AB Legacy PLCs

Allen Bradley control solutions set the standard with the invention of the programmable logic controller nearly 30 years ago.  New times create new needs however and updated or upgraded solutions are often required. Many systems installed years ago are now obsolete and difficult to support. To compound things a system’s reliability becomes increasingly questionable as time passes. After a period of some years the rate of failure of any system starts to climb, the net result being that a control system which has been running processes reliably for the past several years often ends functioning on borrowed time. When system failure occurs getting a system running again will often be cost prohibitive. Indeed it is often the case that documentation and software for legacy systems is hard to come by.

HG Systems is well placed to solve the 21st century manufacturing challenges of lowering costs, improving throughput, improving quality and increasing flexibility. Highly integrated control solutions are available from HG systems if you wish to replace or upgrade existing control systems to help you to solve these challenges. The benefit of upgrading comes in time savings, cost savings and faster start-ups, all of which result from the installation of pre-integrated products designed to work together coupled with the service range available from HG Systems. The services available from HG are designed to guide you from initial conception to ongoing maintenance, ensuring that you get a long term solution for your automation needs.

HG Systems are able to help you with independent advice and guidance. By partnering with the leading manufacturers in the automation sector we are able to reverse engineer most processes. This enables HG to replace a control system, regardless of type or make, with a modern equivalent that is well documented and supported.

Reasons to upgrade before system failure:

• Time:- A system change over can be timed to suit production demands so as to minimise the impact on production.
•  Functionality improvements:-  If the control system upgrade is left until failure occurs then there will be a high pressure situation to get the new system in and running again as quickly as possible. This leads to any potential production improvements being left low on the priority list meaning that they may not be implemented. Once the upgrade has occurred this could mean that the system continues to run as it did prior to the change.
• Cost:- An upgrade executed under an emergency situation will cost more both in the sort and long term.

HG Systems has reversed engineered and upgraded many Allen Bradley PLC’s, which means that our engineering staff are capable of developing and upgrading  your system with modern, supportable solutions.
