Softing Offers Practical Replacement for Discontinued Communications Module
Softing Industrial’s usbLink CN serves as a USB-to-ControlNet interface that aims to maintain connectivity for users needing to link laptops to industrial field devices for configuration and troubleshooting tasks.
Machine Design reached out to Softing to learn about the design challenges, user experience, R&D process, sustainability and use cases for the device. Deane Horn, director of product management, provided answers, adding, “As part of the Rockwell Technology Partner Program, we are happy to have a relationship with Rockwell that allows us to take on product lifecycle extensions that help customers extend the life of their legacy applications.”
Key features of the usbLink CN include:
- USB 2.0 for laptop connection and RJ45 for ControlNet connection
- Use with RSLinx and RSNetWorx to configure the network and field devices
- Use RSLinx version 2.51 or later
- Use RSNetWorx for ControlNet to communicate with devices via RSLinx
- LEDs indicate USB status, module status, and ControlNet network status
Addressing Practical Challenges
The usbLink CN is designed for system integrators and end users who require the ability to connect laptops to ControlNet networks, Horn said. The previous reliance on Rockwell's PMCIA card for this connection has become impractical due to the decline in laptop support for PMCIA. The usbLink CN now provides a necessary solution for those who need to configure, troubleshoot or view network parameters in ControlNet systems.
One consideration for integrators is that they often do not build the machines they work on, Horn pointed out. Those are created by OEMs who may use proprietary tools. “For a while, it just runs—no issues,” Horn said. “At some point, there may be problems, or necessary modifications, but the customer doesn’t have a way or tool to connect to ControlNet debug, edit or change. usbLink CN is the tool (interface) that allows the user to connect a laptop to ControlNet and perform the functions needed.”
User Experience and Interface
When asked what makes this product intuitive or user friendly for design and mechanical engineers, Horn said, “What makes the usbLink super intuitive is that the end user can use Studio5000 on their laptop to configure controllers or RSNetWorx (also on their laptop) to configure the network or devices.”
Knowing the node ID of the usbLink CN is all that is necessary for establishing a connection, simplifying the setup process. This interface is straightforward for users experienced with RSLogix software, promoting efficient interaction without requiring extensive retraining or adaptation.
R&D, Sustainability, Application Insights
During the development of the interface, Horn said Softing explored adding a ControlNet traffic analyzer using off the shelf Netdecoder software. While this capability was tested, it was ultimately not included in the final product due to insufficient demand.
With regard to sustainability, Horn says the company adheres to WEEE regulations for the treatment and recycling of electronic equipment and RoHS guidelines for reducing hazardous substances and products. The usbLink CN is built for durability and is flashable, allowing for upgrades instead of requiring complete hardware replacement. Such features contribute to a longer product lifespan and reduce environmental impact, Horn said.
The usbLink CN has practical applications in a range of settings, such as with OEMs. For instance, Horn says an OEM of gas turbines includes the tool with their systems, enabling users to connect laptops to ControlNet networks for configuration.
