Hi again,

I failed to mention that for our LCLS project we have a pulsed machine.

We would need to have a way of interfacing our timing system into your

Power Supply Controllers.

If your system provides a PCI interface, this may work for our PMC-based

Event Receiver?

In terms of interlocks and such; we would also need some contact

closures and/or discrete I/O.

In any case, your interest in providing an EPICS solution "out of the

box", is excellent. :)

Thanks,
Ernest

Hello,

My company is researching providing an epics IOC with some of our

power supplies. I would like to get some feedback from the epics

community on what exactly would be required. First let me start off by

saying that epics is still a new area for me so hopefully these

questions aren't dumb, we are still in the early research stages on this.

What we would like to do is provide a system with each device that

will host an EPICS IOC. This will be a vxWorks based system running

epics base 3.14. This system will communicate with our device using

ethernet and convert standard UDP commands that our devices work on to

process variables. So for example our clients would now have a process

variable they could use to monitor or set the voltage of a power

supply (IE: powersys:voltage).

For the client side we would like to develop a LabVIEW interface, we

would most likely not be developing a custom C/C++ application for the

client.

Would this be adequate for most epics users or would more be required

to integrate this into an existing epics network? Would people use the

LabVIEW client we develop or do most labs use their own custom

software to control/monitor epics enabled equipment? Any feedback from

the community would be greatly appreciated, thank you.
