Pro’s and Con’s of Using New Equipment
• Total initial system cost ~ $12,500 more
• High reliability projected
• MKS 647B/C Mass Flow Control Box
– Not required, eliminating the undesirable use of
RS232 communication
• MKS GE50 Mass Flow Control Valve
– Controlled with LabVIEW directly
– Each controller has it own web server and individual
IP address for configuration
– Communicates via Ethernet
• cRIO
– Easy expansion (8 Slot Chassis)
