User Manual SUNBC-14:NE0206 39

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 ‘’ 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).
