Hello,

I have a similar issue.

  1. the link https://github.com/PLCnext/HTML5_with_REST is not accessible any more.
  2. Is the way explained in the August 2019 still the best way?
    Because I have to plot historical data that I would save with the datalogger feature.
    So instead of REST API I would use SQlite or OPC UA library in JS.
    Any other way?
    Maybe a eHMI object in the next release as indicated in https://www.plcnext-community.net/en/discussions-2-offcanvas/trend.html

Thanks,

M256

Dear M256,

sorry for the late reply, but at least I have good news.

With FW 2021.0LTS (just released for AXC F 1152/2152) we've introduced an TSDB which can be used for the integrated real-time datalogger.
In combination with the brand new "chart" object in PLCnext Engineer 2021.0LTS you have now a very easy way to visualise the historicals inside a PLCnext HMI application.

Just follow the introduction in the PLCnext Engineer Help, just search for "chart".

Take care,

Frank

Hello M256,

 

have a look here for the REST api documentation.
I will inquire about the state of the eHMI object and update you on that asap.
kind regards,
Oliver
