Defining Strings for Serial Ports and Viewports

8 – 13

Examples: Assume window 1 result = 1234:

This code

transmits (or displays) this field:

W1 _ _ _ _ _1234 (default format is 9 places, right justified)

W1(5) _ 1234

W1(3) 123 (result is truncated)

W1(0) (no field transmitted or displayed)

Examples: Assume formula 1 result = 123.45: *

This code

transmits (or displays) this field:

F1(5) 123.4 (result is truncated) *

F1(6) 123.45

F1 _ _123.450 (default format is 9 places, three decimal)

*Note: Decimal points (“.”), if present in the result, use one of the

allotted places in the field. If a decimal point is present, make sure you

allow for its use of one place.

(–x) The “minus” sign (– ) placed within the format code specifies the

value will be left justified within the transmitted field. Any unused places are

left as spaces following the value in the transmitted field.

Examples: Assume window 1 result = 123

This code

transmits (or displays) this field:

W1(4) _ 123

W1 _ _ _ _ _ _ 123

W1(–4) 123 _

W1(–) 123 _ _ _ _ _ _

(0x) The zero (0) placed at the left of the field width specifies that any

unused places in the transmitted field are filled with zeros. The “minus” sign

(– ) can be included to specify the value will be left justified.

Examples: Assume window 1 result = 1234

This code

transmits (or displays) this field:

W1(08) 00001234

1 2 ... 97 98 99 100 101 102 103 104 105 106 107 ... 159 160
