Interesting,
The work that was done with apcupsd is available. I don't know if it
uses libmodbus.
APC gave a UPS with modbus support in it to the apcupsd developer who
wrote the support. My guess is that they would do the same for a
developer who added the support into NUT

Hi All,
About a month ago APC announced they were including MODBUS
protocol support in their new APC UPSes. The technical note on this
is here:
http://www.apcmedia.com/__salestools/MPAO-98KJ7F/MPAO-__98KJ7F_R0_EN.pdf
<http://www.apcmedia.com/salestools/MPAO-98KJ7F/MPAO-98KJ7F_R0_EN.pdf>
"Application Note #176 Modbus Implementation in APC Smart-UPS"
The APC "announcement" appeared on their site in their user blogs by
an APC employee, here:
http://forums.apc.com/thread/__5374?start=30&tstart=0
<http://forums.apc.com/thread/5374?start=30&tstart=0>
It states: "we have recently released a firmware update for certain
Smart-UPS SMT models (UPS 09.1)"
APC made firmware updates to their SMT UPSes for this new protocol,
which are referred to here:
http://www.schneider-electric.__us/sites/us/en/support/faq/__faq_main.page?page=content&__country=US&lang=en&id=__FA164737&redirect=true
<http://www.schneider-electric.us/sites/us/en/support/faq/faq_main.page?page=content&country=US&lang=en&id=FA164737&redirect=true>
It appears from this the affected models are:
SMT Towers with firmware >= UPS 08.0
SMT 2U Rackmount
SMT 1U Rackmount (Follow SMX <=1500VA firmware)
The announcement also appeared on the apcupsd mailing list here:
http://blog.gmane.org/gmane.__comp.sysutils.apcupsd.user/__month=20130801
<http://blog.gmane.org/gmane.comp.sysutils.apcupsd.user/month=20130801>
where it was stated that code was available.
I understand that the Socomec ITyS UPS (2000VA) UPS also uses this same
Modbus protocol.
Anyway, with all of that said, will the NUT developers be looking
into implementing this support into NUT in the future?
I'd like to say yes, since modbus support in NUT is something planned
for years.
but sadly, no.
for now, I've dumped my preliminary work and a ticket:
https://github.com/networkupstools/nut/issues/50
If someone has time + motivation + a modbus dev. (I've currently none of
these 3), I can drive him on completing this.

PS by the way - NUT allowed me to get data out of my 15 year old
Compaq R3000 UPS - I haven't got reporting data from it since NT 4
Server became obsolete. Many many thanks!
cool, I always love to hear that.
cheers,
Arnaud
