Operation Theorem • 59
4.17 Interrupt Control
The PCI-8136M can generate INT signal to host PC according to 8 types of
interrupt factors, refer to _8136_S_Set_Int_factor() function for more details.
The following table represents the interrupt setting for all factors.
_8136_S_Set_Int_factor( Cardno, AxisNo, Int_Factor)
AxisNo
Int. Factor
bit (type)
0 1 2 3 4 5
0 EL1 EL2 EL3 EL4 EL5 EL6
1 ALM
2 ORG1 ORG2 ORG3 ORG4 ORG5 ORG6
3 EZ1 EZ2 EZ3 EZ4 EZ5 EZ6
4 CMP1 CMP2 CMP3 CMP4 CMP5 CMP6
5 Timer - - - - -
6 ADC1 ADC2 ADC3 ADC4 ADC5 ADC6
7 INP1 INP2 INP3 - - -
Note: EL is both PEL and MEL, EZ is index signal , CMP is position
compare true, Timer is card’s internal timer, ADC is analog compare
true. INP is motion command finished.
For each axis number, the interrupt can be set according to this table.
Because users can’t deal with interrupt under Windows System. PCI-8136M
has another way for user to receive interrupts. That is Windows message
system. This card uses events to notice user’s program if interrupt is coming.
Users can create a thread to get the interrupt events and then use
_8136_S_Get_Int_Status() to get the interrupt status. The status bits for
each axis is in the following table:
_8136_S_Get_Int_Status(Cardno, AxisNo, Status )
Bits Description
0 Positive limit switch interrupt
1 Negative limit switch interrupt
2 Alarm pin interrupt
3 ORG pins interrupt
4 Index signal interrupt
5 Position counter compare interrupt
6 Internal timer interrupt
7 Analog compared interrupt
8 Motion command finished
