3.4.1 Activation of External Displays with „ASCII text“
For other display types or the user’s own connections (e.g. guiding system in build-
ings) any desired selection of channels can be delivered in the form of an ASCII
string with the ‘ASCII-Text’ type. Values, order, display areas and number of digits
are configurable as desired. This allows the display of extended ranges for large
scale plants.
The ASCII string will be delivered with 2400 Baud (no parity, 8 bits, 1 stopbit) at the
activated external display interface and regularly up-dated.
Example for an ASCII string:
Start Value 1 Value 2 Value 3 Value 4 Value 5 .... Ende
# LLLLLL; LLLLLL; LLLLR; LLRR; LLLLRR; CR,LF
L = Left digit of the decimal point, R = Right digit of the decimal point
Output starts with the rhombus symbol ‘#’. It is followed by the selected channel
value according to the respective format for the number of digits before and after the
decimal point (number of digits before the decimal point = total digits – digits right of
decimal point). Each channel value is finished by a semi-colon. Carriage Return (CR)
and Line Feed (LF) finish the ASCII string.
The output can be displayed and checked with any PC terminal program with the
setting ‘ASCII’ and 2400 Baud (8 N1).
