Hello Arijit, =20
=20
I connected an S7-300 to my PC, downloaded myself version 0.0.21 to have t=
he exact =20
code, and, very sorry, I must tell you we have now TWO problems: =20
=20
The first ist that your adapter sends NAK, according to the last log file.=
=20
That may be different after a reset or with another adapter or with change=
s in the =20
drivers initialization code. =20
=20
But the second problem is the s7MPI driver doesn=B4t even work on my box wit=
h my adapter. =20
The problem is I changed a function comparing responses to a given byte pa=
ttern so it =20
can deal with bytes marked don=B4t care in the middle of a sequnce. This was=
to handle =20
slight differences more easily. But I did not test the code before releasi=
ng it -:( =20
=20
The second is I introduced a method to reload the driver=B4s tfi on a signal=
. =20
Again, this doesn=B4t work with s7MPI. =20
=20
Both problems arose from mixing different code versions. =20
=20
Nearly 1000 people have it downloaded since, but nobody has ever reported =
this... =20
=20
Exchange the attached files as a preliminary hot fix. Both files go to dri=
vers=20
directory.=20
=20
A third little thing is, the s7mpi.tfi doesn=B4t fit the sheet 1 in work. Th=
e problem is=20
the tfi wants to get the execution condition from A1, which is a text. So =
It exits with=20
nothing to do, and repeats this so fast that it generates 45M of log file =
in a few=20
seconds. To avaoid this, insert some number, e.g. 1.0 into cell A1 of the =
first sheet.=20
=20
=20
I will send final fixes as soon as possible. =20
