8.1.3 Setting Request / Select Telegram
Via the select telegram, the data are sent to the frequency inverter.
Positioning request PLC

frequency inverter:
Byte 0 1 2 3 4 5 6 7 8 9
…
n
Header NoB SYS DS P.-No. data
7 6 5…0 LSB MSB uint/int data
R/W 0 0 nn nn nn nnnn LSB MSB
long data
LSB MSB
string data
first
character
last
character
Header: Bit 7 R/W
1 = Setting request
NoB: Byte number Number of relevant bytes
([Byte 2] … [Byte 5] + Number of data bytes)
SYS: Addresses frequency inverters which are connected to a TCP/IP module via CAN System
Bus.
SYS = 0 for direct addressing of frequency inverter in Ethernet connection
DS: Data set number of parameter (0,1 …, 4, 5, 6 … 9)
P. No.: Parameter number (0 … 1599)
data: parameter value to be written, byte number depending on data type

Header: Bit 7 R/W 1 = Setting response
Bit 6 E 0 = no error

NoB = 6)
NoB: Byte number Number of relevant bytes
([Byte 2] … [Byte 5] + number of data bytes)
SYS: returns value SYS from the request frame
DS: returns dataset number from the request frame
P. No.: returns parameter number from the request frame
data: returns written parameter value, byte number depending on data type
