Entering Machine Data; General Information About Machine Data - Siemens SIMATIC S5 Manual

Input
Block no.:
You select the data block number under which the generated data is to be stored. The DB
number can be a value between O and 255.
Description of the function keys
<Fl >: The destination device is the IP247 module. You branch immediately to the next dis-
play, either to the first machine data or the first machining program display.
The destination device is the programmer. You branch immediately to the next display,
either to the first machine data or the first machining program display.
The destination device is the data drive entered in the configuration display. You
branch immediately to the next display, either to the first machine data or the first ma-
chining program display.
With the help key you can select the text "machine data" or "machining program" in the
"data block" input field.
If you press the EXIT key, you return to the basic menu (function selection).

Entering Machine Data

General Information about Machine Data

5.6.1,1
Before traversing movements can be executed, each axis requires the technical data of the drive.
This information is known as machine data (=> Section 2.5 "Machine Data and their Structure").
When you input the machine data, the module checks that the data is consistent. If you make an
error, an error message is output and the program branches to the display in which the incorrect
value might be located. After correcting the value, you can once again transfer the data record to
the module.
The data block numbers of the machine data for the three axes can be identical.
When you delete and re-enter a machine data record, the reference point need not necessarily
be lost; this depends on the machine data in the new data record which have changed com-
pared with the old record (=> Section 4,3.21 "Machine Data Processing"). Zero offsets and tool
length offsets are, however, reset each time new machine data are input to the module.
The individual machine data are only explained briefly here. For more detailed information about
machine data, refer to Section 2.5 "Machine Data and their Structure".
