 Press Releases

  • ISA100 is an open-standard wireless networking technology developed by the International Society of Automation. The protocol utilizes a time synchronized, self-organizing, and self-healing mesh architecture, forming full mesh network topologies. The protocol currently supports operation in the 2.4 GHz ISM Band using IEEE 802.15.4 standard radios. Developed as a multi-vendor, interoperable wireless standard, ISA100 was defined specifically for the requirements of process field device networks.

    The NIO200 ISA100 product family includes three infrastructure devices that address all mesh environment needs for deploying ISA100 Wireless networks.

    • NIO200IAG:        ISA100 Compliant All-in-One Gateway 
    • NIO200IDG:       ISA100 Compliant Distributed Gateway 
    • NIO200IDR:        ISA100 Compliant Backbone Router

    Technical Primer - ISA100 Wireless Logical Roles

    Building blocks in ISA100 Wireless are called roles, where a given device might fulfill multiple roles. The NIO200 product family fulfills the infrastructure roles listed in the table below.


    Role Definition and Responsibility

    Backbone Router

    The Backbone Router mitigates between devices operating in the wireless subnet and devices operating on the backbone infrastructure.

    System Manager

    The “brains” of the network. Manages all network devices through policy controlled configurations based on collection of performance parameters reported.

    Security Manager

    Enables, controls and supervises the secure operation of all devices present in the network via standards compliant security policies.


    Provides an application interface between the ISA100 network and entities residing on the plant network.

    System time source

    Responsible for maintaining the master time source of the network.

    Note: This is just a list of the logical roles fulfilled by the NIO200 products family and not a comprehensive list of ISA100 logical roles.

    Solution Highlights

    Each NIO200 ISA100 infrastructure product showcases the following features:

    •   Robust wireless connectivity with support for path redundant, mesh topologies for
      • The ISA100 wireless subnets composed of field instruments
      • Backbone infrastructure via Wi-Fi Mesh technologies
    • High throughput rate Wi-Fi backbone
    • Dual Wi-Fi Mesh path diversity ensures optimal reliability for communications over the backbone
    • Wide temperature range, high EMC immunity to Surge, ESD and EFT Suitable for deployment in hazardous environments
    • Incorporates power redundancy (DC & PoE)

    Deployment Topology Scenarios

    ISA100 network deployments are either single subnet (“All-in-One”) or multiple subnet (“Distributed”). The deployment topology end users and vendors choose for their ISA100 Wireless deployments are influenced by various factors such as:

    • Scalability requirements – number of field instruments deployed 
    • Layout of the facility
    • Geographic area that needs to be covered
    • Financial and budgeting constraints

    Single Subnet “All-In-One” Deployment Topology

    Key Characteristics:

    • Single subnet - no backbone networking infrastructure
    • Simple network
    • Typically consists of less than 100 field instruments
    • Instruments deployed are typically in close proximity to each other

    Multiple Subnet “Distributed” Deployment Topology

    Key Characteristics:

    • Multiple subnets connected via IPv6 enabled backbone networking infrastructure
    • Complex network
    • Typically consists of hundreds of field instruments
    • Instruments deployed are scattered throughout the facility

    NIO200IAG: All-In-One Gateway                                                                                                                                                   

    The “All-In-One Gateway” hosts the the ISA100 System/Security Manager, Gateway and Backbone Router roles. It manages the subnet composed of field instruments arranged in a multi-hop wireless mesh configuration. This product is best suited to be used in a single subnet “All-In-One” topology.

    Topology Considerations



    Gateway is installed outdoors

    Typically close to control room

    Determining optimal location  is vital

    Simple network deployment

    Low cost installation and maintenance

    Limited scalability

    Limited geographic coverage

    Deeper mesh networks resulting in:

    • Higher power consumption, shorter field battery life  
    • Increased communication latency  
    • Decreased network throughput

    NIO200IDG: Distributed Gateway                                                                                                                                                 

    The “Distributed Gateway” hosts the ISA100 System/Security Manager and Gateway roles. It manages multiple ISA100 subnets federated by NIO200IDR Backbone Routers, and allows for multiple subnets that form a distributed topology which maximizes geographic coverage and scalability.

    Topology Considerations



    Gateway is installed in the control room

    BBR’s deployed throughout the facility

    Wi-Fi Mesh backbone simplifies deployments

    Increased Scalability

    Extended geographic coverage

    Shallow mesh networks resulting in:

    • Optimized power consumption increasing field battery life  
    • Lower communication latency  
    • Increased network throughput

    Network deployment more complex

    Increased cost of installation and maintenance

    NIO200IDR: Backbone Router                                                                                                                                                       

    The NIO200IDR is an ISA100 compliant, cost effective Backbone Router. It manages wired and wireless backbone connectivity to the ISA compliant wireless field instruments. This type of router is deployed in conjunction with the NIO200IDG Distributed Gateway.

    Topology Considerations



    Gateways are installed in optimal locations throughout facility

    Architectural support for wired connections is needed

    The distributed approach includes data routing plans that increase optimization, and decrease bottlenecks

    Network capacity can scale and increase linearly in a cost effective manner

    Optimal path diversity and resiliency

    Network deployment more complex
