Some history of our SNMP driver:
I wrote a modification of the DESY SNMP driver when we got our first
Wiener/ISEG/MPOD crate a few years back, just to add write support. I
then undertook a much bigger re-write to give sets priority over reads
in the transaction queues, as our operators were complaining about how
unresponsive tuning was. I was unaware of Sheng Peng's version at the
time or perhaps I would have started with that. I haven't dug into it
to see what it does about prioritization.
At the moment we've got 7 MPOD crates we're using our NSCL/FRIB driver
with but none are officially "production", they're in beamlines under
development but they get a decent amount of use with some actual beam.
I'm always happy to hear how it's working for others!

I looked at the various SNMP EPICS support modules when we received some Wiener VME crates a couple of months ago and decided that the MSU package from John Priller looked the best for documentation, capabilities and recent support. I added a few minor changes and it's working well for us now. The most important change is one that provides a mechanism for long OID strings in INP/OUT fields. These changes have been folded into the distribution (version 1.0RC6).

Dear all,
for our low voltage power supply, we are thinking about using the Wiener MPod which is controlled via SNMP.
From Wiener I know that there are some implementations for EPICS:
- The original devSNMP from DESY
http://www-mks2.desy.de/content/e4/e40/e41/e12212/index_ger.html
- An extension of the first one from John Priller
http://groups.nscl.msu.edu/controls/
- and a third one from Sheng Peng from Diamond light source
http://controls.diamond.ac.uk/downloads/misc/snmp.tgz
Is there any great difference in those device supports? Especially between the second and third one?
Are there any recommendation which one to use?
Best regards,
Florian
