What is Modbus?

We all by now, know about the massive craze over the ideology of internet of things, wherein, the internet is connected by various devices and items, rather than the usual human to machine one, that is previously, the machine was connected to the human, and that it would be up to the human to operate it, but now, machines can connect to each other, and can carry out commands without any human intervention.

The whole concept of machine to machine (M2M) has been an integral part of the internet of things, and has really helped in increasing productivity in many industries and has allowed people to connect their devices to hurry up many different processes. M2M usually includes the process of industrial instrumentation, where a device like a sensor or meter can capture an event, and then that is connected through a network, it can be wireless, wired or hybrid to an application that will then translate it into meaningful information.

Now, here is where the system of Modbus comes into play, which is a serial communications protocol, which was first published by Modicon, in 1979 to use with their programmable logic controllers (PLCs). But it has gradually become the go to communications protocol, because of its simplicity, the fact that it is openly published and royalty- free, extremely easy to deploy and maintain and is now commonly available as a means of connecting industrial electronic devices.

The use of Modbus, for industrial communication between the many devices has been a great help as it has made it easier to transfer information without the risk of misinforming or leaving out even the tiniest bit of information. Modbus has also been important in the inclusion of machine to machine communication within the corporate or industrial work environment.

Network of networks: Benefits of M2M communication

For years, the machines have been making our lives easier. We live in a world where we cannot even imagine the absence of cars, mobile phones, fridges, computers and other machines related to our daily routine!

But an emerging concept seems to be taking the ease to a whole new level. With the application of modern networking technology, the Machine To Machine (M2M) connectivity has become possible, and now we don’t even have to tell the machines what to do. The machines talk to each other and connect with each other through a system called “telemetry”.  This M2M communication makes workflows simpler and complex processes leaner.

Here’s a list of some of the benefits of M2M communication.

• Monitoring: The M2M system can observe the status of the devices connected to it and the environment around it. Modbus for example enables communication among many devices connected to the same network and measures the features such as temperature and humidity.

• Managing remote machines: Diagnosis and maintenance are important for cost effectiveness of machines. An M2M system lets you carry out such tasks remotely and you don’t even need to be on site for this. Travelling to fix things up is no more required.

• Optimization: Won’t you like it if your machine responds to the environmental conditions on its own and takes care of itself? With M2M communication, that has become possible. For example, a machine closes the skylight when it starts to rain. Also, it calculates the optimal routes for delivering supplies.

• Identification: With M2M communication, your machine would respond to you about the area that requires attention. A machine would send you signal when it needs maintenance or when it has started to show some irregularities! Thanks to M2M, the identification of critical problems has become so much easier!

We often think that the technology cannot get better than this and then it surprises us- all over again!
