Motion Event Instructions

The minimum width of a cam element corresponds to the width of a time slot, or
1/16 the coarse update period.
I/O Subsystem
You can specify the Output parameter of an MAOC instruction as either a
memory tag or an Output Module’s data tag. A pointer to the tag is passed into the
MAOC instruction. Also passed into the MAOC instruction is an internal
parameter of type IO_MAP. If the Output parameter references controller
memory, the IO_MAP parameter is NULL. If the Output parameter references an
output module, the IO_MAP parameter points to the map structure for the
module. The MAOC instruction can then determine if the Output parameter is
associated with a scheduled output module by checking the module type stored in
the driver table.
Output Data Structure
Field Size Description
Value 4 bytes Data values for un-scheduled output bits.

Mask 4 bytes Selects which output bits are to be scheduled.
Only the first eight bits (0 to 7) or 16 bits (0 to 15) can be
scheduled.
0 = Not scheduled
1 = Scheduled
ScheduleTimestamp 8 bytes 1756-OB16IEFS and 1732E-OB8M8SR only.
