VE4006P2  m系列串行接口系列

The Serial Interface provides a connection between the DeltaV™ system and devices that support a serial protocol, such as Modbus or Allen Bradley’s Data Highway Plus.
The Serial Interface is supplied with Modbus software drivers pre-loaded. Plug your Serial Interface into any available slot in the I/O interface carrier, connect the third-party device, power up and play. Like all DeltaV I/O, the Serial Interface may be added online while the rest of the controller and I/O is powered up and in use.
DeltaV Serial Interface I/O has a high level of reliability, providing the process availability required for most applications.
In certain situations, process availability can be increased through the use of Serial Interface I/O redundancy.
Benefits
Provides Seamless Information interface. Using the Serial Interface with the DeltaV system, you gain an extended view of your entire plant. All serial information is readily available for display at the Operator Interface.
When connected to a PLC, DeltaV software may pass supervisory information to the PLC facilitating the coordination of control strategies across systems.
Plug-and-play ease of use. Plug-and-play installation saves money. The Serial Interface works just like other DeltaV I/O interfaces. It fits into any available slot on the controller I/O carrier. There are no dipswitches. Just plug it in!

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.
