13.13.28 Fc 26: Hpu_Mcp Transmission Of Ht8 Signals To Interface - Siemens SINUMERIK 828D Function Manual

Description of formal parameters
The table below shows all formal parameters of the "MCP_IFT" function:
Typ
Signal Type
e
BAGNo I BYTE
ChanNo I BYTE
SpindleIFNo I BYTE
FeedHold A BOOL
SpindleHold A BOOL
Call example
CALL FC 25 (
BAGNo :=
ChanNo :=
SpindleIFNo :=
FeedHold :=
SpindleHold :=
With these parameter settings, the signals are sent to the 1st mode group, the 1st channel and all axes. In
addition, the spindle override is transferred in the 4th axis/spindle interface. The feed hold signal is passed to bit
memory 22.0 and the spindle stop signal to data block DB2, data bit 151.0.
