CE4006P2 m系列串行接口系列

DeltaV控制器自动感应串行接口并提供配置选项。在线帮助使得这个界面很容易配置。经过简单的点击配置练习后，您的集成解决方案就可以启动并运行了。
延长现有设备的使用寿命。增强现有的能力，而不是取代它们。许多工厂已经安装了各种各样的设备。通过串行接口，您可以有效地将DeltaV系统与现有plc或其他串行设备连接起来。这意味着您可以将DeltaV系统提供的最先进的过程控制分层到您已经拥有的设备上。
1:1冗余串行I/O卡。您可以为现有系统添加冗余，前提是从设备支持冗余串行端口。DeltaV冗余I/O使用相同的方法
系列2 I/O卡作为非冗余I/O。这允许您利用在已安装I/O和I/O备件上的投资。不需要额外的配置。
自动感知冗余。DeltaV系统自动检测冗余I/O，这大大简化了向系统添加冗余的任务。冗余卡对在系统工具中被视为一张卡。
自动切换。如果主I/O卡出现故障，系统自动切换到“备用”卡，无需用户干预。操作员在操作员显示器上得到切换的明确通知。

串行接口由一个串行卡和一个终端块组成。卡内有两个串口，支持RS232和RS422/485半双工或RS422/485全双工信号。这些端口可以单独配置，并支持高达115 k波特的数据速率。
该卡具有通用的DeltaV形状因素，允许它插入I/O接口载波中的任何可用插槽。卡上清楚地标明了接口类型。led位于卡的正面，可以一目了然地显示接口的电源、错误和端口状态。
标准Modbus协议包括1992年3月Modbus协议参考手册(PI-MBUS-300 REV D)中定义的串行接口、Modbus RTU和ASCII通信协议。每个串行接口端口可以配置为主设备或从设备。

The DeltaV controller auto-senses the Serial Interface and presents the configuration options. Online help makes this interface a snap to configure. After a simple point-and-click configuration exercise, your integrated solution is up and running.
Extends the life of existing equipment. Enhance existing capabilities—don’t replace them. Many plants have a variety of devices already installed. With the Serial Interface you are able to effectively interface a DeltaV system with existing PLCs or other serial devices. This means that you can layer the state-ofthe-art process control offered by a DeltaV system on to the devices you already have in place.
1:1 Redundancy for Serial I/O cards. You can add redundancy to an existing system, providing the slave device supports redundant serial ports. DeltaV redundant I/O uses the same
Series 2 I/O cards as non-redundant I/O. This allows you to leverage your investment in installed I/O and in I/O spares. No additional configuration is required.
Autosense of redundancy. The DeltaV system autosenses redundant I/O, which greatly simplifies the task of adding redundancy to the system. The redundant pair of cards is treated as one card in the system tools.
Automatic Switchover. Should a primary I/O card fail, the system automatically switches to the “standby” card without user intervention. The operator is given clear notification of a switchover at the operator display.

The Serial Interface consists of a serial card and a terminal block. The card contains two serial communications ports that support RS232 and RS422/485 half duplex, or RS422/485 full duplex signals. These ports are individually configurable and support data rates up to 115 KBaud.
The card has the common DeltaV form factor, allowing it to be plugged into any available slot in the I/O interface carrier. The card is clearly labeled with the interface type. LEDs, located on the front of the card, show the power, error, and port status of the interface at a glance.
The standard Modbus protocol includes the Serial Interface, the Modbus RTU, and ASCII communications protocol as defined in the Modicon Modbus Protocol Reference Manual dated March 1992 (PI-MBUS-300 REV D). Each Serial Interface port may be configured as either a master or slave device.
