    Hi all,
    Well, at least I have won the dummy of the week award this week :-)
    The DINTs have swapped words, so when you read from the correct address and swap the words, all is good.
    I "fixed" the publisher by creating a second publisher on same port number, and modbus address 2.
    I did have SINT and DINT data combined in the one publisher, and the PLC was making 2 read requests.
    The DINT values are now increasing as expected.

    Thanks all

    Another problem discovered. I am reading 3 x 32 bit values from an inverter via modbus, and publish them for the PLC to read. The values in mango seems correct, but are not being updated to the publisher. The PLC read is showing success, and the value in the register is being overwritten, but is is not the same as the value in Mango.

    0_1554622881993_Exported_Energy.png

    M_Exported_Energy has a value of 444315 in Mango, but the PLC shows 4390912. This value has not changed all day, so "Export Today" shows as zero.

    I checked logIO in the publisher, files are created, but no data is logged

    -rw-r--r-- 1 root root 0 Apr 7 17:09 processLog.ModbusIpPublisherRT-1.log
    -rw-r--r-- 1 root root 0 Apr 7 17:09 processLog.ModbusProcessImageSendThread-1.log
    @mango:/opt/mango/logs$

    How do I debug the publisher?

    Hi,
    I have a problem reading 32 bit unsigned ints from a PLC. The smaller values are correct, but larger values are not.
    I have done the point locater read using all the available 4 byte int types, with no luck. The data is good when read with modpoll, and agrees with the PLC data.

    The larger values are Watt hour values from power meters, and the PLC stores the midnight values, to show the current days usage.

    $ modpoll -m tcp -a 1 -r 16401 -c 18 -t 4:int -1 192.168.220.75

    The above modpoll values are correct.

    Hi,
    Just reporting that no errors in the last 24 hours,
    I have the TCP with keepalive set, Comms was very unreliable with a new connection for each request.
    Now the forest of errors has disappeared, I notice I get a "Connect timeout" twice a day, about an hour after sunset, and an hour before sunrise. I suspect a quick fix for a leaky system, as the inverter reboots twice a day.

    The inverter only accepts one modbus connection at a time, so a second device is not an option.

    The instant power value swings very quickly, as clouds move accross the sky, and the fastest update time I can get allows he PLC to adjust the load on 2 x hot water system elements via SSRs. The kWh value is only really used to display "daily usage" of 15 - 30 kWh. It could be read every 15 - 30 minutes.

    I have a support request open with solaredge, and have sent then the wireshark logs of a working modpoll connection from a PC, and a PLC connection showing only 3 x SYN request. I will sent them my findings from this, but I will ask for a "stress test" on the next inverter I purchase.

    Thanks for all your help

    Hi,
    Thanks for all the input. 247 errors yesterday (27/03/2019) on a cloudy rainy day, so the inverter does not rest :-),
    and devote more time to comms.

    The inverter is on a wired ethernet connection, with mango and the inverter on the wired LAN.

    I had "Contiguous batches only" ticked, as the inverter would not answer back when I first added it. I have now ticked it and reduced the max read registers to 50. The This is giving me 2 requests.

    What is the ,nnn after the date-time in the above log (2019/03/28-08:33:28,568). Is it mS timestamp of Java sending and receiving?

    Is there any way to have a poll period associated with a point.? The 2nd longer read is for kWh values, and could be read every 15 minutes. This might allow the instant power values to be read more frequently.

    I am using mango to read, and publish the values to a Click PLC, as I cannot get the Click to talk to the inverter. I used wireshark on the line, and I see the PLC send 3 SYN requests, and the inverter does not reply. I suspect it may be "to fast" for the inverter.

    No errors for 30 minutes, so maybe solved, but not fixed !!!!!!
    Thanks

    Hi,

    I am using Mango 3.5.6 modbus tcp to poll a solaredge inverter, and I have bursts of "No recipient" errors. For example on the 26th march, there were 240 errors, over 9 bursts. The times seem to be random, with minutes or hours between errors.

    When I first added the inverter I set the poll time to 1 second and the errors were in the thousands, but I have reduced it to the hundreds by extending the poll time to 2 seconds, and the timeout to 1500mS. This seems a long time for an TCP modbus request timeout.

    I logged the IO when I first added the inverter, and noticed there are two I or O lines together.

    Mango is also polling an Automation Direct Click PLC via modbus, and has never reported any errors.
    From the system status page

    SE5K previous sequential successful polls 	1
    SE5K last poll duration 			                        531
    SE5K poll success percentage 			        99.24194567277321

    ClickPLC last poll duration 			               63
    ClickPLC poll success percentage 		      100
    
    

    I take it the poll duration is milliseconds? Mango can ping the inverter in 0.6mS

    robert@mango:/opt/mango/logs$ ping se5k

    So my question is, is the problem / fault with Mango, or the Solaredge inverter?

    Thanks

    Hi,
    Thanks for your prompt reply.
    I restored the database , and all good now. The times on the logs were out, as I just "grep ERROR *ma.log" and cut/paste the interesting ones.

    Thanks again - Its the fastest SCADA support I have seen.

    Hi,
    I am running mango on a raspberry pi ( very well for 8 months ).
    The version is 3.5.6 and have just added a modbus ethernet publisher for a remote PLC. This worked fine for a few days. I then attempted to modify the publisher by adding another point, but did not update the register field (left it on zero) when I saved the publisher.

    The web interface lost connection.
    The top command shows java is at 100%

    Attempted a ma.sh stop and start, and the log file shows

    ERROR 2019-02-28T13:40:58,349 (com.infiniteautomation.modbus.publisher.rt.ModbusIpSlave.receivedException:189) - Publisher Slave Error

    Can I connect to the H2 database and delete the publisher ?

    Thanks

    Hi,
    Moving the /databases directory solved the problem.
    I first started mango (ma.sh start) as a user, and it appeared to start OK, but I could not login, so the database user creation must have failed !!

    After moving the database, I started with

    $sudo ./bin/ma.sh start 
    

    Connected to localhost:8080 and logged in as admin :-)

    Fedora 27, by default uses the wayland display server, which will not let root processes attach to it, if it is running as an ordinary user.
    see
    [link text](https://docs.fedoraproject.org/f27/system-administrators-guide/Wayland.html
    and
    [link text](https://ask.fedoraproject.org/en/question/97856/why-do-i-get-an-error-launching-gedit-with-sudo-in-fedora-25/

    Maybe a new option should be added to the env.properties to allow the server to start in "headless mode", so when I upgrade mango, I do not lose my "-Djava.awt.headless=true" hack

    Thanks for the prompt help

    Hi,
    Installed free-m2m2-core-3.3.0.zip on linux (Fedora 27).

    I added a line to ma.sh as mango would not start, as it was trying to connect to the x11 display.

    $ grep JAVAOPTS *.sh
    ma.sh:JAVAOPTS=" -Djava.awt.headless=true"

    I connect to http://localhost:8080 and get the mango login screen, but cannot connect as admin/admin.

    The log on the terminal screen shows

    WARN 2018-02-04T17:43:39,781 (com.serotonin.m2m2.web.mvc.spring.security.MangoAuthenticationFailureHandler.saveExceptionImpl:81) - Failed login attempt on user 'admin' from IP +0:0:0:0:0:0:0:1

    Any tips for next steps

    Thanks
