yes, people may need that point status value to control a .gif etc.
how about to feedback 0 or some special value for point value to indicate communication failed?

@phildunlap said in How to set a data point to read communication status?:

Create slave monitor points

Another question, is there a way to "Create slave monitor points" to read point communication failure? I mean if the data source communication is good, but some point failed, is that also feedback a point value that we can read?

aha, I got it, that's what I need, thank you!

How to set a data point within a datasource of Modbus TCP to read communication success or fail status, I want to use this point value.

As we know for linux server we can use nc -l port to listen HTTP packets, but how windows server to receive HTTP packets? how to scrape data value from each data point? I mean if that computer hasn't installed Mango,

understand! thanks for great support!

thanks! get it!

If there is another IoT software want to communicate with Mango, is that possible to read Mango datapoint vaule in real time ? any interface or port for that?

I installed 2.86, and I modified the file help.html which under WEB-INF\dox
but it can not show correctly in Chinese, just show error codes. how to make it to show UTF-8

I already installed "jdk-8u144-windows-x64.exe"
and then, i click "ma-start.bat"
and then, it just jam and stopped on this:

that looks great! I would like to make a try, thanks!

thank you very much! althrough there are still a lot of work and easy to make mistakes through modify codes, i prefer the old method to repeat draw and set 30x8 times, however, if there are 100 houses x 30 sensors or 1000 house will be a huge workload.

for example, there is a 8 room house, each room have a temperature sensor, so I put 8 analog points on the photo. But the whole building has 30 sets of such houses with the same layout. so I do not want to upload the same picture 30 times and put those analog points on each photo one by one manually for repeat 30 times.
so I hope they can share the same layout photo and analog points, and when i click link "house01", the background layout photo do not change, but the analog points' value switch to show house01's temperature, and when i click link "house02", the background layout photo do not change, but those points' value automatically change to show house02's, and so on. how to handle this?

@mothgo990 : what i mean is i have many machines(PLC) use the same photo, i do not want to prepare and modify 100 photoes for 100 machines.

how to change points automatically without change background photo? i wanto make a drop menu for selection, when i select number01 then point change to show the value of "PLC01 - temperature", when i select drop menu number02 the data shows on photo can be automatically change to "PLC02 - temperature" value, etc.
