ALS control system IP I/O module upgrade

PDF Version Also Available for Download.

Description

The Control System for the Advanced Light Source uses in-house designed IndustryPack (IP) I/O Modules in compact PCI (cPCI) chassis to control instrumentation. Each module consists of digital I/O ports and 16-bit analog I/O interfaced to instrumentation via a cPCI rear I/O card. During the past few years of installed operation, several factors have prompted investigation into the design of a new IP I/O Module. The ADC channels have significant offset drift over periods of days of initial installed operation. An in-situ calibration procedure was developed to address this problem, but it lacks speed and is inconvenient to perform. Digital ... continued below

Description

The Control System for the Advanced Light Source uses in-house designed IndustryPack (IP) I/O Modules in compact PCI (cPCI) chassis to control instrumentation. Each module consists of digital I/O ports and 16-bit analog I/O interfaced to instrumentation via a cPCI rear I/O card. During the past few years of installed operation, several factors have prompted investigation into the design of a new IP I/O Module. The ADC channels have significant offset drift over periods of days of initial installed operation. An in-situ calibration procedure was developed to address this problem, but it lacks speed and is inconvenient to perform. Digital I/O port limitations have led to increasing amounts of wasted I/O. Fast orbit feedback requires faster ADC sampling and better filtering than the current IP module offers. This paper discusses the issues related to the current IP I/O Module and the design of a new Double-size IP I/O Module.
