Hi

more general question - does anyone noticed higher memory usage and CPU load when using this Modbus binding?

I use ModBus TCP with “miniITX AMD E-350 8Gb of RAM”
:~$ ps -C java -o %cpu,%mem,cmd
%CPU %MEM CMD
130 11.4 /usr/bin/java -Dopenhab.home=/usr/share/openhab2 -Dopenhab.conf=/etc/openhab2 -Dopenhab.runtime=/usr/share/openhab2/runtime -Dopenhab.userdata=/var/lib/openhab2 -Dopenhab.logdir=/var/log/
:~$


(Ssalonen) #264

As the docs say: length is

Number of registers, coils or discrete inputs to read.

So if you want to read single 32 bit number (e.g. float32), you need to read two registers (length=2). For 16 bit number (e.g. Uint16) single register (length=1) is enough.


(Antanas) #265

Thanks.

another interesting thing: installed EXEC Binding and now cannot connect to ModBus:
2018-01-10 20:27:54.213 [WARN ] [rt.modbus.internal.ModbusManagerImpl] - Try 1 out of 3 failed when executing request (ModbusPollerThingHandlerImpl.ModbusPollerReadRequest@c6648e8[slaveId=2,functionCode=READ_MULTIPLE_REGISTERS,start=0,length=5,maxTries=3]). Will try again soon. Error was: net.wimpi.modbus.ModbusSlaveException Error Code = 6 [operation ID 5d8e25e8-f361-4c7e-8c53-03983e819cea]

p.s. it was working for a week or so no without a problem.

Does the error code=6 is general modbus tcp ‘thing’ or something special with this binding?
thanks


(Ssalonen) #266

That is part of modbus protocol, not specific to this binding. Error 6 comes from the slave device. You can find explanations here

http://simplymodbus.ca/exceptions.htm

Specialized use in conjunction with programming commands.
The slave is engaged in processing a long-duration program command. The master should retransmit the message later when the slave is free…

Best
Sami


(Antanas) #267

Thanks Sami!
Need to debug for what my unit is doing at that moment.

(Andreas) #268

I have modbus-binding up and running. But I have no glue how I can transform a integer to boolean using transform.js. I read the value 32769 witch means door closed or 32768 witch means door open. Is there a way to transform this using transform.js? thanks for any hint what I had to search for …


(Ssalonen) #269

I assume you mean contact or switch item with boolean. There is no general boolean type as far as I know.

Since there are just two values (32768 and 32769), the map transformation might be the most straight forward: https://docs.openhab.org/addons/transformations/map/readme.html

You can examples from modbus binding documentation that use transformation. Instead of JS(…) you would have MAP(…) as the transformation.


(Antanas) #270

@ssalonen, could you please advice what might impact ‘strange’ behavior of the binding?
When I try to change item status (i.e. lower vent unit power) I’m switching the status, meaning writing to a registry different value.
The strange thing is that I see my item is switching back and forth few times:
2018-01-11 14:35:53.475 [ome.event.ItemCommandEvent] - Item ‘komfoCurrentModeWrite’ received command 1
2018-01-11 14:35:53.481 [vent.ItemStateChangedEvent] - komfoCurrentModeWrite changed from 2 to 1

2018-01-11 14:36:01.184 [vent.ItemStateChangedEvent] - komfoCurrentModeWrite changed from 2 to 1

meantime openhab.log shows:

}

items:
/* Control */
Number komfoCurrentMode “[MAP(komfoOperationModes.map):%s]” { channel=“modbus:data:HVAC:CurrentMode:komfoCurrentMode:number” }
Number komfoCurrentModeWrite “[%s]” { channel=“modbus:data:HVAC:CurrentModeWrite:komfoCurrentModeWrite:number” }

sitemap:
Frame label=“Control” item=komfoCurrentMode
Selection item=komfoCurrentModeWrite label=“Operation Mode Select” icon=“rgb” mappings=[0=Null, 1=Away, 2=Normal, 3=Intensive, 4=Boost]

What I’m missing here or why this might be happening?

thx


(Ssalonen) #271

Hi @ArC!

