·100base-T快速以太网：与10base-T的区别在于将网络的速率提高了十倍，即100M。采用了FDDI的PMD协议，但价格比FDDI便宜。100base-T的标准由IEEE802.3制定。与10base-T采用相同的媒体访问技术、类似的步线规则和相同的引出线，易于与10base-T集成。每个网段只允许两个中继器，最大网络跨度为210米。
·IEEE802.3/Ethernet(以太网):最广泛的媒体访问技术,通常在OSI模型的物理层和数据链路层操作。是Novell、Widows NT、IBM、UNIX网络 LANServer、DECNET等低层所采用的主要媒体访问技术，组网方式灵活、方便、且支持的软硬件产品众多。其速率为共享型10Mbps。根据不同的媒体可分为：10base-2（同轴粗缆）、10base-5（同轴细缆）、10base-T（双绞线）及10base-FL（光纤）。
·NETBIOS/NETBEUI:NETBIOS是局域网软件接口的工业标准，可支持多种传输媒体。NETBEUI是NETBIOS的扩展用户接口，为Microaoft Windows NT和IBM的LAN Manager所采用。NETBIOS研制较早，比较简单，未考虑网间互连的情况，其命名方案不适合多种操作系统。
Cluster I/O 200 Series I/O See Chart below for 200 Series part #s The 200 Series Field Bus Modules are the latest generation I/A Series I/O modules. The DIN rail mounted FBM subsystem provides a reliable, high speed communications interface between the host control processor (for example the I/A Series control station) and field I/O sensors and actuators. It incorporates innovative equipment packaging, and the use of fiber optic and/or coaxial cabling between modules to allow local or remote distribution of process I/O points. The DIN rail mounted Fieldbus Modules (FBMs) are compact, high-performance distributed process I/O modules. They perform the signal conversion required to interface the electrical input signals to/from the field sensors to the optionally-fault-tolerant I/A Series control station. Communication between the FBMs the I/A Series control station is via Fieldbus Communication Modules (FCMs), which interface the 2 Mbps module Fieldbus used by the FBMs with the 10 Mbps Ethernet trunk Fieldbus used by the I/A Series control station. The FBMs automatically accept communication from either communication path (A or B) of the redundant Ethernet trunk Fieldbus. Thus, if one path fails, communication is not interrupted.

V4.3 The Ethernet MESH Network (V8.x) S20 The Mesh Network represents the next revolutionary step of the I/A Series Control Network functionality, Version 8.0 release introduces unprecedented communications capability, versatility and performance to I/A Series process automation systems. The Mesh network structure provides alternate communications paths between all stations that allows for faster, more reliable communications. Standard Commercial Off-The-Shelf (COTS) switch technology and components employ the Rapid Spanning Tree Protocol (RSTP) to manage traffic paths and provide a self-healing, redundant network that can recover from multiples faults. based on open standards, the Ethernet Mesh Network also lowers deployment costs by moving away from expensive proprietary networks to a low-cost standard network that can be easily maintained. This network also provides an infrastructure for information sharing between manufacturing and back-office systems.
