Appendix E: High-speed Input and Pulse Output Features
Dedicated High- Speed I/O Circuit
The internal CPU’s main task is to execute the ladder program and read/write all I/O points
during each scan. In order to service high-speed I/O events, the DL06 includes a special
circuit which is dedicated to a portion of the I/O points. Refer to the DL06 block diagram in
the figure below.

The high-speed I/O circuit (HSIO) is dedicated to the first four inputs (X0 – X3) and the
first two outputs (Y0 – Y1). We might think of this as a CPU helper. In the default operation
(called “Mode 60”) the HSIO circuit just passes through the I/O signals to or from the CPU,
so that all twenty inputs behave equally and all sixteen outputs behave equally. When the
CPU is configured in any other HSIO Mode, the HSIO circuit imposes a specialized
function on the portion of inputs and outputs shown. The HSIO circuit operates
independently of the CPU program scan. This provides accurate measurement and capturing of
high-speed I/O activity while the CPU is busy with ladder program execution.

After choosing the appropriate HSIO mode for your application, you’ll need to refer to the
section in this appendix for that specific mode. Each section includes wiring diagrams to help
you connect the High-Speed I/O points correctly to field devices. An example of a High
06 diagram is shown below.
