Before installation, ABB performed a thorough analysis of the application software to ensure that it would meet all specifications and be highly reliable.
To ensure that downtime would be minimal, ABB specialists performed their tasks in steps. Importantly, they used the interfacing station to operate the Operate IT and Contronic P simultaneously. This significantly reduced risks.
Throughout the transition, the ABB service team drew on their expertise to save money for the steel plant. For example, ABB was able to retain the plant’s existing I/O modules, and avoid the need for I/O checking and loop check. By making the most of both the old and new equipment, and lowering risk, ABB kept the upgrade cost-effective.
To keep costs low in the future, the company opted for a life cycle extension contract that will keep the I/O in operation until 2012.
During the upgrade, the company worked with ABB specialists they had worked with previously, giving them an extra measure of confidence.
