LAM 605-707109-012 VME-LTNI-S5 LonWorks Communication Board

Product Description

The 605-707109-012 (VME-LTNI-S5) is a VME form factor LonWorks communication interface board for LAM Research semiconductor plasma etch equipment. It acts as a bridge between the VME main system bus and LonWorks fieldbus subnet, responsible for bidirectional data exchange with chamber subsystems, gas modules, sensors, valves and local controllers. It transmits recipe commands and collects real-time status and fault signals, serving as a critical communication spare part for LAM etch platforms.

FAQ

Q: What does VME-LTNI-S5 stand for?
A: LTNI = LonWorks Network Interface; S5 is the hardware revision, upgraded from S3/S4 versions.

Q: What is the difference between 605-707109-002 and 605-707109-012?
A: 002 is S4 version; 012 is S5 upgraded revision with improved bus stability and fault handling.

Q: Is this board discontinued?
A: This is legacy semiconductor tool hardware, original production stopped, supplied as surplus, refurbished and tested spare parts only.

Q: Can it work independently?
A: No, it must be installed in the VME rack and cooperate with the main controller and LonWorks field devices.
