“The CENTERLINE MCC also provides the functionality to remove a component for maintenance, close the door and continue to run without any danger to the operators. If you compare this to the older MCCs, you would need to shut down the whole system while the component in question was being worked on,” said Andrew.
“The solution was developed using Studio 5000® and we also incorporated aspects of the PlantPAx® libraries. The temperature, pressure and flow equipment is all supplied by Endress+Hauser which integrates well with the Rockwell Automation system,” explained Andrew.
The plant used Ethernet communications to provide the capability for premier integration of the Rockwell Automation Connected Components as well as mass flow meters from Endress+Hauser, a Rockwell Automation Strategic Alliance Partner.
The complete system was built as a containerised solution and assembled and tested prior to being packed and shipped to Europe. Upon arrival the system will be installed and commissioned by engineers from the enduser plant and ACS.
As the MCC is operating in close proximity to the operators, ArcShield™ protection was included in addition to the Rockwell Automation Connected Components. ArcShield helps to reduce arc flash hazards and provides increased protection against electrical arcing faults.
The MCC also features IntelliCENTER® technology, which enhances the intelligence of the MCC by using built-in networking to capture information that can be used for predictive maintenance, process monitoring, and advanced diagnostics.
Connecting motor control devices over Ethernet allows operators to realise the benefits of The Connected Enterprise by monitoring and analysing operations from anywhere at anytime.
“The international certification via IEC61439 combined with ArcShield protection helped the customer to feel relaxed in the knowledge that they are purchasing a superior product, which provides the highest levels of protection for their operations staff,” explained Andrew.
“In addition the equipment that is included as part of the MCC allowed us to achieve a high category of machine safety, for example we can use PowerFlex 525 drives with built in safe torque off and achieve a Category 3 machine safety with no additional hardware for the drives,” he said.
ACS leveraged their engineering expertise to incorporate several custom selections, including a light and power distribution chassis, PLC tier including dual CompactLogix controllers and Stratix® switches, and custom heat trace control cubicle.
