It is a standalone protocol converter that is easy to use and integrate, and it comes with dedicated functions, for example, troubleshooting. The third option is to use a Modbus protocol gateway. Both options require that engineers must be familiar with protocols’ behavior so that they are able to handle exceptions. It requires PLC programmability and additional expenditure.

The second option is to use a small PLC that supports software add-on protocol library or a hardware communication module. The cost may be relatively low from a hardware point of view, but it requires a software engineer who knows C language extensively. The first option is to write a program on an embedded computer or industrial PC. Protocol conversion is normally done in one of three ways. For factory or plant owners, this kind of integration ensures that they reap the benefits of the IIoT, such as reducing energy consumption while maximizing productivity. The most common protocol conversion is Modbus-RTU-to-Modbus-TCP conversion, and is usually required when metering devices, mostly using Modbus RTU, need to be integrated with SCADA systems, mostly using Modbus TCP. Since the advent of the Industrial Internet of Things (IIoT), protocol conversion has been the key to connecting legacy and multivendor devices to networks.

Now, there is good news: A user-friendly standalone gateway that guides engineers within 60 seconds through the whole configuration process makes protocol conversions much easier. Hence, it’s no surprise that they are always on the lookout for ways to sidestep these tedious steps. It is no secret that converting industrial protocols often comes down to burning the midnight oil, and engineers’ frustrations with this time-consuming task are duly noted.
