If the same information is sent more than once, the data record needs to be changed via
the toggle byte.
7.4.1. No action
When using the “N” (NOP) instruction, no action is carried out. The response is another
NOP instruction.
Inquiry from the master:
0xYY 0x4E (“N“) 0x00, 0x00 0x00, 0x00, 0x00, 0x00
1 byte 1 byte 2 bytes 4 bytes
Response of the SideStep:
0xYY 0x4E (“N“) 0x00, 0x00 0x00, 0x00, 0x00, 0x00
1 byte 1 byte 2 bytes 4 bytes
7.4.2. Change parameters
The “S“ (SET) instruction enables the change of a parameter in the SideStep via the
Profibus. As a response, the SideStep returns the SET instruction with the changed
parameter value. If the value is higher than the valid range, an external diagnostic error
with code 0x21 is generated; if below, the error generated has code 0x20.
Where the parameter does not exist, the diagnostic error triggered has code 0x22, and the
value returned is 0.
In case of a parameter change, the new value of the parameter is returned to the master
together with a SET instruction.
Where the parameter does not exist, the value returned is 0.

Response of the SideStep:
0xYY 0x53 (“S“) ID Value of the parameter
1 byte 1 byte 2 bytes 4 bytes
The individual parameters of the GEMÜ SideStep are on page 19.
Ex: The Mode parameter needs to be changed to Manual.
0xYY 0x53 (“S“) ID Value of the parameter
Mode Manual
0xYY 0x53 0x64 0x00, 0x00, 0x00, 0x02
7.4.3. Request parameters
The “G“ (GET) instruction is used to request from the SideStep the value of a parameter
via the Profibus. The SideStep responds with a GET instruction containing the parameter
value.
Where the parameter does not exist, an external diagnostic error with code 0x22 is
triggered.
Inquiry from the master:
0xYY 0x47 (“G“) ID2 0x00 0x00 0x00 0x00
1 byte 1 byte 2 bytes 4 bytes
Response of the SideStep:
0xYY 0x47 (“G“) ID Value of the parameter
1 byte 1 byte 2 bytes 4 bytes
When the parameter value in the GEMÜ SideStep changes, it is
immediately sent to the Profibus master. There is no need to
continuously request the parameter.

7.4.4. Read error list
The error list is requested using the “E“ (Error List) instruction.
Inquiry from the master:
0xYY 0x45 (“E“) Serial num-
ber of error
in the list
0x00, 0x00, 0x00, 0x00
1 byte 1 byte 2 bytes 4 bytes
The first error is requested with 0x00 0x00
Response of the SideStep:
0xYY 0x45 (“E“) Serial num-
ber of error
in the list
Error information
1 byte 1 byte 2 bytes 4 bytes
Attention:
•When a new error occurs, the serial numbering of the listed errors changes.
Error 0 then becomes Error 1, Error 1 becomes Error 2, etc.
•Once the error list is full, the oldest error in the list is deleted.
•If no entry on the required number is found in the error list, an external
diagnostic error with code 0x34 is triggered. In this case the response value
is 0xFF 0xFF 0xFF 0xFF
•With number 0 the current error can be monitored
•If there is no error in the error list, error 0x00 0x00 0x00 0x00 is displayed
