MegaLink 2

The MegaLink 2 is a system that provides interfacing for status and demand handshake signals between Chemical Dispense Units (CDUs) and multiple Point-of-Use (POU) tools. The system provides status and valve control interfacing between Mega dispense tools and Valve Manifold Boxes (VMBs), which feed the POU process equipment by using advanced Ethernet communication. The system is designed to take control and automate factory chemical delivery, and can support up to 8 remote units per host.

In the highly configurable MegaLink 2, chemicals or slurry run from the CDU through the VMB and return to the CDU through a global loop. A signal is sent to the host when chemicals or slurry are available in the CDU. When the POU is ready for chemicals or slurry, it sends a demand signal to the host. If no alarm is present, a signal is sent to the VMB to open a single-stick automatic valve allowing chemicals or slurry to flow to the POU inlet.
