Integration object from ETS - Tokatubs - 01.12.2018

I am integrating some GDB181 Vavs from SIEMENS. To write the Vmin and Vmax the value is written in % and the object is 08.010 percentage difference.
Lets say for example value is 15% in Vmin of the Vnom.

But when the value comes to the Lm5 its a 2 byte signed integer and the value is 1500. Whats the correct way to get this corrected?

You can make the conversion via a script. Create a virtual object via 4 byte floating point data type. Use this object for control/display.

In this example source 2 byte object is 1/1/1 and virtual object is 32/1/1. Change as needed.

Attach an event script to virtual object (32/1/1):

Code:
-- do nothing if triggered by another event script

if event.sender ~= 'se' then

  value = event.getvalue()

  grp.write('1/1/1', value * 100)

end

Then attach another event script to source object (1/1/1):

Code:
-- do nothing if triggered by another event script

if event.sender ~= 'se' then

  value = event.getvalue()

  grp.write('32/1/1', value / 100)

end
