INT64 and FLOAT64 is Supported? #18

Closed peruchi closed 7 years ago

peruchi commented 7 years ago

Good afternoon, I'm using an equipment that has a register 64bits, INT64 and FLOAT64, and I can not capture the data, is it not supported?

v-zhuravlev commented 7 years ago

No, only 16 and 32 bits. I might add this support in the future, If you need it.

peruchi commented 7 years ago

I need to monitor the pm5340 equipment. Would you have a forecast for this implementation?

v-zhuravlev commented 7 years ago

Do you have Modbus spec for pm5340? With registers adresses?

peruchi commented 7 years ago

Yes, follow the link.

I'm trying to monitor the items:

Active Energy Delivered (Into Load) |   |   | 3204 | Wh | 4 | INT64 Active Energy Received (Out of Load) |   |   | 3208 | Wh | 4 | INT64 Active Energy Delivered + Received |   |   | 3212 | Wh | 4 | INT64 Active Energy Delivered – Received |   |   | 3216 | Wh | 4 | INT64 Reactive Energy Delivered |   |   | 3220 | VARh | 4 | INT64 Reactive Energy Received |   |   | 3224 | VARh | 4 | INT64 Reactive Energy Delivered + Received |   |   | 3228 | VARh | 4 | INT64 Reactive Energy Delivered – Received |   |   | 3232 | VARh | 4 | INT64 Apparent Energy Delivered |   |   | 3236 | VAh | 4 | INT64 Apparent Energy Received |   |   | 3240 | VAh | 4 | INT64 Apparent Energy Delivered + Received |   |   | 3244 | VAh | 4 | INT64 Apparent Energy Delivered – Received |   |   | 3248 | VAh | 4 | INT64

And this Item (Power Factor Total 3084 4Q FP PF), I had to make two minus the value received.

v-zhuravlev commented 7 years ago

You mentioned Float64?

peruchi commented 7 years ago

I mentioned Float64, however there is not a register that needs it at this point, but INT64 would be what I need. Would implementation be possible?

peruchi commented 7 years ago

Hi, this would implementation be possible?

v-zhuravlev commented 7 years ago

Yes, its possible, but can't do it right now. Will try to do it by the end of the week.

peruchi commented 7 years ago

Sorry, but would you have a prediction of when you will be able to deploy?

v-zhuravlev commented 7 years ago

Sorry! Really busy at the moment. I'll try to address your request till the end of the next week

peruchi commented 7 years ago

tks.

peruchi commented 7 years ago

Hi, this would implementation be possible?

v-zhuravlev commented 7 years ago

please test this branch: https://github.com/v-zhuravlev/libzbxmodbus/tree/int64 use datatype - S for INT64 and d for FLOAT64. In Zabbix use Numeric(float).

Also, please use modpoll utility(http://www.modbusdriver.com/modpoll.html ) and poll this first INT64 you mentioned from power meter with keys similar to this: modpoll.exe -t 3:hex -a -r 3204 -c 4 -1 127.0.0.1 see help -h for additional help on this utility

Thanks!

peruchi commented 7 years ago

Good Morning,

I tested, but not getting values.

In Zabbix: modbus_read[192.168.0.125,255,3208,3,s,1,0]

In Modpoll:

./modpoll -t 4:hex -a 255 -r 3212 -c 1 -1 192.168.0.125 modpoll 3.4 - FieldTalk(tm) Modbus(R) Master Simulator Copyright (c) 2002-2013 proconX Pty Ltd Visit http://www.modbusdriver.com for Modbus libraries and tools.

The correct value is 1.7483

Am I setting it wrong?

v-zhuravlev commented 7 years ago

in zabbix use capital S. in modpoll there is no way to poll int64, so please use hex with -c 4: ./modpoll -t 4:hex -a 255 -r 3212 -c 4 -1 192.168.0.125

v-zhuravlev commented 7 years ago

The correct value is 1.7483

I thought it is an INT64? without decimal point

peruchi commented 7 years ago

So in documentation shows

Active Energy Delivered + Received | Y |   | 3212 | Wh | 4 | INT64

But in equipament shows 1.7739

I've already checked it and that's it, but if you get only the whole value already help =

v-zhuravlev commented 7 years ago

please run modpoll with -c 4 as above

v-zhuravlev commented 7 years ago

1.7739 - is it Wh or MWh?

peruchi commented 7 years ago

at this time MWh This equipment is test

v-zhuravlev commented 7 years ago

ok try now with latest commit in int64 branch and key like so modbus_read[192.168.0.125,255,3208,4,I] in Zabbix choose Numeric(unsigned) since it appears that this counter will never be below 0.

peruchi commented 7 years ago

Now it worked but with the command you passed the error occurred:

modbus_read[{HOST.CONN},{$MODBUS_SLAVE},3212,4,I]" became not supported: Illegal function

and it worked this way:

modbus_read[{HOST.CONN},{$MODBUS_SLAVE},3212,3,S,1,1]

Can be the equipment

peruchi commented 7 years ago

Thank you for your help

v-zhuravlev commented 7 years ago

hm... how about modbus_read[{HOST.CONN},{$MODBUS_SLAVE},3212,3,I,1,1]

peruchi commented 7 years ago

It's work too.

Result: 1.88 MWh

v-zhuravlev commented 7 years ago

do you have any float64 to test?

peruchi commented 7 years ago

I have no register with float64, sorry.

v-zhuravlev commented 7 years ago

released in master branch (v0.7). Please test and report any issues.
