EIOC配置
EIOC在DeltaV的输入/输出网络级别配置
并且它不计入控制器节点
计数限制（每个系统限制为60个EIOCs）。层次结构
DeltaV Explorer中的EIOC包括：
„EIOC
z分配的模块–配置和运行的模块
EIOC内部。
z硬件报警–与
EIOC。
z PO1–EIOC端口，其中以太网设备网络
协议已设置。
z PDT–添加和配置以太网设备
在EIOC端口下作为物理设备（PDT）。
可配置的PDT数量会有所不同
取决于端口中选择的协议，以及
分配的设备许可数量。PDT可以
被重命名。
z LDT–在PDT下添加逻辑设备（LDT），以
根据协议配置信号或控制标签
已在端口级别选择的。DST许可证包括
应用于此级别。
EIOC许可
EIOC的许可证发放简单且可扩展。只需购买
EIOC的硬件组件，单工或冗余。
冗余不需要额外的许可证。然后决定
您需要哪个协议（允许每个EIOC使用一个协议），
并选择适当的许可证。接下来，确定数量
需要连接的以太网设备，并选择许可证
包含所需编号。一旦配置了EIOC
每个LDT将使用一个DST许可证，类型为
根据LDT中配置的高值确定
（以太网/IP控制标签集成协议除外）。
对于以太网/IP控制标签集成协议，
每个控制标签使用一个DST许可证。DST许可证为
根据配置的控制标记类型使用。
PRP不需要许可证，因为它是
EIOC功能。
总结
EIOC支持与以太网设备的通信
使用Modbus TCP、以太网/IP、IEC61850 MMS、OPC UA客户端
和以太网/IP控制标签集成协议。EIOC
支持用于监视或控制的大容量数据。

EIOC的能力适用于非常大的集成项目
控制需求有限。对于需要
批次或顺序控制（基于类别的单元、PLM、SFC、，
EIOC中不支持设备模块）
或需要其他功能的更复杂控件
例如传统、总线或电子编组IO
PK控制器或VIM2卡与DeltaV控制器组合
可能是更好的解决方案。请咨询当地艾默生

EIOC Configuration
The EIOC is configured in the I/O network level of DeltaV
Explorer and it does not count towards the controller node
count limit (limited to 60 EIOCs per system). The hierarchy
of the EIOC in DeltaV Explorer consist of:
„ EIOC
z Assigned Modules – Modules configured and running
inside the EIOC.
z Hardware Alarms – Hardware alarms associated with
the EIOC.
z PO1 – EIOC port, where the Ethernet Device Network
and protocol is setup.
z PDT – The Ethernet Devices are added and configured
under the EIOC port as Physical Devices (PDTs).
The amounts of PDTs that can be configured will vary
depending of the protocol selected in the port and
the amount of device licenses assigned. The PDTs can
be renamed.
z LDT – Logical Devices (LDTs) are added under the PDTs to
configure signals or control tags depending of the protocol
that has been selected at the port level. DST licenses are
applied at this level.
EIOC Licensing
Licensing for the EIOC is easy and scalable. Just buy the
hardware assembly for the EIOC, simplex or redundant.
No additional license is required for redundancy. Then decide
which protocol you need (one per EIOC is permitted),
and pick the appropriate license. Next, determine how many
Ethernet Devices you need to connect, and pick the license
containing the required number. Once the EIOC is configured
one DST license will be consumed per LDT, with the type being
determined based on the highest value configured in the LDT
(except for the EtherNet/IP Control Tag Integration Protocol).
For the EtherNet/IP Control Tag Integration protocol,
one DST license is consumed per Control Tag. The DST license is
consumed based on the type of Control Tag that is configured.
PRP does not require a license, as it is included as part of the
EIOC functionality.
Summary
The EIOC supports communications with Ethernet Devices
using Modbus TCP, EtherNet/IP, IEC61850 MMS, OPC UA client
and Ethernet/IP Control Tag Integration protocols. The EIOC
supports a huge capacity of data for monitoring or control.
The Capacity, polling and switchover times vary based on
protocol, device type, and loading. Refer to the DeltaV System
Planning Guide for more information.
The EIOC capacity lends itself to very large integration projects
with limited control needs. For applications that require
batch or sequence control (class-based units, PLMs, SFCs,
and Equipment Modules are not supported in the EIOC)
or more complex control that requires other functionality
such as traditional, bus, or Electronic Marshalling IO, then a
PK controller or a VIM2 card combined with a DeltaV controller
could be a better solution. Please consult your local Emerson
office for more details.
