When systems are down, time and productivity are lost, which in turn, means money is lost. Naturally, engineers will want to fix the problem quickly. But troubleshooting isn't always easy, especially when it comes to troubleshooting protocol gateways, which have become indispensable in the era of the IIoT. Engineers' time and energy are often misspent trying to track down the root cause of a communication failure. Adding to their frustration is the lack of helpful diagnostics tools to pinpoint the root cause much faster. This white paper takes a closer look at troubleshooting methods and their pain points. Moreover, this white paper sets out to present a solution that simplifies the troubleshooting of protocol gateways.
