At DESY we are using the TIP810 and a compatible IP module built by IHEP
in Russia.

In addition we are using DIN Rail PC's with a built in CAN interface
based on the Intel 82527 chip.

All of them with EPICS support based on Andrews IPAC driver with our CAN
driver below.

Bill,
At APS we've just moved to VIPC626 IP carriers. These are software
compatible with the previous VIPC616 model which has EPICS support.
The VIPC626 are a lot easier to configure I believe, no wire wrapping
required.
I've used the TIP810 modules with Andrew Johnsons driver code on a
couple of projects and have found them to be absolutely rock solid.
IIRC they use an early generation of CAN controller chip. Later
generations of CAN controller mainly do more to offload processing
from CPU. This is probably not an issue unless you have many heavily
loaded CAN links coming into your ioc. I don't think 3 will be a
problem, but it will depend on the amount of bus traffic you have of
course. Gemini have 8 buses in one ioc. It almost certainly isn't an
issue if you use a PPC.
HTH,
John.

Greetings,
I am trying to duplicate a CANbus system here at the STAR experiment.
We have

two distinct modules/controllers and chains. We want to split off
some Wiener

crates to form a third (to make life easier on some subsytem
detectors). It

would also give us a backup option!
We presently have two GreenSpring TIP810, which are VIP610 carrier
boards. (6U

VME boards with 4IP and front I/O ribbon connections). We use two
processors,

one is a 162, and the other 167, otherwise things are pretty
identical, except

for the numbers and kinds of Wiener crates on each chain. For these
systems we

run an old version of VxWorks 5.2 and an old version of EPICS 3.12-LBL.4

I did get some information from TEWs regarding the TIP810-10 which
replaces the Greenspring 810, and am anxious to order. I wanted to
get some expert advice

first.
Would there be significant benefits to trying a "new" approach rather
than

duplicate. This all seems like a quick and easy option but perhaps
there are

others that we should be considering? (For example other carrier
boards, the

TIP816 etc.)
Thanks in advance
