配置EIOC控制模块时，可使用连续运行所需的所有典型功能块；然而，以下功能块在EIOC中的使用受到限制：„256 DC、EDC和DCC–用于MCC中的电机控制等应用。„26 PID–模拟控制，其中所有或大部分信号来自以太网设备。„16 SEQs–用于排序电机控制状态的顺序功能块。„16 STD–用于排序的状态转换图，可与SEQ功能块一起使用。„EIOC不支持批次控制、SFC、PLMs和设备模块。为保持EIOC的能力，应考虑保持模块尽可能精简。模块中的重型配置将减少EIOC中2000个模块的容量。以下是EIOC可用功能块的完整列表，按类别列出。控制–无功能–状态转换、步进定序器模拟控制–模拟跟踪、计算/逻辑、滤波器、输入选择器、定标器、信号表征器、信号发生器、信号选择器、偏置/增益、手动加载、PID、速率限制、斜坡、增强斜坡、拆分器、限制能量计量–无IO–报警检测、AI、AO、DI、DO标签I/O–DI、DO、AI、，AO Logical–All Math–All Special Items–All Timer Counter–All Simplex EIOC（保护盖安装在双水平载体的冗余EIOC插槽中）。从EIOC控制模块访问DeltaV Live graphics、DeltaV Operate graphics以及报警和历史记录收集遵循与DeltaV系统控制器中运行的控制模块相同的规则和机制。EIOC安装在双水平载波上，包括冗余电源输入终端和冗余以太网隔离端口。以太网隔离端口将冗余DeltaV控制网络通信与冗余以太网设备网络隔离。建议使用工业网络防火墙，以提供基于深度数据包检查的附加安全性，从而限制以太网设备和以太网协议级别的通信。这样，就确保了健壮性和安全性。

When configuring the EIOC Control Modules, all typical Function blocks needed for continuous operation are available; however, the usage of the following Function blocks are limited in the EIOC: „ 256 DC’s, EDC’s and DCC’s – used for such applications as motor control in MCCs. „ 26 PID’s – analog control where all or most of the signals are coming from Ethernet Devices. „ 16 SEQs – Sequence function block used for sequencing motor control states. „ 16 STDs – State Transition Diagram used in sequencing and can be used with the SEQ function blocks. „ Batch control, SFCs, PLMs, and Equipment Modules are not supported in the EIOC. To maintain the capacity of the EIOC, consideration should be taken to keep modules as lean as possible. Heavy configuration in the modules will decrease the capacity of 2000 modules in the EIOC. Listed by category, the following is a complete list of the function blocks available with the EIOC. Advanced Control – None Advanced Functions – State Transition, Step Sequencer Analog Control – Analog Tracking, Calc/Logic, Filter, Input Selector, Scaler, Signal Characterizer, Signal Generator, Signal Selector, Bias/Gain, Manual Loader, PID, Rate Limit, Ramp, Enhanced Ramp, Splitter, Limit Energy Metering – None IO – Alarm Detection, AI, AO, DI, DO Tag I/O – DI, DO, AI, AO Logical – All Math – All Special Items – All Timer Counter – All Simplex EIOC (Protection cover installed in the redundant EIOC slot in the dual horizontal carrier). Access to DeltaV Live graphics, DeltaV Operate graphics, and the alarms and history collection from EIOC control modules follows the same rules and mechanisms as control modules running in the controllers in a DeltaV System. The EIOC mounts on the dual horizontal carrier, which includes redundant Power input Terminals as well as redundant Ethernet Isolation ports. The Ethernet Isolation ports isolate the redundant DeltaV Control Network communication from the redundant Ethernet Device Networks. An Industrial Networks Firewall is recommended to provide added security based on deep packet inspection to restrict communications at the Ethernet device and Ethernet protocol level. In this way, Robustness and Security is ensured.
