IT Functionality 9-18

The conversion characters d, i, o, u and x may be preceded by the letter “l” to

indicate that a pointer to ‘long’ appears in the argument list rather than a ‘byte’ or

a ‘short’

The arguments that can be passed to the SSI function scanf are:

Default output:

Write succeeded

Write failed

For information about how to change the SSI Output, see “Changing SSI Output”

on page 9-21“.

Note: The I/O data is stored in the same format as it is received and sent on the

DeviceNet network. DeviceNet is a little endian protocol; values are transmitted

least significant byte first. Hence, all data in the I/O tables is assumed, by the

DeviceNet nodes, to be stored as little endian. The web server operates in a big

endian environment. Some data may have to be manipulated to account for byte

ordering when writing it from a web page.

Argument Description

OutWriteByte(offset) Writes a byte to position offset in the OUT area

OutWriteWord(offset) Writes a word (short) to position offset in the OUT

area

OutWriteLong(offset) Writes a long to position offset in the OUT area

OutWriteString(offset) Writes a string to position offset in the OUT area

OutWriteFloat(offset) Writes a floating point (float) value to position offset

in the OUT area
