Configuration and Programming 4-15
O:e.0 Bits 0 through 7 - Direct Outputs
These bits are used for direct user program control of the outputs. Bits
0, 1, 2, and 3 represent the four Physical Outputs of the module.
When one of these bits is set, the corresponding output circuit is ON if
that output is under user program control (refer to M0:e.0 Output
Source Select on page 4-3).
Bits 4, 5, 6, and 7 represent Soft Outputs which are not physically
connected to output circuits, they are used as system event flags.
O:e.0 Bits 8 through 15
Bits 8 through 15 are reserved and must be reset to 0.
If your user program will not be using the Direct Outputs field, you
can improve system throughput by setting the Scanned Output Words
to 0.
