Tab. 3/10: Configuration parameter Format
Two words are used when a controller with an address
range > 65536 is used. A conversion into hexadecimal values
is required; see following example:
245987 = 0x3C0E3
Byte 4.5 (FHPP): 0xC0E3
Byte 6.7 (FHPP): 0x0003
Conversion is not necessary when a higher−level fieldbus
master and double words are used.
If a Profibus control is used, attention must be paid that the
bytes are correctly transferred. The bytes might be
transposed.
Significance
If a 16−bit controller is used, e.g. CPX−FEC:
for MTR−DCI and SFC−xx, the position
value is first converted into [ m] or
[1/1000°] and then into before decimal
word (BD) and after decimal word (AD).
