Hi! I was wonering if there is a driver that supports communicating with a Modbus aware device over IP. I have a solar/wind invertor that can broadcast its state and I would like to monitor the batteries. If they discarge to a certain voltage or come to a defined state, I would perform a shutdown. All of this information id provided in Modbus holding registers. This could of cou...

Yeah, I have its datasheet (it's a Xantrex XW invertor by the way). I do not know why creating a more-or-less generic driver is an issue. Of course, there are Modbus beasts that can scare everyone but mostly one would need to read either intreger or float numbers out of Modbus registers in order to decide whether or not to start or stop the shutdown process. 24 ???? 2017 ?. 19:25:14 GMT+03:00, Charles Lepple <clepple at gmail.com> ?????: >On Jun 24, 2...

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 "Application Note #176 Modbus Implementation in APC Smart-UPS" The APC "announcement" appeared on their site in their user blog...

Hello, this is to let you know I will start working on a modbus driver for the PhoenixContact QUINT-UPS industrial DC UPS, model 2320461. https://www.phoenixcontact.com/online/portal/us?uri=pxc-oc-itemdetail:pid=2320461&library=usen&pcck=P-22-07-01-01&tab=1 I will reuse some parts of the nutdrv-modbus branch, but this will be a model specific dri...

...lo all, During holiday revision of issues (hoping to tie up loose ends and get to NUT v2.8.1 soonish), an old https://github.com/networkupstools/nut/issues/50 ticket came to my attention - that some years ago "we" (as NUT community) wanted to create an unified driver for devices with a Modbus connection -- similar to `nutdrv_qx` doing everything about Megatec Qx protocol family (USB/Serial), `snmp-ups` or `usbhid-ups` with subdrivers for vendor nuances over a common playground... In the end what happened over the past years was that several independent drivers were made or proposed f...

Hi, does anyone have any experience with UPSes managed with modbus/jbus protocol? I have a Socomec/Sicom Masterys MC unit, that is equipped with both RS232 and RS485 interfaces and, according to manual, supports JBUS-P and JBUS-PH protocols. I'd like to get some basic monitoring working, but I don't even know where to begin. Regards, -- Sebastian Zagrodz...

That is not true. The MODBUS protocol has been documented by APC and the open source apcupsd program supports it. The proprietary protocol APC uses is yet another protocol they call microlink. And the UPSLink protocol that NUT...

...e blazer_ser driver to interface with my UPS. nut is not able to detect the UPS. I have not been able to find much info regarding Socomec UPS support in nut. Socomec does publish a description of the serial protocol for these UPS's, which can be found here: http://www.socomec.com/download-jbus-modbus.html(select UPS OTHER for device model, 1-5KVA for device power and Linux for the operating system) This is all the info I have managed to find about the serial protocol for these UPS's. How much work is involved to patch an existing driver or to build a new one? I am not a programmer, so I no...

I think the time for me to get involved in NUT documentation has come again. Late last week I had to buy a UPS under time pressure. The Eaton unit that thus project gifted me with in 2006(?) died during a severe thunderstorm watch, so it was off to MicroCenter to get a replacement pronto. I wound up buying an APC BN700MC. It was what they had in the performance range I needed. The removable

...I just realize that I can't retrieve the ups.load, among other > thing :-( To the best of my knowledge, Microlink is not supported by any third-party tools (including NUT), but some variables are exposed via standard USB HID. Apparently, ups.load is not one of them. Your UPS might support MODBUS: http://lists.alioth.debian.org/pipermail/nut-upsdev/2014-July/006769.html but we need developers to help add MODBUS support to NUT. Alternatively, you can use apcupsd: http://apcupsd.cvs.sourceforge.net/viewvc/apcupsd/apcupsd/ReleaseNotes?pathrev=Release-3_14_11 and if you need connecti...
