Special Functions For Oem Users (Oma1 - Siemens Sinumerik 840D sl Programming Manual

4.9 Special functions for OEM users (OMA1 ... OMA5, OEMIPO1, OEMIPO2, G810 ... G829)
4.9 Special functions for OEM users (OMA1 ... OMA5, OEMIPO1,
OEMIPO2, G810 ... G829)
OEM addresses
The meaning of OEM addresses is determined by the OEM user. Their functionality is
incorporated by means of compile cycles. 5 OEM addresses are reserved (OMA1 ... OMA5).
The address identifiers are settable. OEM addresses can be programmed in any block.
Reserved G function calls
The following G function calls are reserved for OEM users:
• OEMIPO1, OEMIPO2 (from G function group 1)
• G810 ... G819 (G function group 31)
• G820 ... G829 (G function group 32)
Their functionality is incorporated by means of compile cycles.
Functions and subroutines
OEM users can also set up predefined functions and subroutines with parameter transfer.
Note
Workpiece simulation
Up to SW 4.4, no compile cycles are supported, from SW 4.4 and higher only selected
compile cycles (CC) are supported for the workpiece simulation.
Language commands in the part program of compile cycles that are not supported (OMA1
... OMA5, OEMIPO1/2, G810 ... G829, own procedures and functions) - therefore result in an
alarm message and cancellation of the simulation without any individual handling.
Solution: Individually handle the missing CC-specific language elements in the part program
($P_SIM query).
Example:
N1 G01 X200 F500
IF (1==$P_SIM)
N5 X300 ;not active for CC simulation
ELSE
N5 X300 OMA1=10
ENDIF
