I created with logo soft comfort a ladder program which uses
some initial parameters (running times of motors) introduced
as V1 in an arithmetics instructions

The aim is the operator to be able to modify the parameters
in a webpage and I do not want the parameter will be a zero
or lost in the event of a power cut.

the problem is that this number is displayed in a analogic
block value as an output  in webpage but I don't know
how to write it like an input to modify the previous parameter

​thanks for your help

I upload the zip file of the page 1 of LSC program and an

abstract of the LWE page.

(PS the analog slider will be used to make the balance between
two reagents A and B.)

many thanks.

thank you very much for your help.

If I have understood correctly :

Analogic parameters (analog bar, slider, value...)

that will have to be overwrited by the user,

need to be set in a mathematical instruction via mapping.
