3.5 Control Signals for PIO Operation
The contents of the signals for the input and output ports vary depending on the setting of the
operation mode.
Set the position data from a teaching tool such as the RC PC software.
The number of movement points available in the operation depends on the operation pattern
(PIO pattern) input in the initial setting.
The I/O specifications for the operation pattern are described as follows.
