This keyword allows a variable of type STRU_INT (STRUCT_P) to be defined.
It is used by the interrupt handling instructions int_timer(), int_after(), int_inp().
It consists of the following information:

•BIT 0: If set to 0 there is continuous execution of the interrupt. If set to 1 you have one-shot execution •BIT 1: If set to 0 it uses STRU_INT.count as the interrupt counter. If set to 1 it uses STRU_INT.count as a flag by setting it to 1 every time an interrupt occurs. It is up to the user to reset STRU_INT.count to zero |

intTime |
REAL |
Time [sec] relative to the occurrence of the interrupt. This time should be compared with the system parameter synch_hw_time [microsec], which corresponds to the time of the last system synch. WARNING: intTime is in [sec] while synch_hw_time is in [microsec]. To calculate at what time distance the interrupt occurred from the last system synch use the formula: delta_sec = intTime - (synch_hw_time * 1e-6). This formula should be used within the rule called by the interrupt, in which case it will always be: 0 < delta_sec < si |

maskPhoto |
I32 |
Mask of the axes whose photos are wanted on the occurrence of the interrupt |
Read/write |
nrule |
I32 |
Number of rules to be activated (it must be contained in the $ rule_time file and/or in the $ rule_inp file) |
Read/write |
pos[1-32] |
REAL |
Photographed position of axes (enabled by maskPhoto) on interrupt |
