Communication : TagWell


SoftPLC Corporation's TagWell solution provides IIoT - a powerful and configurable platform for comprehensive and scalable remote control system management.

TagWell utilizes Internet cloud technologies and low-cost M2M cellular communications. Combined with our field-proven industrial controller and communications gateway product lines, the TagWell solution makes it easy to remotely monitor, control, acquire data, and troubleshoot remote systems, machines, and other devices via Internet connections including cellular, radio, or satellite networks.

    TagWell Functions

    TagWell provides an efficient, low cost, and bi-directional pathway to remote systems for alarming, data acquisition, and control. The TagWell user interface is customer specific web pages that can be viewed on any browser.

    • Designed with cellular or other non-wired ethernet communications in mind, TagWell utilizes an efficient and secure protocol for data transfer to/from SoftPLC Remotes, thus minimizing the bandwidth required.
    • Intelligent SoftPLC Remotes can send data to TagWell only upon user-specified conditions or intervals, further minimizing required bandwidth.
    • Alarms can be sent via email or text messages to any number of users, including escalating lists if no response is received within user defined time periods.
    • Remote nodes can send data to each other via TagWell.
    • Aggregate data across any number of remotes into a single Tag Table in the cloud.

    • RS-485 serial or wireless interfaces allow connection to devices over long distances - allows for flexible deployment in a wide range of operating conditions, hazardous areas, etc.
    • User programmable - logic determines when data transfer is initiated - time, events, events within a defined threshold, etc.
    • Logic functions for I/O control, data manipulation (eg: averaging, scaling, etc.) and more
    • Alarm notification via email and/or text messages
    • Data Logging - Remote based logs in the event of communications loss, transfer logs to TagWell and/or email logs as attachments

    TagWell Services and Related Products

    TagWell systems include 2 categories of products:

    • SoftPLC Remotes - Any SoftPLC Controller or Gateway can be a TagWell remote. These are world class, modern industrial I/O controllers and communication interfaces that enable remote communication between other vendor's controllers or equipment and TagWell, as well as from TagWell to SCADA systems. SoftPLC Remotes can also provide immediate alert notification via Email or SMS text message, and can do data acquisition and logging functions. SoftPLC Remotes can be equipped with cellular modems, and also have serial and ethernet ports to enable other type connections via the internet to TagWell, such as radio modems, satellite, phone lines via dial-up accounts, etc.
    • TagWell Platform, Communications and Engineering Services - Secure Internet based ("cloud") data center and communications services that provide access to/from SoftPLC Remotes, enable real-time browser-based remote monitoring and control of industrial systems, send Email and text messages (eg: remote alarms and reports), and run customer specific application programs. Included are cloud subscription services, cellular M2M plans, TagWell web page and application development, and logic programming for SoftPLC Remotes.

    TagWell Engineering Services

    SoftPLC Corporation and TagWell qualified System Integrators provide programming and application engineering services to develop customer specific applications, such as:

    • Web Pages compatible with TagWell
    • SoftPLC Web Studio Dashboards compatible with TagWell
    • Application logic for SoftPLC Remotes
    Example TagWell Application Programs

    Data sent to TagWell can be accessed by applications running in TagWell or on any computer connected to the internet. For example:

    • Data can be aggregated onto a single web page for an overview of all (or groups) of remote sites
    • Data can be read from or written to a database or SCADA system
    • Multiple transmissions of data from any number of sites can be aggregated to a customer specified format and sent periodically (eg: daily, hourly) as a single file to customer designated locations via customer designated protocols

    Contact us to discuss your application requirements. There may already be a TagWell application that meets your needs (or something similar that can be easily modified), or one can be created by SoftPLC or one of our Integrator partners for a very reasonable development cost.

    Example TagWell Application

    Tank Monitor cell appl

    XYZ company sells liquid chemicals to end user companies, including the service to ensure the tanks are always filled. To ensure their customers experience no downtime and to reduce the logistics costs of delivering the chemicals (fuel, man-hours, etc.), XYZ decides to implement a TagWell based remote monitoring system. The system includes:

    • a Micro SoftPLC Remote at each tank that monitors the level and system status, sends the information to TagWell once per hour and sends low level alerts via email to XYZ headquarters
    • a 1MB/month cellular plan for each Remote
    • a TagWell web page that displays the current tank level at each site, any pending delivery status, and alerts
    • the TagWell web page allows a driver to update delivery status when en-route and when at the site
    • a custom TagWell application that consolidates the information from all sites into a single file and transmits it every 4 hours to a SQL database at XYZ headquarters, where their logistics software determines future delivery schedules based on the reported information

    The ROI on the application development of this system was under 2 months, the cost of each Remote (including Micro SoftPLC, cell modem, I/O, enclosure) is under $750 and the annual TagWell Subscription and Cell Plan is less than the cost of 6 gallons of diesel fuel or 1 hour of labor!
