Hi Andrew,
It depends how much data you are transferring/handling of course. But I would expect any modern PC will do the job.
For example, on our beamlines here we use one Dell R200 server to talk to >10 ethernet based motor controllers, with minimal impact on CPU and memory.
I did a test a few years ago with a 2GHz Pentium 4 desktop. I connected up 12 ethernet motor controllers. Polling two of them at 20Hz (each poll reading all
8 axes), and polling the rest at 2Hz. I was seeing about 4% CPU use.
Also, Epics is designed to have small memory footprint as it runs on all sorts of embedded devices.
Cheers,
Matthew
Hi All,
I am a newbie to EPICS and I wanted to see what kind of hardware is needed to install a soft IOC. I wanted to control upto 25 LAN/ GPIB/ USB devices with more in the future.
The devices include Power supplies, oscilloscopes, Signal generators, EPICS supported other test equipment.
Will a dell computer with Red hat lInux and a few cisco network switches work for so many devices or do I need a server class computer ?
I am fairly new to EPICS and I do not know the requirements.
I will appreciate if you guys can lead me in the right direction.
Thanks,
Andrew
