CAEN SY 1527 Hardware Configuration
CAEN SY x527 EPICS Driver from Canadian Light Source
We sent an e-mail to Ru Igarashi asking him for his EPICS driver for SYx527 CAEN HV chassis. He sent us a tar ball with what he currently had, plus a User's Guide. It is not clear how much effort Ru will be putting into this project. He says that:
- It is not a full implementation of the available controls, lacking crate-wide and board-wide control.
- I haven't had time to eliminate a bug that causes the controls to lose communication with the crate
It is also apparent that some of the functionalities that were implemented need improvements, some of the parameters are hardcoded in the source files. So, if we want to use this driver, we will need to evaluate it, identify the problems, fixed them and add more control features. like board and crate-wide functions.
We took Ru's tar-file and adopted his source code and his EPICS database to our current EPICS scheme. We also used his EDM screens to evaluate the driver for the first time (automatic conversion to BOY OPI failed). The driver connected to our test SY1527 chassis and the EPICS records seemed to work. On driver initialization we get a lot of messages
CAENHVGetCHParamProp(): Param Not Found (22), but otherwise the application seems to work fine.
