SIMOREG DC Master Operating Instructions
Modify parameter U099.001 using SET Single (for details in the shaded data area, see also
Section 7, Starting up PROFIBUS boards):

Request identifier = 7063h (modify parameter value (array) U099), index = 0001h = 1d (bit 15 is
also set in the H byte in order to address the parameter number range from 2000 to 4000), value =
00C8h = 200d
Response by SIMOREG:
Byte DeviceNet identification
1 [FRAG] [XID] [SRC/DST MAC ID]
2 [R/R] [Service] 0x90 [Set_Attribute_Single]
3 0x63 Parameter ID, L byte
4
PKE
0x40 Parameter ID, H byte
5 0xC8 Parameter value, L word, L byte
6
PWE1
0x00 Parameter value, L word, H byte
7 0x00 Parameter value, H word, L byte
8
PWE2
0x00 Parameter value, H word, H byte
Response identifier = 0x4063, value of U099.001 = 00C8h = 200d (PWE2 remains unused
because SIMOREG 6RA70 has no double word parameters)
Information about PKW transmission:
The length of a request from the master is two words (for GET Single) or 4 words (SET Single).
The length of a SIMOREG response is always 3 words.
The low-order byte or word is always sent before the high-order byte or word.
The master may generate a new PKW request only after it has received a response from the slave
to the previous request.
The master identifies the response to the transmitted request by
evaluating the response identifier
evaluating the parameter number
evaluating the parameter value (if further identification is needed)
The CBD slave does not respond to a parameter request until it has received the relevant data
from the drive. The time delay depends on the type of request, but is at least 20 ms. During the
initialization phase after Power ON or a re-initialization operation due to a change in a CB
parameter setting, requests may not be processed at all, in which case the ensuing delay could be
as much as 40 s.
