Agidens’ solution involved the migration of the existing control system to PlantPAx and the use of the PlantPAx Process Objects Library. The solution was designed with a focus on high availability; integrated safety; open standards; and information security and maintainability – with the main focus here being on integrity, availability and confidentiality.
The process control system – designed to be deployed over two phases – included PlantPAx process and safety controllers with operator workstation (OWS) and engineering workstations (EWS) in a centralised control room, coupled to a new unified network infrastructure based on EtherNet/IP™ with Stratix managed switches. The OWS and a process automation system server (PASS) are both running in a virtual environment. Visualization was in accordance with ISA 101 while an integrated safety solution was deployed in accordance with SIL - IEC 61508/IEC61511.
Existing remote I/O from Rockwell Automation was maintained, but instead of running a Profibus network it was updated for use with Ethernet. From a security standpoint, LBC also employed the Rockwell Automation Network Security Services team to design the Ethernet infrastructure and configure the switches to conform to the network design.
By using EtherNet/IP as the primary communication protocol, LBC has given itself the opportunity to more easily move into The Connected Enterprise, an approach based on future smart manufacturing initiatives, such as Advanced Manufacturing Partnership 2.0 (United States), Industrie 4.0 (Germany), Manufacturing Intelligence 2025 (China), Manufacturing Innovation 3.0 (Korea) and others. These initiatives leverage the use of connected assets, supply chains and customers, allowing them to establish processes that are both data and information rich, supported, secure and future ready for market demands.
Benefits of access to real-time, contextualised information include minimised downtime, improved technology and process optimisation, greater workforce efficiency and smarter expenditure. Because EtherNet/IP is based on standard, unmodified Ethernet, there is very little that needs to be done to establish the connections between equipment; it also follows international standards to prevent unwarranted access.
