Xantrex XW6048 inverter keeps on going offline and online in Data Center Expert causing so many Communication Lost alerts. It continuously goes online for about 5 min then goes offline for 1 minute. Readings are distorted because of this. The readings have to be in real time and available when they are needed.
There are 2 Conext XW 8548 E inverters connected using Xanbus through the Combox. Below is the details of the Conext Combox partnumber 865-1058.

Dear Cleopas Chisambiro,
Regarding your problem:
Q1: Are your two inverters connected via two serial lines to the same Conext Combox?
Q2: Is the connection lost for only one of the two inverters or for both?
Q3: The lost of communication began after what events, how long (approximately)?
Q4: What version of DCE software do you have and what version of the DDF-file is used to poll two inverters through Conext Combox device?
Q5: Have you tried to find or view in any way the quality of communication over serial lines between your Conext Combox device and your two inverters? Maybe there are a lot of CRC errors, timeouts, protocol errors?
The more you provide useful information, the faster and better you will be helped here 😀.
With respect.

Q1: Yes both are connected to the same Combox using Xanbus
Q2: It is coming from both inverters and sometimes they interchangeably loose connection
Q3: Everything will be fine the after about 5 min the inverters looses connection for about a minute
Q4: Initially there was version 7.2.7 and we upgraded to 7.5.0 thinking the issue would be resolved. I am not sure about the DDF version, its on http://sxwhelpcenter.ecostruxureit.com/devices/view.action?deviceId=Xantrex+XW6048-230-50&vendorId=S...
Q5: If I log into the Combox while it is offline it shows all the data from the inverters including the voltages in real time.

Dear Cleopas Chisambiro,
Q3: I wanted to know if this connection problem was from the very beginning of connecting your two inverters to DCE software, or was everything normal for a long time (month, year, etc.)? And just recently there was this connection problem?
Q4: Can you clarify the name and version of the DDF-file you use, which you downloaded from the Device Support resource and imported into the DCE software? Can you show a screenshot of the DCE software with a complete list of your Modbus DDF-files?
With respect.

Q3: From the start it was like this. There was no change for better or for worse.
Q4: I'm not sure about the version of the DDF but the name is schneiderelectric_xantrexxw604823050

Dear Cleopas Chisambiro,
Q3: Ok, then you should first try to increase the Modbus timeouts slightly when polling your problematic inverter devices. For example, as shown in my screenshot:
Q4: What is the version of this DDF-file? After all, you can find out this information exactly in the DCE-client.
I want to note, that it is not possible to download the DDF-file for your inverter device from the Device Support resource. It is very strange... Therefore, I asked you for exact information and necessary screenshots.

Q3: I have tried that one before, I set Timeout to 60sec and reties to 5, what can be the best values.
Q4: From Device Definition Files it is written version 1, you can check from the images I sent which is named "DDF files"

Dear Cleopas Chisambiro,
Q3: In this case, you should definitely check the serial line comm settings on your Conext Combox. It is also necessary to see, if possible, the quality of data transmission over a serial line. The problem may not be in DCE software, but in the correctness of the serial comm settings of your Conext Combox.
Q4: But I do not see you showing any images...
With respect.

Q3: It uses an RJ45 port and an ordinary cat6a cable with a terminating resistor at the end. Everything looks fine in the Combox because it has a GUI with real-time value. I will check if there are ways to check errors in the serial communication.

Dear Cleopas Chisambiro,
Ok, thanks for the screenshot. I will wait for further information about the serial lines comm settings of your devices.
With respect.

Dear Cleopas Chisambiro,
I have already received the above Modbus DDF-file and I will wait for news from you on this issue.
With respect.