It’s a bit hard to read the logs, could you please format all configuration and logs using code formatting: Auto highlighting/formatting on code blocks in posts

Also, it looks like the openhab.log is not from the correct time (ends at 14:35:46, while the events are from 14:35:53) so there’s not much to go on…

This is just a wild guess (correct logs would help!) Please understand that openHAB automatically changes the state of the item when command is received by an item. You can disable this behaviour using autoupdate parameter, refer to openHAB docs: https://docs.openhab.org/configuration/items.html#exception-autoupdate

This could partly explain what’s going on:

Item ‘komfoCurrentModeWrite’ received command 1
komfoCurrentModeWrite changed from 2 to 1  // changed by openhab, since command was received
komfoCurrentModeWrite changed from 1 to 2  // polled value from modbus? (command did not yet have an impact)
komfoCurrentModeWrite changed from 2 to 1  // polled value from modbus updated to new  value?
komfoCurrentModeWrite changed from 1 to 2 // ??
komfoCurrentModeWrite changed from 2 to 1 // ??

Looking at the correct logs tells exactly what is polled from the slave.

Best,
Sami

EDIT: also interested to hear more about the CPU usage. How much does it increase with the modbus binding? Do you have stats with 1.x binding?


(Ssalonen) #272

@narf27 hmm I think you are right :frowning: modpoll does not work with raspi and mbpoll only supports TCP slaves…

Not sure what to advice. We have seen slaves that do not answer to some specific requests, perhaps this is similar case. Can you read in two parts (two registers + two registers)?

Is there anything in device documentation regarding some limitations with respect to requests?

Edit : realized you previously used the old binding (successfully?) to read values. Please ensure that the serial port parameters are correct. I am curious if you find a case which worked before but anymore.

EDIT2: @narf27 here are two examples using python libraries pymodbus and minimalmodbus

These should work with python 2.7 or higher. The only trick is to install dependencies for these scripts (pymodbus or minimalmodbus). Hope you get the idea and adjust the scripts accordingly.

test_pymodbus.py:

# Installation
# - install dependencies:
#       pip install pymodbus six
#     or 
#       easy_install pymodbus six
# Running script:
#      python test_pymodbus.py

from pymodbus.client.sync import ModbusSerialClient

# https://github.com/riptideio/pymodbus/blob/master/pymodbus/constants.py
port = '/dev/pts/3'
baudrate = 38400
stopbits = 1
bytesize = 8
parity = 'N'  # 'E', 'O' or 'N'


address = 0
count = 5
unit = 1



slave = ModbusSerialClient(method='rtu', 
                           port=port, 
                           baudrate=baudrate, 
                           stopbits=stopbits, 
                           bytesize=bytesize, 
                           parity=parity)
out = slave.read_holding_registers(address, count, unit=unit)
 
print('%s: %s' % (out, out.registers))

test_minimalmodbus.py:


# Installation
# - install dependencies:
#       pip install minimalmodbus
#     or 
#       easy_install minimalmodbus
# Running script:
#      python test_minimalmodbus.py

import minimalmodbus
import serial

unit = 1
address = 24
count = 1

port = '/dev/pts/3'
baudrate = 38400
stopbits = 1
bytesize = 8
parity = serial.PARITY_NONE


slave = minimalmodbus.Instrument(port, unit)

slave.serial.port          # this is the serial port name
slave.serial.baudrate = baudrate   # Baud
slave.serial.bytesize = bytesize
slave.serial.parity   = parity
slave.serial.stopbits = stopbits

print(slave.read_register(address, count))

There are others as well, e.g. https://github.com/favalex/modbus-cli (assumes parity=none)


(Peter) #273

meaning? =)
this:

    Bridge1 poller inputRegisters [ start=200, length=2, refresh=1000, type="input" ] {
        Thing data input1 [ readStart="200", readValueType="int32" ]

    Bridge2 poller inputRegisters [ start=202, length=2, refresh=1000, type="input" ] {
        Thing data input2 [ readStart="202", readValueType="int32" ]

instead of this:

    Bridge poller inputRegisters [ start=200, length=4, refresh=1000, type="input" ] {
        Thing data input1 [ readStart="200", readValueType="int32" ]
        Thing data input2 [ readStart="202", readValueType="int32" ]

?

cheers
Peter

Hi,
thanks for the hint as to how format the log correctly, apologies, I’ve not used much forum before.
Yesterday played a little bit with various options and must say cannot re-produce the same behavior again :frowning:

