As process systems age it is common for the industrial control systems that help them operate efficiently become obsolete and unsupported by the manufacturers. This problem is compounded by many smaller manufacturers exiting the market to be replaced with a few large international manufacturers.

In addition to manufacturers supporting fewer PLC and process system controls technology continues to race ahead faster than ever before. This all leads to a lack of support for older models – requiring any facility to upgrade or modernize their process system controls or PLC before problems occur.
