GRID45. One Module.
Every Major Industrial Protocol.

GRID45 is your one-stop industrial networking solution: An all-in-one module designed for both wired Ethernet and wireless connectivity. With a single integration, you gain access to Modbus TCP EtherNet/IP, BACnet IP, and numerous other protocols. No need to integrate multiple vendor’s modules.

Every Major Industrial Protocol. One Module

GRID45 is the engineer's answer to protocol versatility. By integrating with a single module, you unlock access to all the top protocols, including Modbus TCP, EtherNet/IP, BACnet IP, PROFINET (coming), and the promise of more in the pipeline. Understand your customers, anticipate their protocol preferences, and deliver tailored solutions without the hassle of multiple integrations.

Breathe New Life in Old Products. No Complete Redesigns

GRID45 enables you to easily add Industrial automation protocols into your existing products by reusing the existing firmware and avoiding the exhaustive efforts of a total redesign. Not only does GRID45 keep your established systems intact, but it also offloads the weighty tasks of network and industrial protocol processing from your host processor.

Eliminate the Overhead of Protocol Development

Developing, deploying and maintaining the growing number of Industrial Communication protocols is expensive and difficult for device manufacturers. The resources required are considerable, and the effort is a distraction from developing core application features for the device manufacturer’s products. GRID45 eliminates this expense and difficulty.

Customization Made Effortless

GRID45 is built to enable device manufacturers to add the customizations they need to make their data actionable. Based on extensive customer research, we've designed our module to encompass 80% of typical application requirements right off the bat. And the remaining 20%? We can fine-tune it according to your OEM requirements, whether that means mapping product data directly to the network protocol or sending it to the cloud.

Simply contact our team, detail your customization needs, and we'll ensure you receive a module tailored to your exact specifications. For a seamless testing experience, sample firmware is readily available upon request as well.
