Appendix 1: Monitoring Input/Output Signals
IO: Input/Output Monitor (B3 and 23 type Driver Units)
[Example 1] Check if the start command RUN for positioning with Programmable Indexer
is inputted.
(1) Confirm that the colon (:) is on the display of the Hndy Terminal.
(If the colon (:) is not on the display, press the ENT key once.)

Explanation
l
The checking procedures described above confirm that the RUN input, start command for
positioning with Programmable Indexer, is ON as the readout of the signal is 1.
à
In case of above [Example 1], the readout of Input/Output signals will be observed and
displayed on the screen until the BS key is pressed.
à
If the signal changes ON and OFF (ON
⇔
OFF) while monitoring the state of
Input/Output signals, the readout will follow the changes with 1 and 0 (1
⇔
0) as well.
à
However, if the step (3) of the procedure of [Example 1] is omitted, the readout will be
one-shot right after the ENT key is pressed.
