S7 PLCSIM - Analogue Simulation

[henno2000]

Hi, is it possible to simulate analogue values (decimal) for the PLCSIM tool in S7? If so, could someone please elaborate?

yes u can
open the plcsim press f2 and write piw 256 for example and write the decimal value u want to enter

thats one option.

You will have to write a PB or FC anyway to convert the number read from PIW xxx anyway, this is a number between 0 and 27468 (I think)
from example 0 to 10 Volts, 10 volts equals 27468

you can simulate that number in a vat table into a MW adress or so, thats how I do it

If you want your plc program to generate values for the analogue input then you will have to use a DBW or MW value instead of the PIW value in your program. (I have a simulation switch that loads either the PIW value or the simulated DBW value).

Many thanks for the advice. I have now achieved what I wanted.
