about the cPCI/EPICS system of APS/LBNL

[王林 <wanglin@ihep.ac.cn>]

Hello,

I have some questions about the cPCI/EPICS system with motorola mcp750 of APS/LBNL.

In the paper "In-Situ Calibration: Migrating Control System IP Module Calibration from the Bench to the Storage Ring", it shows a cPCI/EPICS system as follows, and Labview communicates with the cpu board and uses ActiveX and SCA to interface to EPICS.

 

 

While from the paper "The Advanced Light Source Accelerator Control System At Ten Years From Commissioning" and Tech-Talk, I learn that the control system at the Advanced Light Source uses about 15 cPCI crates with mcp750 CPUs running EPICS on VxWorks, and 12 of them are used for fast orbit feedback system, which I concern with.

My question is that, What is the cPCI hardware infrastructure and the EPICS architecture of the system with mcp750 cpu board? How does EPICS on mcp750 control cPCI? Is the cPCI/EPICS system with mcp750 upgraded from the one above?

 

Thanks!
