using a shunt. It is important that only the Allen-Bradley faucet should be used for this to avoid problems. With the 1771-ACN, users can expect high-speed (discrete or non-discrete) transmission of time-critical and non-time-critical data, local communication network access via a network access port (NAP), and diagnostic messages.
