*0
*1 This byte number is the first parameter data of first special function block.
*2 Type code of special function block is as following table. This code in the parameter must
be written first in the Lower byte and second in the higher byte.
*3 b: This value is number of BFM for adjusting.
*4 Number of exchanged BFM for input or output data (n=0 ~ 32) defines how many words
are reserved for data exchange with the DP-master. The following bytes define the BFM
addresses of those words.
For example K3 K1 K2 K5 defines 3 words of input data, read from BFM #1, BFM #2 and
BFM #5 of the corresponding special function block or written to BFM #1, BFM # 2 and
BFM #5.
*5 The format of this parameter byte is “bit 7 = write flag” and “bit 6 ~ bit 0 = BFM address”.
If “bit 7 = ON (1)”, the data of the following two bytes are written to the BFM specified in
bit 6 ~ bit 0. If bit7 = 0, the following two bytes will be ignored. This mechanism is use d to
write all parameter data from the GSD file or D200 ~ D299 to the B FM of the specia l
function block.

*6 This byte number is the last parameter data of first special function block.
*7 This byte number is the first parameter data of second special function block.
If 32DP-IF uses 4 special function blocks, user parameter must be made 4 pat terns (byt e
No. “2” ~ “5 + n + 3 × b��).
