Charlie,
Sorry to hear about your problems with the TS-7300 based system.
I'm using the TS-7300 with the TS-BAT3 and an industrial touch monitor
with a serial output together with a custom quadrature input board and
DeviceNet communications module.
Of the whole system the TS-BAT3 has given me the most trouble - to the
point where I might remove it from the design. All I wanted it to do
was give my system a little time to shutdown safely in the event of
power being removed while the system was running, but my confidence in
the TS-BAT3 doing this long term (3-5 Years) is not high. I may end up
using an external DC UPS which would be a shame.
I have a couple of TS-TPC-7390 touch panel systems arriving tomorrow,
which I'm intending to use in place of the industrial monitor and
TS-7300, but as they don't have a PC-104 slot I need to find a
efficient way to handle power offs. I run from the fast boot
environment, so some form of checksum on the saved files may be all
that's needed if SD card corruption can be avoided, or I'll use the
same DC UPS I use for some of my other control systems.
With regard to CAN, I don't have much experience with low level CAN -
I integrated an off-the-shelf DeviceNet interface module via RS232 for
some low speed communications. If I go with the TS-TPC-7390 I'm going
to replace the quadrature circuitry with a Luminary Micro LM3S8962
based board communicating via Ethernet. Without knowing what your
application does, would it be possible to offload the CAN to such a
co-processor (The LM3S8962 has on-chip 10/100 Ethernet and CAN) and
then communicate to it over Ethernet using UDP?
Regards,
PJE