What I did is: restarted openhab itself in the first place, then added autoupdate value next to the item, enabled TRACE option in karaf:

openhab> log:set TRACE org.openhab.binding.modbus
openhab> log:set TRACE org.openhab.io.transport.modbus
openhab> log:set TRACE net.wimpi.modbus

So I paste here the log output (matching the time-stamp, thanks @ssalonen! ) as what I can see (sorry if that’s a longer trail than expected):

Today I’ve changed poller to be various numbers, a mix, and can see less cpu/mem usage overall:

Tasks: 193 total,   1 running, 192 sleeping,   0 stopped,   0 zombie
%Cpu(s): 46.8 us,  6.6 sy,  0.0 ni, 45.9 id,  0.5 wa,  0.0 hi,  0.2 si,  0.0 st
KiB Mem :  7767316 total,  3406784 free,  1120244 used,  3240288 buff/cache
KiB Swap:  7973884 total,  7973884 free,        0 used.  6217528 avail Mem

Seems like if I try to poll my slave very frequently - it becomes a “hard” task :slight_smile:

The only remaining thing to work out left is - how to ensure stable connectivity, as I see time to time unsuccessful connections:

2018-01-12 11:39:25.794 [WARN ] [rt.modbus.internal.ModbusManagerImpl] - Try 1 out of 3 failed when executing request (ModbusPollerThingHandlerImpl.ModbusPollerReadRequest@748793f[slaveId=254,functionCode=READ_MULTIPLE_REGISTERS,start=4,length=1,maxTries=3]). Will try again soon. Error was: net.wimpi.modbus.ModbusSlaveException Error Code = 6 [operation ID b79dba2d-c16d-407d-81d3-8cbaea985657]

thing:

(Hallo Ween) #275

I have an eastron sdm630 powermeter with modbus.

Is there a way to get the modbus data out of the meter using for example an esp8266 ?

Then send the modbus data with wifi.

And openhab will get the modbus data over network-connection.

So can i use your binding to read out the data?

Anybody knows how to do this?


(Antanas) #276

Hi @halloween,

yes, you can achieve that. As long there is a nice write up for your powermeter [http://www.eastrongroup.com/data/uploads/Eastron_SDM630-Modbus_protocol_V1_5.pdf] and you can check i.e. [http://fab.cba.mit.edu/classes/863.14/tutorials/Programming/serialwifi.html] for Serial-to-Wifi communication example.

Once you get there - Modbus binding will be pretty straight forward to read/write data by Openhab.

regards


(Ssalonen) #277

Yes @narf27, that is correct.


(Ssalonen) #278

@ArC Thanks for the reply. Let me know if the issue happens again.

If I understand correctly, the cpu load is quite moderate (below 5%)?

The error 6 is interesting. Does it work when the binding retries (in your log try 1/3 fails but does the second try work?)?

Best
Sami


(Antanas) #279

@ssalonen, yes, CPU looks ok now.
Since I put connectMaxTries=3 I only see the message once:

2018-01-12 14:35:13.710 [WARN ] [rt.modbus.internal.ModbusManagerImpl] - Try 1 out of 3 failed when executing request (ModbusPollerThingHandlerImpl.ModbusPollerReadRequest@313519cd[slaveId=254,functionCode=READ_MULTIPLE_REGISTERS,start=99,length=24,maxTries=3]). Will try again soon. Error was: net.wimpi.modbus.ModbusSlaveException Error Code = 6 [operation ID ab422011-157f-4673-b9a4-e980c703068a]

do not see 2/3 or 3/3 as an error/warn and the values seems being updated afterwards. So my only guess is that I’m lucky that trying to poll data at the same time when the unit is doing something etc, who knows.

and the error of 6 (advised by you earlier) shows that the slave is busy at that moment.

Regards

I have to read holding registers from a wide range of addresses. For that reason I had defined a couple of holding pollers. But only the first holding-poller is working. Dos I have to create for every holding-poller a new *.things-file?

Ready made converters are available for RS485 or RS232 Modbus-RTU to Modbus-TCP over WiFi

There is no need to split to many things files, as far as I know. What do you mean by “not working”?
