A lack of certified trained employees results in numerous problems that can end up costing a company money and even the ability to stay in business. In the past, many companies did not require any kind of PLC certification for their employees. That's because certification programs were very expensive and difficult to set up. In addition, the available certification materials were substandard or irrelevant. Unlike the work environment of the past, however, today's companies are finding it crucial to certify all of their employees on PLCs.
Certification is no longer a luxury.
Without certification, results can be disastrous. For instance, if only one person knows how to fix a PLC and that person leaves the company, the company is left with only a few unpleasant choices. One, the company can pay someone else lots of money to come in and fix the problem. Or two, it can live with the consequences of downtime while another employee learns about PLCs. For many modern industrial companies, these are simply not options.
