an error message when closing the dialogue. The values entered will then not
be saved.
l
Timeout
Sets the maximum permissible time between a request and a response
before an error status is shown. In the event of an error, a "wire break"
status is displayed according to the number of timeouts set with
Produce
wire break after
. The time must
be short enough in relation to the time for the
Poll cycle
or you will receive an
error message when closing the dialogue. The values entered will then not be
saved.
l
Pause
Sets the waiting time for a query from more than one channel within a poll
cycle. The time must be short enough for all channels to be queried within
the time entered under
Poll cycle
or you will receive an error message when
closing the dialogue. The values entered will then not be saved.
Poll string
Enter here a character string for all output channels which is to be output
and which prompts the user to send its data if this is required. If you
require data from several channels with different poll strings, do not
enable the option here, but enter instead the poll string separately for each
relevant input channel.
Enter the string as text. ASCII characters that cannot be entered directly,
e.g. carriage return (CR) or line feed (LF), can be entered using % and the
ASCII value in hexadecimal format: Enter CR as %0D and LF as %0A.
Termination
This setting applies to input and output channels for the interface and can-
not be changed for a specific channel. The entries for
termination symbol
and
transmission pause
are, however, used simultaneously. For example,
an input message is considered ended after either the
Termination sym-
bol
and/or a pause larger than the time given in
transmission pause
.
l
Termination symbol
One or more ASCII characters that indicate the end of a message. If the char-
acters cannot be sent, or if you do not enter any characters, the
transmission
pause
will be used for end recognition.
Enter the characters as text. ASCII characters that cannot be entered dir-
ectly, e.g. carriage return (CR) or line feed (LF), can be entered using % and
the ASCII value in hexadecimal format: Enter CR as %0D and LF as %0A.
You can enter only one end sequence. Multiple end sequences are not pos-
sible.
