High Speed I/O Wiring Methods

A a
DL05 versions with DC type input or output points contain a dedicated High-Speed I/O
circuit (HSIO). The circuit configuration is programmable, and it processes select I/O points

independently from the CPU scan. Chapter 3 discusses the programming options for HSIO.
While the HSIO circuit has six modes, we show wiring diagrams for two of the most popular
modes in this chapter. The high-speed input interfaces to points X0 – X2. Properly configured,

the DL05 can count quadrature pulses at up to 5 kHz.

It can generate high-speed pulses up to 7 KHz for specialized control such as stepper motor /
intelligent drive systems. Output Y0 and Y1 can generate pulse and direction signals, or it can

generate CCW and CW pulse signals respectively. See Appendix E on high-speed input and
pulse output options.
