The
multidrop protocol
can interface several sensors via an RS-485 bus. Each read-
er has an individual address and can be addressed via different commands. For details
on this protocol we refer you to the annex (page 52).
For the serial process interface the
, the number of
and
the
can be set using the allotted input fields.
By means of the
selection field you can determine if the
rating (A-F) for the overall code quality is also transmitted via the process interface.
In this case the rating is attached immediately following the transmitted code con-
tent.
Continue to the next step of parameter setting by activating the
button or via the
button.
Configure ASCII process protocol
Continue to this dialogue when you have selected the ASCII protocol for the process
interface.
When the ASCII protocol is transmitted the code read will be embedded between a
start character string and a stop character string. Both character strings can be up to
8 ASCII characters long. Empty character strings are allowed.
You can enter the character string which is transmitted instead of the code content
in the event of failed reading into the
input field. You can input
ASCII control characters using the notation described in the reference table in the
annex (page 58).
The protocol and the process interface can be tested via the
and
buttons. The "Hello world!" character string or the
character string transmitted with
will be transmitted with the
start and stop character strings via the process interface and at the same time it will
be displayed in the output window.
Continue to the next step of parameter setting by activating the
or via the
button.
