TP Load

[DGrandes]

Hi,

Is there any way to register TP bus load from Logic Machine?

I want to represent TP bus load in trend log.

   

Thanks

This will give you a table with current statistics. Keep in mind that these values are cleared after reboot so trends might have a wrong value there.

Code:

stats = buslib.getstats()

Thanks!

But this table doesn´t give me " TP load". How can I get/calculate it?

Thanks

Try this (untested, so might not work) scheduled script, set to run every minute. Change 1/2/3 to object that will store current bus load (datatype is scale %).

Code:

key = 'bus-telegrams'
prev = storage.get(key)

stats = buslib.getstats()

if stats then
  curr = stats.tprx + stats.tprx

  if prev and prev < curr then
    delta = curr - prev

    -- convert to percent
    load = math.ceil(delta / 9 + 0.5)
    load = math.min(100, load)

    grp.update('1/2/3', load)
  end

  storage.set(key, curr)
end

Hi,

i don’t think this works as prev is not existing on first run, so storage will never be created..

i think you need to change it into this “prev = storage.get(key) or 0”

BR,

Hello Admin,

I would like to ask if there is a way to have a trend log of the TP load. I have tested this script but in my case didn't update the value of the virtual object (scale datatype).
I am using firmware 20180828.

Thank you in advance

Anyone got this working?
Tried it but no new values are written to the virtual object.

I have done this before. Have a look at this thread for code and info:

Please note an error in my posted script that has been corrected by admin a little down in the thread.
