APC UPS with desktop???

[SaraCpE]

I am wondering is it possible to monitor a APC UPS from a desktop? Currently running LV 8.6, and don't know if this is possible without a battery driver since I am using a desktop. APC Power Chute works great but my employer wants to use Lab View.

Yes.  I use several APC backups and connect them to the PC with the cable they provide.  I don't install any other drivers.  Windows uses their power management utility to track the status of the UPS.  I used the located VI located here https://decibel.ni.com/content/docs/DOC-1154 to get that information into my LabVIEW program.

Hi guys!

I'm having the same problem but the thing is that I'm working with Linux, any idea is that is possible?

Thanks

You can use SNMP to communicate with an APC power supply. I have attached the SNMP library I developed years back as well as a library which communicates with an APC AP7900 PDU. Different APC units may use slightly different MIBs however they are all documented on the APC site. This should provide a basic example and a starting point.

Great thanks!

I'm going to start looking at that to see if I can use it, I let you know how it when.

Hello Mark

I'm you working on a project where I need to communicate a cRIO with a equipment using SNMP. You have some paper about the library that you have developed?, because I need to understand how to work with SNMP in LabVIEW.

[Mark_Yedinak]

I don't have a specific paper explaining SNMP in general terms. The library code I posted handles the protocol itself. You will need to know which OIDs you need need to send or retrieve from the device in order to interact with your device. It should have a MIB published which describes the OIDs, there data types and how they should be used. This MIB file is device dependent.

I am using your library to communicate with a printer RICOH by snmp, but i have a problem, when I provide a OID, the library returns the next OID's value but I need the current OID's value, What can I do to get the current OID?

[Mark_Yedinak]

It sounds like you are using the GetNext VI and not the Get one. Per SNMP, the GetNext PDU returns the value of the next OID.

Mark, thank you for answer my question!

I don't have the Get one VI. Could you send me the Get one VI?
