High-speed Input and Pulse Output Features
DL105 PLC User Manual, 3rd Edition
The diagram below shows HSIO functionality in Mode 30. When the lower byte of
HSIO Mode register V7633 contains a BCD “30”, the pulse output capability in the
HSIO circuit is enabled. The pulse outputs use Y0 and Y1 terminals on the output
connector. Remember that the outputs can only be DC type to operate.

IMPORTANT NOTE: In Pulse Output Mode, X0, Y0, and Y1 references are
redefined or are used differently in two ways. Physical references refer to terminal
screws, while logical references refer to I/O references in the ladder program.
Please read the items below to understand this very crucial point.
Notice the I/O point assignment and usage in the above diagram:
S
Physical input X0 is not used, so the terminal screw will not be wired.
However, the HSIO function uses logical reference X0 for “Profile
Complete” contact, which is available for ladder program use.
S
X1 and X3 can only be filtered inputs in Pulse Output Mode, and they
are available as input contacts to the ladder program.
S
X2 behaves as an external interrupt to the pulse generator for
registration profiles. In other profile modes, it can be used as a filtered
input just like X1 and X3 (registration mode configuration shown above).
S
References “Y0” and “Y1” are used in two different ways. At the output
connector, Y0 and Y1 terminals deliver the pulses to the motion system.
The ladder program uses logical references Y0 and Y1 to initiate “Start
Profile” and “Load Position Value” HSIO functions in Mode 30.
Hopefully, the above discussion will explain why some I/O reference names have
dual meanings in Pulse Output Mode. Please read the remainder of this section
with care , to avoid confusion about which actual I/O function is being discussed.
