The automation is the buzz word of the current world; from office to commercial set up and industrial floor each sector is relying on the automation system to improve efficiency, accuracy, and speed. Especially, industrial floors are witnessing a new wave of automation that propagates end-to-end communication between switches and terminals.

Let’s Communicate

Industrial Ethernet DH+ has greater implication when it comes to two-way communication. Let’s discover how it works so that we can understand the underlying benefits and advantages on the industry floor.

For instance; a wine bottle filling automation uses “clapping” to ensure delivery of the message. The Automation controls the PLC command and the PLC is responsible for sending the stop filling command when the bottle gets filled. And in case the command gets lost during the transition, the PLC is aware of the mistakes and resend the command; otherwise, it would have been resulted in spillage thus wasting money and time.

Let’s look at its mechanism and how it helps the communication process between the various components on the industrial floor.

  1. First, the Ethernet is an open loop protocol that uses time-deterministic message format so that the critical data does not get lost or arrive late.
  2. It has both implicit message format meant for real-time I/O communication and explicit message format that carries out general communication and message delivery between devices.
  3. The Ethernet automation network enables the technicians to remotely access the operational process. For instance, using the 1784-u2dhp cable, you can monitor the bottle filling process mentioned above. In brief, it streamlines the whole process without any intervention of the manual operator. All they can do is just sit back and monitor the whole process.
  4. The Ethernet network uses TCP/IP format to communicate between HMI, the controllers, and PCs. And it is also applied to carry out communication between Motion controller, PLC and remote I/O racks. Both these protocols can coexist in a single-tiered network and the capability of sending prioritized messages in milliseconds makes it perfect for motion control application.

You simply cannot just build an Ethernet network and expect it to work perfectly; in fact, you have to consider a few key factors before you get down to draw the blueprint. The below mentioned are the important aspects.

Operation

For instance; you have prepared an Ethernet network for the tempered glass manufacturing unit, where the glasses go through constant heating and cooling process. And if in between the process, the system and line get seized, you will be left with leftovers of useless glass sheets. So, ensure that you look at the operational aspect carefully.

Environmental factor

Particularly, cold ambiance is damaging for the cable because of a near freezing temperature the cable will brittle, break or get damaged easily. And relatively hotter environment also has the damaging effect. Therefore, the balancing the temperature becomes so much more important.

Noise

Electromagnetic noises generated by large motors and high-power devices can hamper the data transfer resulting in corrupt messages.

Security

Security should be the primary concern. As the data security is important in a commercial network, the industrial floors also need the same type of security. In addition, the workers on the floor can break the network, creating a break in and break out like scenario.

The commercial Ethernet network follows star topology while the industrial network will have varying kinds of topologies such as treeline, ring, and star. Depending on the usage, the network can be classified into two distinct categories; heavy and light duty.

While the light-duty commercial cable can be a little lesser in quality, the heavy-duty cable must have the better jacket that is thick and these cables will cost you more than the light duty cables.

The automation will enhance the productivity and the accuracy of the production. And the Ethernet in comparison to its predecessor Fieldbus is a far better option. And over the time, it has gone through evolution; once considered to be the best communication card 1784-PCMK has gone obsolete.

You have to keep updating yourself with the current trends if you want to deploy the Ethernet automation on your industrial floor. You have to have technological capability and understanding so that you can introduce the system cleanly.

You also need to train your engineers and workers to operate in the networking environment diligently. You must have a team to look after the complete networking system that might add up to your operational cost. However, it makes sense to deploy the technology as far as accuracy and productivity are concerned.

Over the time, the Ethernet has come a long way; it might have learned to cope with the harsh environmental conditions, but it still remains Ethernet. Therefore, before you apply the technology, make sure that you have assessed all the functional aspects correctly.
