How PLCs are making programming and application management easier from remote locations

The world is in an era where digitalisation is the driver. It has therefore become vital for companies to deploy setups and applications that will allow them to add more value to their customers, while keeping costs down. To develop a sustainable business today, there is need for enhanced maintenance, cost optimisation, on-demand connection to installations, improved autonomy in the creation of applications and faster process implementation. To achieve this, many businesses are looking towards programmable logic controllers (PLCs).

Programmable logic controllers have changed the way OEMs operate. In that last couple of decades, PLC solutions have been developed and manufactured with onboard HMIs. This means that businesses that rely on specialty machines can now have full and modern remote controlled solutions, thereby reducing overall system costs and minimising the size of required hardware.


The PLC technologies of today also save businesses cabin space and remove the need to setup Panel-PLC communication.

These PLC solutions are designed as a single integrated programming environment. A good example is the Unitronics unistream. According to Steve, expert at “the best PLC solutions of today feature packaging that makes the writing of ladder logic and hardware configuration straight forward.”

The PLCs offer remote access features, which make it possible for application managers to access application units straight from their desktop. This can be done regardless of whether you are debugging or retrieving data. This is perhaps one of the main reasons why system integrators have fully embraced PLC solutions. The solutions can save time, money and inconvenience.

What you should expect from a good PLC solution

1. A good PLC solution should have communication between Panel and PLC built in.

2. It should be able to help the company reduce the hardware required to run processes.

3. It should provide a single programming environment. This will ensure a reduction in programming time.

4. There should be reduced wiring and reduced space requirements.

5. It must be open to a variety of communication networks.

6. It must be flexible enough to meet the needs of your business.

With these aspects, managing applications from remote locations will be easy and business processes will run faster. Businesses enjoying the benefits of using PLCs today include those in the manufacturing industry, travel industry, aerospace industry, printing industry, food industry, textile industry,
hospitals, film industry, plastics industry, agriculture, and the leisure industry. They all use PLCs to varying degrees but they are part and parcel of their business processes.

It is best to hire a specialist to ensure proper integration of the systems into your business. You can do this by hiring outsourcers or getting people on full time, or by engaging the
services of the company you are buying from. If it is a new area for you it doesn’t have to be daunting, and you can begin enjoying the benefits in your organisation very quickly.
