7.6.1. 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

7.6.2. 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.

Inquiry from the master:

0xYY 0x53 (“S“) ID Value of the parameter

1 byte 1 byte 2 bytes 4 bytes

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
