A Simpler Solution With Lower Lifecycle Costs
ECT’s open-platform design approach helped save time and reduce complexity in deploying its customer’s compressor solution while meeting or exceeding all specifications.
“The PlantPAx system and Modbus/TCP communications allowed us to integrate everything together into a single platform,” Stoll said. “Had our customer gone with a proprietary solution, this would have required systems from as many as four different vendors. Just trying to get those systems to communicate with each other would have been a major project in itself.”
ECT estimates the Rockwell Automation solution could save its liquefied natural gas customer upward of 50 percent in lifecycle costs. This includes not only reduced integration costs, but also reduced support and operating costs.
“One system instead of four will mean fewer technologies for workers to learn and maintain,” Stoll said. “It also reduces the number of spare parts that need to be stocked and managed to support the system. And it allows our customer to potentially bring maintenance activities in-house that they otherwise would need to outsource to several vendors in a proprietary-systems approach.”
The open and integrated design approach also will offer greater efficiencies over a proprietary approach. For example, a proprietary approach would have required that operators work from as many as a dozen different panels and stations to initiate operations. The integrated platform will greatly simplify that process.
“It turned this very complicated sequence of getting the motor started into literally two button pushes for an operator,” Stoll said.
Also, because all of the platform’s control elements are integrated, operators and technicians will be able to access any of them from a single HMI, rather using a different HMI for each different system.
“With the PlantPAx solution, workers will be able to monitor overall production status, review a system’s performance, or look at trips and diagnostics – all from one screen,” Stoll said.
The results mentioned above are specific to Energy Control Technologies’ use of Rockwell Automation products and services in conjunction with other products. Specific results may vary for other customers.
