Table 4-16 Parameter formats
Format Length
(Byte)
The data type, to which the parameter is assigned, must be written into
the parameter values using the PKW mechanism.
The following apply for the format names (acc. to the recommended
PROFIBUS guideline):
Description
C4 4 Fixed–point value, 32 bit with 4 decimal places (value = number / 10 000)
Example:
P11 = 75 000 ––> 7.5 mm
I4 4 32–bit integer number (32–bit integer)
I2 2 16–bit integer number (16–bit integer)
T4 4 32–bit time constant (as for unsigned 32–bit integer)
Time as a multiple of the sampling time of 10 ms
T2 2 16–bit time constant (as for unsigned 16–bit integer)
Time is entered as a multiple of the sampling time
Speed control = 1 ms, position control = 10 ms
N2 2 Linear normalized value 200 %: 100 % 4 000 hex (16 384 dec)
E2 2 Linear fixed–point value, 16 bit with 7 binary decimal places
0 0hex, 128 4 000hex 2 V 2 Bit sequence
16 Boolean quantities combined in 2 octets
4 Communications via PROFIBUS DP
Note
All data are saved in the little Endian format (the same as for the
PROFIBUS Standard).
