Parameter Assignment (General) - Siemens SINUMERIK 840D Function Manual

①
The operator selects, for example, the "Continuous traversing" machine function on the machine control panel for a
machine axis.
The input signals of the MCP are transferred cyclically from the basic PLC program in the data blocks of the MCP input
interface.
②
The PLC user program reads the input signals of the MCP. The input signals can be linked with any other signals in
accordance with the current machine or machining situation. Finally, the PLC user program writes the corresponding
request signals to the NC in the respective axis-specific NC/PLC interface.
The basic PLC program transfers the request signals in the internal input interface to the NC.
③
After activation of the requested function, the NC writes the feedback in the internal output interface to the PLC. The
basic PLC program cyclically transfers the output signals in the respective axis-specific NC/PLC interface
Further information
Detailed information on the configuration and integration of machine control panels in the PLC
user program can be found in the Function Manual PLC.

Feedrate behavior
In JOG mode, it is possible to traverse an axis/spindle manually also at a revolutional feedrate
(as for G95) specific to the current speed of the master spindle.
The setting is made via the setting data:
