Festo delivered 200 ready-to-install stainless steel control cabinets for the roughly 80 batching tanks and bioreactors at the new biotech plant which has in the region of 5000 valve functions. The different-size control cabinets house the modular CPX/MPA valve terminals with between 24 and 128 valves and can be integrated into the Yokogawa Centum control system.
“From our perspective, standardization has big advantages. Equipment maintenance is less complex. Spare parts requirements are lower, less effort is needed to train the service team and we have a single point of contact for the pneumatic systems," said Kelly. That applies to the engineering and installation phase of the project, but even more so to the operational phase. Studies show that repair and maintenance costs over the full lifecycle are often significantly higher than the original investment.
The CPX/MPA valve terminal is the central piece of automation equipment at the actuator/sensor level. All signals and process valves which are not Fieldbus Foundation enabled are connected to this highly versatile control system which acts as an I/O device under bus control.
