Introduction

Industrial communication protocols enable communication between industrial devices and systems. Over the past few decades many industrial communication protocols have been developed, each designed for a specific purpose and environment. These protocols are the foundation of connectivity in and across industrial networks. Generally speaking, industrial networks can be segregated into four different layers:

  • Field Layer: Here the nodes consist of transducers, actuators or sensors. These communication devices collect process control or environmental information and transmit it back to the controlling or monitoring systems. They also execute the field commands, such as physical rotor shift.
  • Control Layer: As the name suggests, this layer consists of logic controllers, such as PLCs or distributed control systems (DCS). Their main role is to provide local control to different equipment in a plant.
  • Supervisory Layer: This layer includes a SCADA/HMI for better control and supervision of crucial industrial activity.
  • Execution and Planning Layer: This layer is a crucial link between the business and operational priorities. Enterprise resource planning is an example of a function which is carried out in this layer.

We at Utthunga have a team of experienced professionals to develop customized hardware and software for your industrial connectivity needs. Our development capabilities include popular industrial communication protocols such as HART, FF, PROFIBUS, PROFINET, Modbus, EtherNet/IP, etc. in the Field and Control layer. We are one of the premier OPC based development company providing connectivity solutions from the field level to the execution level and beyond to the enterprise/cloud layer also.

Why Industrial communication drivers/protocols required for Industries?

Industries are gearing up to make the best of the technologies offered by the industrial revolution in all its advanced forms. Industries need seamless industrial connectivity to stay ahead in these times of rapid digitalization. Fast, easy and secure exchange of data across the various layers of devices and systems is a must to unlock the hidden power of data. As this data moves upwards from the sensors to the cloud, at each level the data is being processed and analyzed and handed over to the stakeholders for faster ad informed decision making at that level.

In order to meet the demand for high-speed connectivity between industrial systems, we are also witnessing transition to the faster Ethernet based communications protocols. With numerous protocols, each with their unique capabilities and limitations flooding the industrial communications market, we at Utthunga help you to adopt and implement the communication protocol of your choice that best meets your needs.

FAQs

1. How do instruments and controllers communicate in a process control?

The data from the instrumentation devices such as valves, transmitters, etc. is used by controllers to perform functions such as opening or closing valves and measuring process parameters. The controller receives this data in analog (more common) or digital (getting popular) form and generates control signals, which are sent over the communication buses to the field devices to control the operation of that process.

2. What to consider when planning, designing and implementing an industrial communication network?

For successfully planning, designing and implementing an industrial communication network, you need to consider the following:

  • Reliable network structure
  • Robust security protocols
  • Transparency in network management
  • Remote access to machines
  • Integration with cloud infrastructure
  • Personnel and machine function safety
  • Access to devices through HMIs, mobiles etc.

3. Why are there so many different industrial protocols?

The leading industrial OEMs build products that have their own connectivity need in terms of speed, security, easy of configuration, relaying key alerts, etc. Over the decade these OEMs built and promoted protocols that were built in their labs addressing their unique product/ecosystem needs. What we ended up with are silos/islands of devices and systems that are not always interoperable. The good news is that we are already in the middle of this huge shift towards standard protocols like OPC, MTConnect, etc.
