Description of formal parameters
The table below shows all formal parameters of the "MCP_IFM2" function:
Signal Type Type
BAGNo I BYTE
ChanNo I BYTE
SpindleIFNo I BYTE
FeedHold A BOOL
SpindleHold A BOOL
SpindleDir A BOOL
Call example
CALL FC 24 (
BAGNo :=
ChanNo :=
SpindleIFNo :=
FeedHold :=
SpindleHold :=
SpindleDir:=
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. The spindle direction feedback signal
supplied via parameter "SpindleDir" can be used as a direction input for an additional FC 18 call.

(B#16#1F)
//Slim machine control panel M variants
//signals to interface
B#16#1, //Mode group no. 1
B#16#1, //Channel no. 1
B#16#4, //Spindle interface number = 4
m22.0, //Feed stop signal modal

m22.1); //Spindle direction return
Remark
No. of mode group to which the mode signals
are transferred.
BAGNo >= b#16#10 means access to the
second machine control panel.
Channel no. for the channel signals
Number of the axis interface declared as a
spindle
Feed stop from MCP, modal
Spindle stop from MCP, modal
Direction of spindle rotation
0: corresponds to + (left)
1: corresponds to - (right)
